Successfully complete single player mode on any difficulty setting to unlock the Foundation multi-player map. Note: There is a glitch that prevents some people from unlocking the map as it was originally intended. The way it has been done successfully is as follows: Successfully complete single player mode on any difficulty setting. Create a new profile. Begin a co-op game on the last level with the newly-created profile with the second player. When you reach a section where you fly a Banshee, the new profile must perform a barrel roll and a loop-the-loop. Finish the campaign and the new profile can access the Foundation map when hosting split-screen, System Link, or Xbox Live games. Alternately, if you have Xbox Live, go to the Microsoft Content download menu. Then, download all recently updated content. Go to a game menu. Go to change the options, then change the map. It should be at the very bottom.
This trick requires levels that have either Covenant or Marines following you. If you have a powerful weapon that has very limited power (for example, the energy sword, or Covenant sniper), or weapons that are very powerful (for example, Human sniper or rocket launcher) give them to the A.I. following you. As they use them, the weapons will never run out of power or ammunition. Also, they can use them very well.
To do this trick, your weapon must be reloadable and have at least one clip in it. When your weapon has no shots remaining, before you reload, switch to your other weapon. Find an ally that you can switch weapons with, then quickly switch to the weapon that needs to reload and swap with the ally. If done correctly, you will see your ally reload the weapon. Swap your weapon back to see that your clip is now full, and it did not take away any ammunition.
This trick can only be applied to weapons that can be dual wielded. For this trick to work, you need four dual wielding weapons in one place. Two or three weapons of the total four weapons must be the same, but remember a minimum of two of same weapon is necessary in order to have same weapon for both primary and secondary slot. For example, have two needlers, an SMG and a plasma rifle. To get two needlers, carry one needler as your primary weapon then select anything else but the needler (such as the SMG gun) as your secondary weapon. Note: You cannot select the same weapon as your secondary any way. Dual wield plasma rifle with the SMG then go to the needler that is on the ground, hold X, and substitute the second needler with the SMG gun. Then, throw the plasma rifle away by pressing B. You are left with the Needler as both your primary and secondary weapon.
You can use a destroyed machine gun; for example, in Zanzibar after you fire a rocket to one of the turrets on the left and right on the main base. Just go back to them and the screen will prompt you to hold X to operate. This can be useful during heated sessions.
Wait until a Banshee drops quite low (but you still cannot reach it). Jump before doing it. If it does not say "Hold X to board enemy Banshee", press X regardless. You might not see Master Chief leap up and hit the Elite (or other alien) out of the Banshee. Do not go too low, and drive slowly because the Elite might kick Master Chief out.
Go near a Wraith and press X. Then, press B a few times. Instead of throwing a grenade, just hop in. If this does not work, throw a grenade in the Wraith.
When in a Banshee, press A and a direction on the Left Analog-stick. When in a Banshee, hold A and press Left Analog-stick Down. The Banshee will do a backflip. Additionally, to do tricks in a Banshee, press Left or Right on the Left Analog-stick and hold A to do a barrel roll, or hold Down + A to do a loop.
In multi-player-mode, turn on all vehicles and go to a place with open space. Get in a Ghost and find a tank. Go towards it as fast as you can. You will flip and do different things, depending on where you hit the tank.
Go to any level (Metropolis recommended, when you have to get on the Scarab). Back the Ghost up to the side of the bridge. It will start hopping up and down.
Chose a level with the yellowish glowing boxes that blow up (Headlong or Waterworks recommended). Get in a ghost and boost into one of the tiny boxes and you will be sent flying. You can repeat this as many times as desired, or you can pile the boxes and be blown sky high.
When using a Spectre, go at top speed and hold A. You will do a wheelie for about three to four seconds. This is useful when climbing up walls or going over short walls.
When playing a multi-player map with vehicles, you can steal vehicles such as the Wraith from your opponent. Approach the vehicle while holding X. Note: This removes your opponent from the vehicle only; you must press X a second time to board the vehicle.
To hijack a Wraith, you must get up close to it by first destroying the side guns. You will get a message to press X. Do so, and you will be hanging on the side of it. Then, tap B to punch the door in. Next, press L and throw a grenade in. Jump off and go back in by pressing X, and you will now be driving the Wraith.
When you board a Wraith of Scorpion tank, the "B to melee" message will appear. Melee until the cover is knocked off, then continue punching. This will kill the driver without damaging the tank.
Use the following trick to knock enemies out of vehicle safely. Note: This only works with a fast moving, non-flying vehicle. First, stand by a wall or something that they can crash into. Try to get the opponent to run you over, then jump out of the way after about a second of contact. He should then crash into the wall. When he does, go directly next to it and hold X. You should now be in the vehicle.
Piggyback on a Banshee. Before one member of your team gets into the Banshee, jump on top of the Banshee's pilot cover. When you get in, you can just stand on top of it. Only make turns with the Right Analog-stick. They are slower and do not tilt the Banshee. More than one player can stay on top of the Banshee. This provides extra fun if you want to do aerial tricks with friends by jumping from Banshee to Banshee.
With almost any vehicle, you can get a piggyback if you are not skilled at driving or need a fast ride when someone on your team is already on a Ghost. This also works with the Scorpion, Banshee, and the Warthog when you have someone in the gunner seat, when you are all far enough away from the enemy.
In a multi-player level with vehicles (Ghosts recommended), stand in front of one of those barrel things that explode. Wait until someone in a Ghost sees you, throws it in turbo. and tries to run you over. At the last moment, jump out of the way. If done correctly, the vehicle will shoot past you, fly into the barrels, and explode; killing the driver instantly with a huge explosion.
While playing on a map with two Scorpion tanks available (Coagulation recommended), have a friend drive his or her tank up against a canyon wall until it flips upside-down, and your friend falls out. Drive your tank over to your friend's tank. Face the side that looks like a ramp. Line your tank up and start driving up it until one is on top of the other. While you are still in the top tank, have you friend walk over to the bottom one. The "Hold X to flip tank" message will appear. Once flipped, the bottom tank will send the top one flying high into the air (sometimes above the level), spinning at incredible speeds. After awhile, the tanks may start to catch fire and wear-down.
To destroy a Ghost in one hit (sniper rifle) or three shots (battle rifle), look on the left side of it, just under the driver's seat. You will see a gas tank of sorts. If you shoot that directly, the Ghost will explode with one hit or one burst from the battle rifle.
One of the best ways to take down a Ghost is with a sniper rifle. Wait until the Ghost is facing away from you and open fire at the pilot. If the pilot does not die, the Ghost may explode, because it is very vulnerable in the back.
Besides boarding, there is one other reliable way to take down a Wraith in single or multi-player mode. Get a Ghost and hit the booster until you are right up against the Wraith. Then, circle around to the back of it and open fire. By the time he has fully turned around to get a bead on you, he will probably be dead. If he tries to get out, you can simply pick him off as he is climbing out. Note: This may not work as well in single player mode, as the Wraith has anti-infantry plasma cannons.
This trick is reminiscent of the Warthog launch from the original Halo, but uses different methods. First, start a split screen multi-player game with just yourself on a map that has any explosive boxes (Headlong or Waterworks recommended). Then, find any of the explosive boxes and gather them in a pile near one end of the map. You can move them by pushing against them or meleeing them. However, do not melee them more than once or they will explode. After you have gathered enough, park a Warthog over them slowly and fire a rocket at one end of the Warthog. Depending on how many boxes you gathered, the Warthog should go incredibly far. Note: This takes a lot of skill and time, and should only be done if you have nothing else to do.
The following is a list of rewards you get from killing people without dying once. Note: After 25 it starts over again with "Killing Spree".
- 5: Killing Spree
- 10: Running Riot
- 15: In The Zone
- 20: Unreal
- 25: Unfreaking Believable
- 10: Running Riot
When caring an item (bomb, flag, etc.) quickly press Melee, X, Melee to perform a combo melee attack. Continue pressing Melee, X, Melee, X, etc. to make the combo continue indefinitely.
While equipped with shotgun, get in close range and press Melee, X (reload), Shoot, Melee. Note: You must press X immediately after the first melee is finished.
