Hades Gamma Cluster hidden missions

To play the hidden mission in the Plutus system of the Hades Gamma Cluster, get 75% Renegade. To play the hidden mission in the Cacus system, get 75% Paragon.

Infinite credits

The following trick only works between the two indicated vendors. You can usually buy items back from Expat at half the price you sold them to Dr. Michel for. First, successfully complete the side quest involving Dr. Michel (from the Med Clinic) and her blackmailer. After the quest is complete, you will get a discount from all the goods she sells. Start selling her all of your expensive equipment. Then, travel to the Wards Markets, and talk to the merchant named Expat. You can buy all of your items back for cheaper than you sold them for. Return to Dr. Michel, and sell her all of your items again. Repeat this process as many times as desired.

Infinite Paragon points

Go to your Galaxy Map, and travel to the Attican Beta cluster. You will receive a message from the Alliance Command telling you about a downed recon probe that you must retrieve a data module from. From there, travel to the Hercules system, and continue to the planet Eletania. After you reach the downed probe, you will discover that a monkey-like native has made off with the data module. Get back in the Mako, and go to your map. You will see three native colonies. Go towards the one in the middle of the three. Then, go into the mining shaft, and proceed through the tunnels until you reach the end. Search the two monkeys in that part of the shaft. One of them will have the data module. Save the game immediately after getting the module. Then, reload the saved game, and continue to press A to keep searching the monkey that had the data module. Your Paragon meter over the radar should increase each time you select the monkey. At approximately 300 Paragon, you will get the “Paragon” achievement. Note: If you have already completed this assignment, this glitch cannot be done.

Infinite Paragon and Renegade points

On the Noveria planet, go to the hotel bar, and look for a Turian named Lorik Qui’in. Accept his quest to steal the data from his office. Once you get the data, the receptionist will ask you to get Qui’in to testify. Tell her you will do it, and then talk to Qui’in. Tell Qui’in that he should testify (top left option). When he refuses, select the Charm option (top left) for Paragon points or the Intimidate (bottom left) for Renegade points, and end the conversation. Talk to him again, and ask about the Matriarch. When he gets done talking about her, select the “Other questions” option (bottom right). You should now have the option to ask him to testify again (top left). He will refuse, and you will be able to use the Charm or Intimidate option again to gain another 24 Paragon or Renegade points. Repeat this process as many times as desired. You can also easily get the “Paragon” and “Renegade” achievements with the glitch.

Easy experience points

To gain extra experience from battles, make sure to get out of the Mako for the final hit. You can weaken the stronger enemies from inside the Mako and then get out to finish them off. You will only get 60% of the experience if you kill enemies with the Mako.

Easy Mako repairs

If your Mako is badly damaged and you do not want to or cannot spend Omni-gel to repair it, save your game, and reload it. Your Mako should now be totally repaired.

Weapon that does not overheat

Get a HMWA X assault rifle with Frictionless Materials, Combat Optics X, and Snowblind Rounds X as upgrades.

Saving weapon points

If you are a Soldier, level up weapons so you can use their bonuses and no further. For example, carnage is the shotgun’s bonus. By doing this, you will have extra points for a desired weapon and points to level everything else completely out. You do not need the damage and accuracy bonus from the points because when you become a Spectre the best of every weapon becomes unlocked in the Normandy or at the C-SEC requisitions office.

Lethal sniping

Equip any good sniper rifle (powerful and accurate) with High Explosive Rounds (highest level preferably). This combination will kill nearly every normal enemy it directly hits, and severely damage enemies in their proximity, if not killing them as well. For fun, if you shoot at the enemy’s feet or the ground he is standing directly on top of, he will jettison into the air. Note: High Explosive Rounds work best only with sniper rifles as they are meant to kill with one shot. If it is used with a pistol, assault rifle, or shotgun, the weapon will overheat in less than five shots (depending on the type of weapon), regardless of upgrades and decency of the gun. This will make yourself vulnerable to enemies.

Recommended weapon upgrades

The best weapon upgrades on any gun are Frictionless Materials X (28% heat damping, +7% damage), Kinetic Coil X (28% weapon stability, +7% damage), and Slegdehammer Rounds X (50% weapons force, + 60% poison damage, – 20 heat damping). Overall, the weapons stats you will end up with are 14% damage, +28 weapon stability, +50% weapon force, +60 poison, +8% heat damping. The poison damage also prevents shield regeneration. Also, any of the following combo of any grade is the best.

To build the most powerful weapons in the game, use the following. For pistols, assault rifles, and shotguns, use Frictionless Materials, Scram Rail, and Inferno Rounds. Once you can get the “X” level equipment, these will be the most powerful weapons in the game, but the combination should be used at any point you find these materials. For the sniper rifle, use two Frictionless Materials and High Explosive Rounds. The assault rifle will not overheat much at all, but for an assault rifle that does not overheat, you can use two Scram Rails and Snowblind Rounds. It is not as powerful as the first method, but is efficient.

Finding all elements

The best way to find the elements, minerals, and anomalies on planets that you can explore is to drive along the edges of the operational area (the red area). Drive the Mako in a circle around the area to where you can barely see the edge of the red line. You should find at least two elements/minerals on each planet that can be explored. There are rare things that will not show up on your map — you will also have to drive around like this to find them. There are several more items than you are required to find, but it is good to go ahead and get them if you need the experience points. Also, if you say the correct things to the Asari Consort, she will give you a trinket that will allow you to activate a Prothean Orb found on Eletania, or the “monkey” planet, in the Hercules system. It contains the memories of a Cro-Magnon that was observed by the Protheans. The Orb will show up as an anomaly on your map, in the lower left corner.

Character classes


    Adepts are biotic specialists. Starting out equipped with pistols and light armor, the true strength of the adept is through the upgradeable implants that give them their biotic powers. These powers can be used to lift or throw objects, shield the party, and disable or destroy enemies.


    Engineers are tech specialists. Using the holographic OmniTool, they can decrypt security systems, repair and/or modify technical equipment, disrupt enemy weapons or shields, and heal their party. Even though they begin the game with only pistols and the OmniTool, engineers can unlock the ability to wear light armor and reverse engineer enemy technology. They can also learn to put up protective shields and heal the party.


    Infiltrators combine combat and tech abilities, and specialize in killing or disabling enemies at long range. Infiltrators are trained to use OmniTools, but the focus is on decryption and offensive abilities rather than healing. They can train with pistols or sniper rifles, and can learn to wear medium armor.


    [lasso rel="amzn-meta-quest-3-128gb-breakthrough-mixed-reality-powerful-performance-asgards-wrath-2-bundle" id="175390"]

    Sentinels combine biotic and