While holding the shoot trigger, press Melee, and immediately after the hit, press X (which instantly continues you back into shooting). Note: This can be done as long as you do not overcharge the plasma rifle.
When using an energy sword, press Melee, X, Shoot. This combination can happen very fast.
When the energy runs out, do not trade it for another weapon. When you get to the next level, try to use the sword. The ammo will be at zero but you will do full sword damage instead of melee damage and can do sword moves.
To instantly kill any enemy except Hunters and Bosses, hit them in the back with any weapon.
The plasma sword is one of the most deadly weapons in the game. However, there is a way to make it deadlier. If you are walking up to someone, you will see the aiming reticule turn red. If you press the trigger or B, you will deliver a deadly lunge that can kill almost anything in one hit. To make this even deadlier, before you reach your enemy jump and keep aiming at him. When the reticule turns red, you will still be in the air. As you are in the air, press the trigger or B and you will lunge forward in mid-air. This is more deadly because you are above himm and his head is the closest thing to you when you are in mid air.
Get two Magnums (pistols) and shoot one trigger at a time. Do not use against the Flood, as it will backfire and kill you.
To sword cancel, rapidly press B + X. This will let the sword swing wildly and is also a good way to shock opponents. To swing your sword at an enemy but not hit them (canceling your attack) press R + X. This will only work when you are locked on an enemy.
When reloading a gun, press melee immediately after the ammo is reinserted into the gun, press X. This enables you to shoot and/or zoom instantly. This works for any gun that uses ammunition.
When DWing SMGs, press one shoot trigger at a time simultaneously. This disables the reticle/aimer from going upwards. Note: This also works on other DWings.
To lock on with rockets, target a person, vehicle, etc., then hold R until it says that it is locked. The red reticle will follow the item. Release R to fire. Additionally, while using a rocket launcher, you can lock-on to the following items: turrets, vehicles, and the Phantom's plasma cannons (Covenant Dropship's turrets). To lock-on to those objects, aim your cross-hairs at the object. By doing this, your rocket launcher's cross-hairs should have four red squares on the corners. Then, hold Fire so that the rocket launcher will fully lock-on to the object. While this happens, the lock-on system of the rocket launcher should make a few repetitive beeping sounds. After the beeping sounds have ended, the cross-hairs should be completely red and ready to fire. Release Fire and your spiraling heat-seeking rocket launcher missile will go to the target.
If you have picked up a frag grenade and a plasma grenade, press Black to change from one to another.
To get some good practice in with the sword, you must have two players, both with swords. Practice hitting each other. This is useful for combat with the Royal Elites.
Have the sword when an enemy is very close. You can jump and do it, or run and jump to them, then press B. This is a one hit kill for Flood, and a two hit kill for some Covenant and the shield Flood.
Have two dual-wieldable weapons (for example, a Needler and an SMG), but do not have them out at the same time. The Needler would be the weapon that you want extra ammunition for. Have the SMG out and find another Needler to dual wield with it. Then, find yet another Needler and trade that with your SMG. You will now have three Needlers, and have three times the ammunition.
When dual wielding, it is best to think about things before you just grab a needler and a plasma pistol, and have a pistol as your third weapon. You should make it so you have a good backup weapon; when dual wielding, ammunition can go quite quickly. Have two plasma rifles (or your choice) and have something like a particle beam rifle, shotgun, Covenant carbine, or perhaps a rocket launcher so that you have something to fall back on. Some suggestions are as follows:
- Needler x2
- Plasma rifles x2
- SMG x2
- SMG and a plasma rifle
- SMG and a plasma pistol
- Plasma rifles x2
Note: Having two plasma pistols is not a good choice because you cannot hold the two triggers down, or you will power them up. You must keep pulling, making this somewhat difficult. When wielding two weapons at once, use only one at a time, and when that runs out of ammunition, use the other one while reloading. Do this to keep up a steady stream of fire.
Dual needlers is probably the most underestimated weapon pairings available in the game, and probably the most powerful as well. Needlers have an incredibly fast rate of fire, are heat seeking, do initial damage then explosive damage, and you can pick up usually 80 to 160 ammo after each bout of gun fighting (in campaign mode). The only bad thing about needlers is the fact that they ricochet off shields and some body armors (for example, Hunters and the Elite Guard). They are not recommended for fighting shield wielding enemies, Hunters, Elite Guard, or Infected Flood (as they are extremely quick and will most likely do damage to you before the needler shots explode in them). In multi-player mode with friends, there should be nothing more feared then dual needlers.
A great dual wielding combo are two plasma pistols. Early in the game, two blue ones will do. Later in the game when you begin to fight the Brutes, after they die take their red plasma pistols. The red ones are slightly more powerful and overheat a little bit faster. A red and blue plasma pistol is recommended, as they compliment each other very well. If you have fast trigger fingers, any enemy will die. Even Brutes will die within around five seconds. Be careful; watch your heat and ammo meters. The plasma pistols are very good because they are powerful, and get rid of energy shields very quickly.
Use the following trick for easy kills by dual wielding a plasma charger. Get one plasma and any other weapon of your choice (SMG, plasma rifle, needler, etc.). Next charge your plasma pistol and keep it charged. If you get a hit on your opponent, his shields will be down and you can kill him within two seconds with a normal gun.
The best dual wielding combo is the plasma rifle and the sub machine gun (SMG). The second best is dual SMGs, and the third best is a plasma pistol and pistol combo.
Dual wield a plasma rifle and a plasma pistol. While the rifle is firing you can charge up the pistol, and while the rifle is cooling down shoot the pistol charge.
Do not be afraid to retreat for a moment to let your shields recharge and reload your weapons, especially when dual wielding.
Get a Plasma Sword from a dead Covenant Elite and get close enough to the Brute for the half-circle surrounding the crosshairs to turn red before attacking. You will lunge forward and get rid of half the enemy's life. Jump into the air immediately afterwards, and do this a second time to kill him instantly. Both attacks combined cost only ten ammo points, so this process can be done ten times in succession, making it an effective way to crowd-clear Brute patrols near the end of the game. Make sure to jump in-between each strike so that the Brutes you are fighting cannot continue to ram you and drain your life. Additionally, on the last level when you are fighting the head Brute, wait for his shields to go off (when the blue gas-like thing around him shuts off). Then, shoot him in the head as many times as you can until it turns back on. Repeat this process until he is dead. Do not use an energy sword. It will not work, and he can kill you with one hit of his hammer.
When you are facing several Brutes together, such as in the Uprising level, use a weapon with good accuracy, such as the pistol. However, this may be difficult because it no longer has a scope on it. The Covenant Carbine is a good choice because it has great accuracy, a zoom, and a usable clip size. When using the carbine, aim for the skull plating they have on the top of their head. If you are a skilled shot, this should kill the Brute in about four to five shots. Have something like the energy sword as a backup in case there are too many and they charge.
Two direct head shots with a beam rifle are required if they are wearing a helmet. Pack some heavy artillery. A fuel rod cannon or rocket launcher may be cheap, but they cannot charge you if they are blown up. A few hits with the brute shot can also work; there should be plenty of ammunition for it. If all else fails and they charge, a shotgun or the blade on the brute shot can work, but it will require three shots to the face with a shotgun and three hits with the blade.
The best combination of weapons against a Brute is to use two plasma rifles. Brute plasma rifles are recommended, as they are slightly stronger and shoot faster with a slower heating process. Run up to any Brute (this actually works for all enemies except Hunters) and fire both of your plasma rifles in sequence. This means that first you fire the right (or left) gun until it is nearly overheated, then stop firing that one and begin firing your second one until it is nearly overheated. Again, start firing the other one. Keep doing this in sequence and the only thing that will stop you from shooting is running out of ammunition. A good way to do this properly is to count how long you have been shooting. Shoot with one gun at a time for about three to five seconds, then begin shooting the other one. This is very useful for big groups of opponents as you do not have to reload or wait for your weapon to cool down.
On the final level, once you reach the door that leads to the final battle, a group of Brutes will come out. Instead of fighting them, use your invisibility gear and sneak through the door without having to fight. Note: You must be fast or the door will lock.
The Brutes' weakness are their heads. That is why they usually have metal plates. Shoot them in their heads for an easy kill.
When battling with Elites, do not hit them once with your weapon. Always hit them multiple times. If you hit them once, they will have a faster time and kill you with one hit or take down your shield. Additionally, an easier way to kill Elites quickly is to double-wield the SMGs and aim for the head. Be careful, as the SMGs tend to send the reticle upward. Also, try meleeing him before using the double strategy.
You can outsmart Elites in some battles by finding cover and returning fire as usual. However, when they stop firing, relocate to other sources of cover and have a few seconds before they notice. Also throw grenades before they get all the way out, if they are appearing from a door or a ship portal.
Dual wield a plasma pistol or rifle and a Human pistol. Use a plasma pistol or rifle to knock down the shields quickly, and then shoot them in the head with the magnum.
The best way to quickly kill an Elite is to hit them multiple times with your weapon. First. hit them so they are stunned for a few seconds, then shoot them quickly. They should die easily.
Get a Plasma Sword from a dead Covenant Elite and get close enough to the Flood for the half-circle surrounding the crosshairs to turn red before attacking. You will lunge forward and kill the enemy instantly, sometimes killing two or even three if they are in close-enough proximity to the target. This attack only uses between two to five ammo points, so it can be repeated at least twenty times. Note: Do not use this trick on either the small spider-like Flood or the large bulbous Flood, as the explosion that follows will damage your shields. Additionally, to kill the Flood easily, use the sword. It cuts right through the Flood in one shot, unlike any type of plasma gun.
To make fighting Flood easier, use a shotgun and an energy sword. The Flood levels are mostly close quarters -- shoot them in the face with a shotgun. This will take down even a shielded Flood in one hit. Then, use an energy sword to vaporize the bodies so that they cannot get back up. The best part is that it will not use any energy sword power.
You can actually kill the human and elite Floods with one shot of the Covenant carbine. Aim directly at the stomach for the human-type Floods (with no long tentacles in their left arm); and aim high in the middle where the head would usually be for the Elite-type floods (with the long tentacles).
With big groups of enemies, kill off the Grunts first, as they are easier to kill and become less of an annoyance. Additionally, two slashes with the plasma swords are good against Grunts. However, hitting them with the grenade launchers three times can kill just as easily and does not use any ammunition.
Get a needler. Find a grunt and aim close to his head. Shoot him and he will jump in the air and die.
It is best to have dual Needlers and a Sentinel Beam when you are playing under the legendary difficulty setting. As soon as game play resumes after the intermission sequence, press White to turn invisible. Then, press Y to get rid of one of your guns and stick a plasma grenade to one of the guys. As soon as you do that, run to the left and behind a column. You should see a hole/hallway kind of thing. Go in there and hide a short time. You can then run out of the hole, turn invisible, and stick another grenade to one of them. If a grenade explodes and you hear a grunt or yell, you have hit the leader and not the copy. Go back and hide in the hole. This will save a checkpoint. The guy will start talking and more copies will appear. Repeat the process until he is dead. Note: Whenever you kill a copy of the Heretic Leader, it will drop several grenades, allowing you to restock.
Get a beam rifle (the Covenant sniper rifle) and fire it in the middle of their bodies where it is pink. This is more effective then pumping shell after shell into them. Because they have the new gun, getting close to them no longer works. There is another way to defeat them, but it is more costly. First, take your plasma grenades and throw about two or three of them on their pink skinny area. Then, get a shotgun (or the strongest gun you have) and pump the pink spot full of rounds until it is dead. Since they usually appear in pairs, this can waste a lot of ammunition and grenades.
You can kill Hunters without using any ammunition. If there is a Human turret nearby, use it. You will do so much damage that they will drop quickly. You can also still get close to them. Remember that you are a lot faster than they are, and pay attention to where the other Hunter is located. Sometimes you can get them to hit each other. It is also possible to melee attack them to death, but a lot of your Marine allies will probably die.
When you encounter a Hunter on any level, use your melee attack and hit them in the head. They will stand there for a moment, stunned. This is just enough time for you to get behind them and kill them. Depending on how skilled you are, it may take a few times to take them down.
When you see a Hunter, find a turret close by. Man the turret like in the Outskirts level. You must kill two Hunters to move on. There will be a turret upstairs, and when they come out, open fire on them.
When a Hunter charges, move out of his way. When he misses you, the pink spot on his back will be wide open. Use the weapon of your choice to blast him.
To kill Prophets, you must dodge there laser attacks and get up close until the message to hold X to board appears. Do so. Once onboard, tap B to attack them. Three hits should kill them. If not, repeat until it falls.
To easily defeat the prophet Regret, jump on his vehicle then hold X to board it. You can then press B to melee him to death.
To easily take down Royal Guards (red Elites with strange helms), attack them with the energy sword. Do not be afraid -- keep slashing. They will fall after about three hits. Note: If it has a energy sword, you must get the first hit or it can kill you with one shot. Do not let their armor fool you -- they are still Elites. Knock down the shields with a plasma weapon, then shoot them in the head with the pistol.
Instead of following the Marines, go staight across the bridge. You will find a sniper. Take it, then jump on the Scarab and shoot all the Elites and pilots. Additionally, if the people on the Scarab are taking down your shields, get on the gun turret. Fire at them madly. They will hide and allow time for your shields to recover. Then, jump on the Scarab and blow their head off by surprise.
When you fight the enemies on the Scarab, mostly Elites and Grunts, start running down the path. You will see rocket launcher ammunition. Collect it if you have a rocket launcher, as it will make battle easier when you enter the Scarab. Your second weapon should be a shotgun or dual plasma rifles in case you lose rocket launcher ammunition.
When playing in co-operative mode under the legendary difficulty setting, get a grenade launcher that is left over from the Brute on the bridge. When Tartarus jumps onto the spinning disks, jump onto the platform with your partner, then jump on the three disks for safety. Let your partner have a carbine rifle on the top level and have him snipe reinforcements when they arrive. Run around the middle circle, waiting for Tartarus to lose his shield from Sarge sniping him. Hit him with your grenade launcher. Hit him three times, then run away and wait. His reinforcements may appear. If they do, camouflage and run to the top level. Allow your partner to kill the Elites. Camouflage if Tartarus or Elites come to the top level. Note: Use your Brute plasmas if you run out of ammunition. There are some on the middle level, and perhaps the bottom level. Make sure your partner conserves his carbine rifle ammunition. Never fight a Brute Elite, as they will kill you in a few hits. Also, never hit Tatarus with a melee attack. Never use grenades as Tartarus will just jump. The most important thing is to not allow your partner to die. When doing this in single player mode, use the same tactics except when Elites arrive, camouflage yourself then go to top level and snipe with the carbine rifle.
When the intermission sequence ends, do not rush towards Tartarus like the others. Instead, just wait until they all jump to the other side, then jump over there. Or, you can wait for the moving platform to help you get to the other side. After you have done that, Tartarus will have a sort of "fog" around him. Get a plasma gun. Note: If you cannot find one, go to the lift, and on the top floor behind a wall there should be a box from which you can get one. Dual wield the plasmas and fire at him until the fog goes away. Then, keep shooting at him with the plasmas until he dies. Alternately, when his shield depletes, drop your gun and throw a grenade until he dies. Be careful though -- stay a good distance away to avoid being hit and killed.
When playing on the legendary difficulty setting, instead of getting out of your Banshee when entering Tartarus' base, fly it inside and up, using the boost. You will scrape the ceiling and run into the wall at the end of the tunnel, then run into the door. Get out, open the door, and take your Banshee inside the door. Kill the Covenant with it, or get out then keep flying through the doors. When you get to the intermission sequence, you will be out of your Banshee on a platform with Tartarus in front of you with some Brutes. Kill them, then turn around and go back down the hallway the intermission sequence skipped. Your Banshee will be sitting there, ready for takeoff. This makes defeating Tartarus much easier. Continually fire at him and when the sergeant takes out his shield, it will hurt him until the point that he dies. If he tries to jump on you, just boost under him. Watch out for his Brute friends that he calls -- they are very accurate with Brute shots and plasma grenades and will kill you. Also, do not fly under the platform.
Get two Brute plasma rifles and run away. When his shields are down, throw grenades then shoot him. He should die quickly.
In the last level of the campaign called The Great Journey, get to the part where you enter the control room. Instead of walking through, bust your Banshee through. When you enter the room with the Brutes, get out of your Banshee and kill them. Note: They might destroy your Banshee. Then, kill the Honor Guards. Make sure your Banshee is in the room where you fought the Brutes. Continue on foot until the intermission sequence starts. When it ends, turn around and run back. On your way through, your friends will teleport there. Keep going and get in your Banshee. Note: Do not go below the last platform levitating in the main room or the game will automatically kill you. Then, drive your Banshee to Tartarus and shoot him. Pressing B will shoot your bomb. When his shield gets down, shoot him as hard as you can.
Use the following trick in multi-player mode with someone that is trying to steal your vehicle. When you definitely know that they are trying to board your vehicle, press X to hop out as they board. This will give you about three or four seconds to blast them before they can get a bead on you. This requires some skill, but works very well. It is possible to take out a Banshee, Ghost, and Warthog with one SMG by doing this.
When someone tries to steal your vehicle (and it is not a Banshee), allow them to do so. When you hit the ground outside the vehicle, press X as fast as possible. You should steal the vehicle back from the person. Move quickly away from them or they will do the same thing to you.
When someone is hijacking your Ghost, Warthog, Specter or Banshee, wait for them to almost take it away from you (just before you lose control of it). Press X quickly to get out, then immediately after you press X, hold X. You will ditch your Ghost or other vehicle, and will not kicked off and can now hijack it back.
Your best chance of killing your opponent before he slashes you is to dual wield SMGs. When you see the enemy from a short distance, just let loose. The bullets will most likely stop the enemy from advancing and will kill him.
Play the mission on the legendary difficulty setting. Proceed until you reach the first Banshee section. Immediately fly straight down to the bottom of the level. Search the cracks where the large cylinders connect to the station to find a circle of Grunts dancing around a skull. Get the skull and the words "Grunt Birthday Party" will appear. When you get the skull, all headshots that kill the enemies will cause them to explode as if a plasma grenade were attached to them. This works well if you aim for a Grunt in the middle of a group of enemies. Also, this may only work for projectile weapons, but does work for the Covenent carbine and the Covenent sniper rifle.
On the first Arbiter mission, go to the Banshee part. Find a steeply slanted beam. Fly to it get off and go up to the top. Jump once, and once you land, jump again. Do until you die and it will look as if you are running down the beam very fast.
Complete the mission orders until someone asks you to go in the elevator. Wait until he says "Will you come in if I say please?" and walk in. When you get into the tram, face the Earth and hug the wall. Hold X for the entire ride. Eventually you will pick up a skull that says no clue to what it does (no word will appear, as with the other hidden skulls). Note: You cannot keep it as a weapon, as it is taken away after the intermission sequence. However, you can beat up the man with it.
When playing on the legendary difficulty setting, get to the part where you are in the shuttle bay where the Covenant have boarding craft attached. You can complete this level two ways. The first is to kill the Grunts with the battle rifle, then pick up a plasma pistol. Use the plasma pistol to lower the Elite's shields, then quickly take out the battle rifle and kill them before they take cover. The other method is to get a number of plasma grenades and stick them on Grunts. They will run to the Elites and kill them.
There is a great sniper location in the Ascension multi-player level. Get the sniper rifle and an SMG or a rocket launcher and grab the Banshee. Fly to the space between the two slanted forklift-type things immediately above where you would start if you were player one. Land, and get out. The Banshee will probably fall. Run up the slanted area and you can see the entire field. Because you cannot die from high places, you can drop down for a reload then fly back up.
Take the Banshee and park it on top of the tower with two beams coming out of its top. There should be a good location for your Banshee at the beginning of the two beams. On a team, have one person takes one and the other use the other beam. Remember to go to the end of them to get the best view. If you are alone, you have an advantage. If someone starts shooting at you, you can jump to the other side. You should be too far away for them to notice. If you fall off, take the rocket launcher or duel SMGs to protect yourself.
Use the Banshee and fly up to the two poles above Sniper's Roost. Make sure you have a sniper rifle.
Play the Ascension map in multi-player mode. Take a rocket launcher and before you go on the thing that shoots real high in the air, shoot downwards. You will fly up twice as high, but will be dead.
Go to the Blue base. Run to the end of the base where the ramp is located. Tilt your gun to the bottom in the "northeast" direction. You should see the "Hold X to pick up weapon" message. Hold X to pick it up. This is a hidden weapon which is useful when cornered without any ammunition.
In multi-player mode, go to the sniping location where you are able to push the rocks down in to the creek. Roll down all the rocks and look at the spots along the wall where the rocks were placed. You will find a message that reads "Why am I here" with someone's initials under it.
Play the Beaver Creek map in multi-player mode. Go up to the sniper rifle and walk across the edge so that you are behind the rocks. Turn to your right and look at the tree in front of the sniper rifle area. Jump and land directly in front on the tree. You will sometimes fall through the level and the game will say that you were killed by the guardians.
At the Red base, get a Banshee. Get on top and face toward the Blue base. Turn right and go over. Follow the wall up and close to the top. You can get out there and snipe from this location.
Use the Ghost or a miss with the energy sword to get up on the level. You can walk around the dunes, but invisible walls will stop you.
There is only one sniper spot, and one turret. If you are on a team, try to stay in the turret and on the following sniping spot. When you are alone, just take the sniper spot. To get to this sniper spot, take a Ghost and use boost to get on top of the sand hill on the side of the level, around the purple machine things.
When you get to the air lock part where the screen enters a cinematic view and the phrase "Authorized personnel only" appears at the bottom of the screen. Elites with jetpacks will come to attack you. Run past the flying Elites. Run out into space where in front of you is a pillar that slants upward. Walk all the way up to this pillar and jump on it. You should now be on the pillar's slanting portion. Walk up the pillar and you should be on top of the ship. Turn right and go straight until you pass two hallways to the right of you. You should now still be on the silver-brown part of the ship. At the very end of it you will see your path slant to the right slightly. You now can see that the only place to go is on the blue part of the ship. Jump from the silver-brown part of the ship to the blue part. Look to your right and you should see a upward path. Climb it. If desired, you can go sightseeing to your left "towards earth"; there is nothing but the cannons of the ship. Once up on the elevated part of the blue ship, you will see a gap between the blue ship and the silver-brown ship. Jump on the silver-brown part of the ship. Once on there, run towards your right. Do not go down the orange glass plated window that slants down; this will leave you at a dead end. If choose to go that route, there are pillars here that will allow you back up, like on the first step of getting up on the ship. You will come across orange windows. You will fall through some of them, but not enough to not be able to get back up (simply a few feet). You can look down into the ship from the top plated part of the glass. Jump out of these if you come across many of these non-solid pit holes. Some orange plated windows laying on the ground that have force fields. Hold Forward and jump to clear them. This can go on for a very long time.
Go to where the bomb is. Go out of the elevator and turn directly to your left and move down the hallway. Turn right and you should see no enemies, but a Marine. You will need to do this quickly. Push him up the stairs, but do not attract the guards. This will make him move. Then, push him into the ammo feeder and watch him get pushed into the wall. He will disappear. Note: If you do this, you will die and fall through the level or land on other platforms you previously visited, like the Pelican in the hangar.
In the first level, as soon as you get off the lift do not go on the train. Instead, look to your right to find a trash can. Go over to it, crouch, and look in between the can and the wall. There should be a Johnson Cigar burning away. Additionally, go to the armory. As you are coming up the stairs, you will hear the man shooting his shotgun and talking. Kill the Elites and go through the door. Jump over the turret and look to the right. Jump on the lights sticking out of the wall, then jump over the rail. Get on one of the beams and jump off it onto one of the rails. There will be a small room with no doors. Jump onto that and bash the trash can. When you look on the floor, you will see Johnson's cigar.
After things start and you are getting some weapons, go down the stairs. You will see a hat on a box of gear. Melee attack the box from under the hat, and it will float.
The best sniper spot is at the Blue base (the one with all the shadows), on the rocks above. Fly your Banshee there and land on a flat rock. You will be covered by shadows and have a view of the entire level.
Near the Blue base there is a sniping location at Mt. Erectus. You can get up there with a Banshee, Ghost or a Specter.
At the Red base, get a Banshee. Get on top and face toward the Blue base. Turn right and go over. Follow the wall up and close to the top. You can get out there and snipe from this location.
Find a Banshee and a sniper rifle. Fly to the Red base. Turn so that you looking at the Blue base, and then look to the right. You should see the boundaries. Fly over to the wall and you should see a slant. Land on the slant and you should be able to snipe from there.
Go to the Blue base and when looking towards the Red base, look to the right. You should see a shadow from a big piece of rock sticking up. This is a good sniping spot, because when you are in danger you can hide behind the piece of rock sticking up. A Banshee is needed to reach this location.
Get a Banshee and fly directly behind the Blue base. Land up there, then get left (behind) the Red base. Then, get in the peak of the rock point by the Blue base.
Take a Spectre, Ghost, or Wraith and use boost to get behind the Red base. Ramp over any ridges and rocks. Go up on different rocks and ride along the walls sideways. Additionally, on the right side of the Blue base, take a Ghost and boost at the wall. There is a location that lets you drive straight up the wall. This trick has no strategic advantage, because as soon as you hop out of the Ghost both you and the vehicle will fall down.
Get a Ghost and ride into the wall while holding A. You will begin to go straight up the wall. This only works in some places, like behind the Blue base and slightly to the left.
Play a game at Coagulation and make sure you have Ghosts. Play as the Red team and get a ghost. Get on the hill behind the Red base. Lean up against the right side of the lower rock (if you are looking at the Blue base). Turn slightly uphill until you see a vertex where the land goes upward and meets the cliff. Face it. Strafe right about five game feet, but do not move your aim. Press L and hold Forward until you reach the top. You may need to turn slightly once you Ghost moves up the wall a short distance.
Set the game so that the main weapon is the energy sword. Get a Warthog and put it at one end of the level. Have one person get in the passenger seat and look at the other player. When you lock on, hold R. Then, have the second person to go to the other side of the level. Have the other player hold X. When the player gets out, he will run in air. He will run until he gets above the other player. If you are skilled, you can get the player on the top edge of the level.
This trick requires a Wraith with overshields on. Locate the rock that sticks out. Stand up against the wall that sticks out and have someone hit you with the Wraith when they boost. If done correctly, this should shoot you extremely high in to the air. This also can work on almost every map with a wraith, but you must have oversheilds on to avoid getting killed.
Get a Warthog and face the passenger seat to a rock far away. Get a sword and get in the passenger seat. Then, have a person out of the Warthog stands by the person in the Warthog. The person in the Warthog must lock on, and when the reticule turns red, attack. It will make a sound. The person who is out of the Warthog should get to the rock and stand on it. Then, have the person in the Warthog get out. They will fly across the stadium to the person on the rock.
This trick requires a Wraith, a Scorpion tank, and oversheilds to be turned on (recommended). Have the Wraith and the tank ram each other. As they hit, have the person in the Wraith hit the turbo. This should glitch the tank and cause it to start spinning uncontrollably and bounce off of a lot of things. this glitch is alot of fun to do but it can be hard to do.
Throw a grenade on a conveyer belt. It will stick to the ground, but not move with the conveyer belt.
Play the mission on the legendary difficulty setting. Continue until reaching the area during the "push through the covenant held ruins" phase where a landing zone for the Pelican to drop weapons must be cleared. When you reach the area where Cortana says "They're pouring out of the center building", note the plasma turrets along the borders. A short distance after the turret on the left side is the outline of a sealed door in a wall. There is a rock in front of the door. Jump on the rock, then jump onto the ledge above the door. Next, jump to the ledge to the left. Then, grenade jump onto the building with the sealed door. On the roof of the building are two dancing Elites and a skull. Get the skull and the word "Envy" will be displayed. You can now use active camouflage.
In the beginning of the level when you are storming the hill, it may be tempting to pass by this part. However, stay in that area until you survive both waves of Covenant that the Phantoms drop off. A Pelican will appear afterwards and drop off a Warthog for you and your teammates.
Drive the tank around until you get to the part with all the stationary Covenant shields. Blow the shields up then quickly park the tank on several of them. Get out of the tank and then watch as the shields reform. The tank will fly, doing spins. This is even more enjoyable when you are in the tank. You will die when in the tank and it flies very far. You can also try this with other vehicles.
Get the tank and go to the area with the big castle in the middle, where you get men and ammunition. Bring the tank up to the shields (four or five), and shoot the shields with the main cannon. Go onto the shields and wait until they respawn. You will see the tank spin very fast and go very high. Note: You will die and respawn.
You will get the Marine tank after activating the bridge. You will reach a structure which the Marine will point out is the second structure. After you hear one of the Marines say "A pelican is coming in. Let's clear an LZ", you will come up on some Covenant hiding behing about six or seven lined up shields. Destroy all of them, then wait for the shields to reappear. Then, shoot them all to make them deactivate. Immediately park the tank across as many shields as you can. Get out, stand back, and the watch the tank fly.
Acquire a Scorpion tank. Then, proceed with the mission until you reach the ruins of a complex. Slaughter all the Covenant, then reach the top platform where the energy shields are located. Knock out the shields, then drive your tank on top of them. Position it correctly, and when the energy shields appear your tank should go flying through the air.
By doing this trick you will be able to drive around the mountainous rim of the entre level and to actually drive or walk under the water and all the structures. After crossing the drawbridge and taking care of a few Ghosts, continue until you reach a courtyard with a pond in the middle and a stone structure in the middle of the pond. For the next part you will need a Ghost. At the entrance, turn to your right and you will see a few trees sort of all clustered together. There is a stone wall there that you cannot jump up. However with the Ghost, you will be able to get onto the green patch and beyond. Boost if you need to and be careful going around the mountains. You can still fall to your death. If you make it all the way to the opposite end of the level, you will find yourself on a very flat piece of land.
Get the Scorpion tank and go into the temples. Go as far as the point where the Pelican drops off guns and two men, but do not wait for this too happen or it will be too late. There will be a row of mounted energy shields (the big oval shaped ones). Drive on top of three of them. Get out of the tank and shoot the three shields. Get back in quickly. The three shields will reform, and the tank will go up, with you inside. Also, if you keep trying, your tank will land in a corner and on its back. Get out and flip it on the side that is going down. This will project you onto a higher platform. Once you are on it, run to the left of it. Walk to the left and you will see a dead body with a rocket launcher and a SMG next to it. It looks like one on the men with the black helmets and suits from the beginning of the level. There will be a giant rock next to it, with a hole big enough for you to crawl in. Once you get to the other side of the rock, there will be a jagged part of the platform going outward. Next to this will be the Pelican, still suspended in air. Jump onto it (while in mid-air, press Forward to give yourself a boost). Jump once so that the Pelican will mistake you for not being on it. Once the Pelican starts to lift, stay on it until it leaves the level. You will be walking out of the game space. Note: You can climb mountains and go to the edge of the other side of the level that you were never meant to see. This may require a few attempts, but is well worth it.
There is normally a Ghost and Warthog on the lower level. To get one of them to the upper levels, drive it into one of the air units that makes you fly up. It is strong enough to bring up a Warthog or Ghost. You can now drive around the circle and run over anyone standing there.
Stand at the bottom of the stairs with the rocket launcher by room two. Aim part way up the stairs and fire the rocket launcher. The rocket will go through the walls and explode inside room two.
You can make it up to "white space" by rocket jumping up the second floor room with the slow rotating fan on the ceiling. After making it up onto the ledge below the fan, lean against one of the ledge's walls. While aiming straight down, rocket jump again to successfully make it to the top of the level. While on top you can successfully circumnavigate the entire level with the exception of the middle, which is blocked off by invisible walls. Note: This can only be done with a full overshield. Also while in this level on the bottom floor, a monkey riding a missile and a torn poster of an unknown figure can be found on some of the doors near the air-elevator.
Play until you reach the part where the Scarab is going to blow open the door. Then, fly your Banshee down to the water and get out. Walk into the water and you will be invisible to your opponents. However, you will be able to see them, making this the perfect place to go under the legendary difficulty setting to kill your enemies without them seeing you. You may also take a Ghost or a Spectre down here. If you are skilled enough, you can even take them up very close to the top of the structure.
When the Scarab blasts the door open, take your Banshee and fly to the right of the tower. When you reach a slanted part of the wall, fly as high as you can (hugging the wall), and turn your Banshee sideways. Get out. Climb up the slant and you can skip the part when you face the Brutes and land in the Boss room. This is very helpful if playing on the heroic or legendary difficulty setting. Note: Do the same on the left side on the legendary difficulty setting to find a skull.
Wait until Sergeant Johnson blasts open the door to the control room, and destroy all the enemies. A Phantom dropship will appear. Get in a Banshee and fly close above the dropship when it stops. Get out of the Banshee, and stand on top, preferably close to one of its wings so that you will not fly off when it starts to move. Keep standing on it while it starts to fly away. If done correctly, you will fly past the level's boundaries. You will be able to see the peninsula with the control building in the distance. Eventually, the Phantom will disappear and you will fall deep into the water.
At the "Protect the Scarab" part, go through without killing anything. When you are at the beach, hijack all Banshees (also may work for turrets and Spectres), and all the Brutes will appear as "zombies". The worst they can do to you is walk into you. Occasionally, an Elite will appear with a Banshee for you. Push him in the water and he will be a half zombie (will duck sometimes). He should not harm the brutes, but if he does, kill him.
At the beginning of the level on co-operative mode, make sure you leave at least one Ghost unharmed. To do this, shoot the Brute out, leaving the Ghost "rideable". Continue the level until you need to protect the Scarab. Fly to your Ghost, then drive it off the edge and onto the beach. You will die. Get a ride on your partner's Banshee to your Ghost. You now can drive it underwater until you reach the second barrier (past the first barrier, at the part where the graphics go away). You can also climb up the tower with the Ghost.
This location requires a Banshee to reach, but you will be next to untouchable once you are there. After getting a Banshee go to the right. Just after you have passed the cranes, carefully land your Banshee on or near the walkway that has the Human sniper rifle on it. From there, get back in your Banshee and go straight up to maximum altitude. If done correctly, you should be just above the top of a building that is slightly smaller than the two other buildings adjacent to it. Land your Banshee on it, but do not destroy it. Take out your sniper rifle and start shooting. From here, the only reliable way someone can kill you is with another sniper rifle, and they cannot physically reach you because you have the Banshee.
In multi-player mode, go to the Headlong map and make sure there is a Banshee. Get in the Banshee and fly over towards the opposite base. Between the Warthogs and the water, you will see a building with a ramp leading up to a flat surface. Fly the Banshee at a high level towards where the ramp meets the wall either on the left or right side. Then while not in turbo, gently glide towards it so that the wing will just barely scrape the wall. You will slide up to this flat surface and be able to walk around, although your Banshee flying is limited. You can walk behind the buildings and be able to see through walls. On the surface to the left, you can jump up to the next platform by using the Banshee as a boost. Put it against the wall and jump up off it. This allows you to get a good sniper location. This can also be used in System Link or Xbox Live.
Select multi-player mode and choose the Headlong level. Go to the Red base. On some of the yellow walls, there is graffiti. Some it includes is a hippo head. This is a reference to former Bungie member Alex Seropian's new game company's (Wideload Games) logo.
Play the mission on the legendary difficulty setting. After you cross the light bridges and fight through to the end of the level, you reach a room where Cortana says "Brood and Elite ships are engaging all around. The next lift will take you up to the conduit. Hurry". Go to the room, enter the lift, and look up while going up. Hold X so that you can grab the skull on the way up. The word "Iron" will appear when you get it.
When playing Oddball or Team Oddball, the ball is always in the middle of the field. You may get stuck under the ball when everyone on the other team is on the platform with the ball. This can change -- if you are under the ball when it is in its spawn location, jump up and hold X. You will grab it through solid ground.
Go to sniper rifle hill (where the sniper spawns). Turn around and start to go down the walkway. Look to your right and you will see a ledge. Get on the ledge and follow it around until you reach a corner. Start jumping and have your partner sword cancel at you. You will shoot up to the roof. Then, use the rocket launcher lunge trick to go up there with them.
Play the level on the legendary difficulty setting. Immediately after you exit from the underground highway, you will reach a large open-air circular room with a handful of Jackal snipers and some Elites. The quickest way to get safely to the skull is to get the next checkpoint by jumping into the Warthog and letting the Marine drive you to the next area. Jump out of it, backtrack to the large room, and clear the area. You will see a large semi-circular beam going from one of the main platforms that goes from the ground up to the top of the two towers. Do a grenade jump at the bottom of this beam and walk all the way to the top. Jump over to the ledge of the left tower. Walk to the end of the ledge and you will find the Catch skull. This skull allows enemies to drop two plasma grenades, and all enemies will toss more grenades in general.
In the Metropolis level, there is a giant soccer ball. In order to get it, first get the Sputnik mode skull. Then, get to the part where you have to help the Marines trapped in the building. Immediately after you drive out of the square room with the waterfalls, look straight out and up. There is a building with a big glass wall that is broken at the top. Grenade jump into the building then jump on busted beams. Get on top of the building. From there, go to the right and there should be another busted-up building with a giant soccer ball for your enjoyment.
Use the following trick to get a Scarab gun on Metropolis. When you start the mission, kill the two starting Marines that you have, because they will eventually destroy the Banshees required later. Then, get in the Warthog and do not bother killing anything -- just drive straight past the Ghosts and Wraith tanks. When you get to the part where the Banshes fly overhead, kill everything there, including the Marines. Note: Kill everything except Banshees and one Ghost. Then, hijack the Ghost. Go into the tunnel and get a Banshee to follow you. Do not destroy it. Also, do not try to board it, because it will either throw you back out of the tunnel or will explode. Have it follow you to the part where you need to go through a tube. Once at the beginning of the tube, make sure you have the "Hold X to jack Banshee" icon on your screen. Melee the Banshee so that it will come towards you slight. Then, just as it reads "Loading...", hold X to hijack the Banshee. You have about two seconds before the Banshee disappears. Once you have hijacked the Banshee, fly it through the tube. This will take some effort, but can be done. Once you fly it through, fly up and northwest of your position. You will see a giant bridge-like structure very far away from your position. Once you have flown up to the top of it, there should be a small orange triangle with an exclamation mark on it, with white slashes around its border. There is also a plasma rifle floating above it. Although marked as a plasma rifle, it is really a Scarab rifle. It will produce shots like the Scarabs do, and will not run out of ammo or overheat. It is extremely powerful and takes pretty much anything out in one hit. Note: Do not shoot to close to yourself, otherwise you will blow yourself up.
First, follow the Marines out to the bridge (or walkway). Next, switch your battle rifle with the rocket launcher. It should be a few steps north of the sniper. Then, go next to the second rocket launcher. It will be a few steps ahead. You should see ammunition next to it. Instead of following the Marines, make a turn into the walkway in which there is only one way in and out. The Scarab should shortly arrive, but it will not see you. They will probably fire at the Marines. When they get far enough, there will be a huge entrance to fire a rocket at. If you followed the Marines, it will be harder to shoot the aliens on deck. Rapidly shoot rockets at the side entrance of the Scarab. When all forces on deck are defeated, join up with the Marines and jump onto the Scarab. No one will attack you if you try to hide on deck from the Elites.
Go to Metropolis level (easier in co-op mode). Go in the middle of the bridge where the Banshees come from. From there, the Banshees should attack you. When this happens get in it (knock them out). Fly the Banshee down to where the Covenant ship is located. Have the other player take out the guns on it. Once the guns are destroyed, jump off the Banshee above the Covenant ship. Stay on it. It should take you to a flat surface that in the distance where there are buildings. You can walk through them.
Near the end where you reach the Marine HQ and the Scarab almost crushes you, you will board the Pelican Dropship. After destroying all Covenant forces in the area two Pelican dropships will approach. One is carrying a Scorpion tank, and the other is carrying a squad of Marines. The dropship carrying the Marines will not touch down, but will hover about twenty feet from the top of the second ramp. Before the ship arrives, drive a Warthog up to the area where the Marines fall out. As the Marines jump, stand on the Warthog and look up to the end of the ramp of the Pelican. As you are suspended, press X repeatedly or hold that button. You will sit in a Pelican seat, and the marines will jump back in with you. The Pelican will lift off and fly through the city and out towards the harbor. It will then fly in awkward patterns and start crashing into things, shaking the camera violently. You and the Marines fall out and onto somewhere on the edge of the map. You land somewhere different every time. Most often, you will land on top of a ledge or in midair above the water. The pelican Will be located a few yards from you, spinning and twirling in the air. Approach the Pelican and the message "Press X to flip Banshee" will appear.
Proceed through the level as usual. When you reach the part where you enter the building with the trapped soldiers, get a Ghost and go into the room with the soldiers. Try stealing one before they all blow up. Note that one of the soldiers will say "Nice ride, Chief". Keep going up the stairs until you get outside. Go to the end of that area where you get on the Scarab. Blow the machine gun off and push the boxes off the side. Wait for the Scarab (unless it is already there), then jump onto it. Note: Do not get on it anywhere else or the Ghost will explode under the other bridges. When you are on the Scarab, you can go on top and the Ghost will freeze. When you get off it, it will still be hovering. Before you get on, make sure to kill all the enemies on the surface of the Scarab or they will keep stealing it or just drive off the ledge. Note: This does not give you any advantage.
When fighting the Scarab, the giant supertank, after it destroys the Scorpion it will start moving towards you. Look to your right. There should be a thin ramp-like spot. Run up this area before the Scarab reaches you and stand in the big flat area, watching it get closer. When it reaches you and starts going over another wall, jump and you will follow it. Normally the wall is too high, but when under the Scarab you can jump about twice as high.
After you go down the swirling elevator and enter the room with the big glass windows, destroy all the enemies. Then, grenade jump to the opposite side of the second floor. There will be four Flood soldiers shaking on the ground with a skull between them. Get the skull and the word "Famine" will appear.
When you begin the mission, your vision will get blurry. When it returns to normal, you will see a blinking door. Enter it, then stop. Look up to see a fluorescent light over the door you just used, and another one on the opposite wall. Jump and duck at the same time to get on one of thos lights. Do the same thing again to get onto the ledge next to the lights. Look to the left on the ledge and you should find a dark passage. Follow it to find some grenades, a skull, and a camera at the end. Take the skull and your HUD will disappear and the word "Blind" will be displayed. You will not be able to see your weapon, body, shields, ammo, or HUD. You can use the skull as a melee weapon, which does good damage to opponents. However, using a grenade, firing a weapon, trying to drive, or using a turret will drop the skull. Additionally, you can be a passenger in a Warthog and still keep it. To return to normal vision, save and quit the game, select the Cairo Station mission in campaign mode, save and quit the game, then return to the Outskirts level.
The level just has the Master Chief awakening and is stopped with the haziness. Walk forward as if you are going to proceed through the level as usual In the first hall, there will be a grunt. Kill the grunt but do not go outside. Stay in that hallway. Look up in that hallway to see light type panels. If timed correctly, you can jump up onto the panel. Beside you will be a wall that you cannot jump to. Look back and face the original wall you were looking at when you jumped up. Throw a grenade against the wall, looking down slightly so it will stop bouncing at your feet. When you count to about three, jump in the air and begin to go to the wall with the slanted top. The grenade will explode and boost you up further, putting you on top of the wall. You can then do two things. You can look across and continue with the level or you can look the other way to find a skinny passageway with the Blind mode skull , grenade, and camera type thing. If you continue to use grenade jumping, you can skip major parts of the level.
Once you can move, go into the door in front and look up. You will see a light sticking out of the wall. Crouch jump to get on top of it. Next, jump on the roof to your left. Once on top, take another left down the narrow hallway. Look on the ground at the end of the hallway. You will see a skull, a camera, and five grenades stacked in a pyramid shape. Hold X to pick up the skull. The word "Blind" will appear, and your HUD, arms, and gun will disappear. However, you can still use them. If desired, you can go around and hit people with the skull.
Note: This may require several attempts. Play the level on the legendary difficulty setting. The main thing appears to be getting the checkpoint just past the Pelican that picks up Johnson. This checkpoint spawns the sniper Jackals in "sniper alley". The skull itself is in a room on a balcony. The room contains a sniper rifle and sniper ammo; it will also contain the skull. Picking up the skull teleports you to the ground level and gives you just a Plasma Pistol. You will quickly be assaulted by Elites. Killing the last Elite will have the text for the skull flash. You have to kill all of the Elites to actually finish getting the skull. If you die to the Elites, and your checkpoint no longer spawns the skull, kill yourself four or five times to get pushed back one extra checkpoint. The skull should spawn for you again, and you can try the fight again. When you get the skull and kill all the Elites, the phrase "I Would Have Been Your Daddy" will appear.
Start the Outskirts mission on legendary difficulty setting. Play until you get to part where Sarge is airlifted out by the Pelican. Defeat all the enemies in the next area, where there is six snipers, the army of buggers, and the invisible Elites. After they are defeated, turn to face the next alleyway. There will be a couple of Jackals and two snipers down the way, and one that will not reveal himself until you fire a shot on the walkway above with the two archways. Defeat them, then jump on the awning at the beginning of the alley. Next, jump up on the beam in front of you. Walk across the beam to the rooftop across the way. If you get stuck, crouch and walk. Continue forward. There will be one more sniper to the left between the buildings to the right of the "L" shaped roof. Jump across to the roof where the hidden sniper was located (the one that was above the two archways). Make your way across to the larger rooftop. Immediately turn left towards the alley. If you walk too far across the roof, a sniper will come out. When there, look across the way. You will see some sniper ammo. Jump across to that side, and it will say "Checkpoint". There will be a room to your right. Inside is a sniper, more ammo, and a skull. Once you pick up the skull, the screen turns white and you will end up in the alley below with a plasma pistol and an elite with a sword chasing you. Note: Once you finish or die, the skull does not come back for any profile you use. After you are done, it puts you back before you picked up the skulls.
On the easy difficulty setting, go to the part where the Grunt is walking up the stairs. Look at him. Then, do a 180 degree turn. You should see two lights on the left and right. Jump on the right one. Turn where the Grunt was then look up. You will see a slanted ledge. Do a crouch-jump and go up. Then, turn around. You must jump to the next ledge and turn left. You need to use a boost to get up. Continue along the level on top of buildings. Then, look down. You will see part of a broken building. Jump down and you will see a sword sticking straight into the ground through a Marine corpse. Swap your weapon for it. It has infinite ammunition.
After you kill the Hunters and go around the corner, jump on the boxes and then the ledge. Keep going to find a dead Marine with a sniper rifle.
In campaign mode, when you get to the tunnel, get a Marine to drive your Warthog and hop out. There are a couple of Ghosts nearby. Get in one and drive off. If you look back, there will be not one, but two Warthogs, both with Marines on the gunner's seat tailing each other.
First, kill all of the Marines, even the one at the cables that you save. If you do not kill them, they will shoot down the Banshees. After you kill them, hop out of your tank, jump on its turret, and crouch. Wait for the Banshee to swoop in and shoot when it gets close to being overhead. Jump and hold X so you can board the Banshee. You may have do this multiple times until you can board it. Once in the Banshee, fly around and have fun. Do not worry about flying because there is an invisible wall above. You cannot die unless you jump out of your Banshee or go off the bridge.
At the very start of the mission, go into the hallway with the Grunt. Once you enter the hallway, look across from the door and there will be a light. Jump on the light then crouch jump (jump and hold Crouch) to the roof. Look to the left past the Blind Skull passage and you will see a ledge. Walk to the ledge, look to the left, and there should be a hole and a hallway-like ledge that you can jump to. Jump to it. Walk to the end until you hit an invisible barrier, then look to the right wall. Do a grenade jump to a rooftop beside the wall. If you cannot make it, try getting the Sputnik mode skull first. Go to the right, and you may hit an invisible barrier. However, you can jump over it. Look to the right and jump onto the rooftop. Look straight ahead, and there should be a hole and a building. Jump over or go around the hole. Hug the building, but walk along the rooftop toward the courtyard. When you get as far as you can go toward the courtyard, go to the left. Go as far as you can and get on the black ledge to the right. Go to the far end of the ledge, then look to the left and get on the rooftop. There will be another hole that you can jump over or go around. Go to the right and go to the far end and take a left. You will find a half-destroyed bridge-like building. Get on it and stop. Note: Watch out for the hole in the middle. Look to the right, and there will be two pillars holding up the bridge. Get on the closest one to you. Run across it and jump to the closest rooftop. Run to the far end of the rooftop and jump as far as you can. You may fall in an area, but can climb out on boxes. You should now be at the area where the Pelican arrives to pick up Sarge. It may not arrive, but if it does not it is not a problem. Then, continue the level as usual.
After Sarge leaves, continue ahead. Instead of fighting in this area, you can skip it. Quickly jump onto the green dumpster on the right side. Then, jump onto the roof/ledge directly in front and next to it. Walk up the roof and jump on the pipes on the adjacent wall. From there, you can jump on to the even larger roof section. After jumping on the big roof, you can skip that area. This is useful when playing on the legendary difficulty setting.
When you are playing the Outskirts level, Sarge will come along, but he is invincible. You can use him to your advantage. If you are playing under the legendary difficulty setting and your shield is down, stand behind him when he is shooting Covenant. This should give you some time to restore your shield. Also, he has infinite ammunition. If you find a very good gun but are very low on ammunition, give it to Sarge.
After going through the hotel part, defeat the aliens then go to the downed Pelican. Once facing it, look back from where you came from. Turn slightly to the left and you will see a balcony .This is where the Warthog will appear. However, for it to appear go along the regular way and kill all the aliens until you reach the tunnel entrance. Then, turn around and go back to the balcony. It should now be there. Get in and drive straight into the flower pot. You should go up it. If it gets stuck, just blow it over the fence with a grenade. The engine will catch fire, the Warthog will get damaged, but it never blow up.
When you wake up, exit that door but do not kill the Grunt. Instead hop up onto the flickering light by the elevator then look to your left. There will be a wall that you can jump up onto. Jump and crouch to get up there. You can now walk around and get on top of buildings by using grenades to boost you up.
Play Quarantine Zone on the legendary difficulty setting. At the start, turn left immediately. You should see an Elite, and just slightly to the left of him should be a cave. When you reach the exit to the cave, there should be a cliff. Follow the cliff to a wall. Along the wall should be a small walkway. Go on the walkway. At the end of the walkway should be a skull. The world "Sputnik" will appear when it is picked up. Explosion and melee forces are greater in this mode.
Play the mission on the legendary difficulty setting. Enter the structure after getting off the gondola. Jump on the large stone block to reach a ledge leading out to the Covenant turrets. Turn around and face towards the structure. Then, jump up to another level around the right side of the structure. Continue to find a skull on a ledge as you make it around. Take the skull and the word "Assassins" will be displayed. All enemies in the game are permanently cloaked.
When you can kill the Prophet of Regret, run to him. You will be able to board his floating "chair".
When you see the dead Brutes, shoot them and look at their eyes quickly; they will blink. Note: This may take a few attempts, as they will not blink all the time.
Fly up to the center machine in a Banshee. Park beside the ledge with the moving metal "shield". Go inside the room. The metal shield will block, and you have a very good view of half the level and a shield which repeatedly falls over, blocking you from enemies. If someone finds you, wait until the shield drops then run around the ledge to the other side of the level and start sniping from there.
Get a Wraith or Scorpion tank on the windmill and let it take it to the top. When it falls down, run under it. Sometimes you will break through the floor. This can be used as a trap for enemies in capture the flag.
To get the sword in the middle (if it is on) go to the Ferris wheel-type object in the middle. Line up with one of the blades. Let it push you up the circle until it is parallel with the floor. Then, run forward to the center of the circle. Jump down so that you can see through the center of the "Ferris wheel". Wait until a gap appears in the floor, then jump down and forward to the sword. Additionally, you can get the energy sword faster by shooting a rocket or grenade at the front or back of the bridge that is standing up. It will fall down and lead you directly to the sword.
Starting at the beach, run along it and then left into the opening (get a Ghost if desired). Upon arriving at the giant wheel in the center of the map, you will see the sword shimmering in the center of the structure. Toss a grenade or blast a rocket inside the little space where the sword is kept, and it should fall out and onto the ground before you. This is especially useful if you spawn at the beach, because the other team will not have a chance at getting the sword before you.
On defense, go up the slope with the needler next to it. Keep going to the right, then right, and right up the stairway until you see a rocket launcher. Get it, then go inside the spinning wheel and wait for their Ghost or Warthog.. This is a very easy way to get kills, and triple kills from the Warthogs. Be on alert for snipers. Zoom in with your rocket on the left side if you suspect one.
On offense, go up to the control tower. An easy way to find it is by the plasma gun and three plasma grenades next to it. There should be a camouflage. Grab it. Next, there will be a huge machine directly next to you. If you climb up and go in the spinning wheel you will find a hole. Go in it and wait until it spins you to the energy sword. If you get the sword first, then go for the camouflage, you will get many kills if you slip into the defensive base.
When you are on offensive, go up the stairs to your left. There should be a sniper with some grenades next to it.. This is a great way to kill people on turrets, grabbing the rocket launcher, and people trying to get the energy sword. If you take out the man with the rocket launcher, you can jump into a Ghost and be ready for some massive kills.
Put your overshield on before you start and set the level for all rockets. You can get on top of the building with the gate that you can open. There are wooden window covers. If you go up the dirt road directly next to the gate, you can crouch/jump onto those covers. It is recommended that you use the far one because they will fall down when they are shot. Get on top of one, then look down. Turn sideways, then shoot the cover. When in the air, move the Analog-stick toward the building to get on top. This is a very good sniping location.
Go to the back left of the map. You will see two awnings over two jut outs of the building. Go on the first jut out and jump on top of the second awning. After you are on the awning, throw a sticky grenade at your feet (make sure it is not on you), and jump just as it explodes. If done correctly, you will get on top of it so you can run around the top of the building.
Use a tank, push it up against the far wall by the building, and get it stuck there. Jump on it to the top then get on the roof. Another way is go up in the building and get to where the metal rain gutter panels are found (above the gate that opens). Get two people up there then get on top.
When you start the level, get inside the ring and ride it up until you reach the bridge which has not been shot down. Jump off onto the top of the bridge. Turn around and jump to the right, onto the ring. This may require a few attempts.
Use the following trick to get in the top of wheel or get anywhere desired in multi-player mode. Get into the passenger seat of the Warthog and have a sword. Then have another player get in front of the Warthog. Lock on to them, then hold R. Allow your target to walk about 80 yards. Then, have the player in the Warthog with the sword look up, release R, and press X (while still looking up). You will fly straight up. To get on the top of the wheel, just get the Warthog slightly in front of the Archer by the beach and look at the wheel, Then, get into the passenger seat of the Warthog and have a sword. Have another player go in front of the Warthog. Lock on to them, hold R, and let the other player walk straight to the building and stop. The player in the Warthog with the sword should look up, release R, and press X while still looking up. You will fly straight up and stop on the wheel. This may take some time to do and determine the correct position to place the Warthog.
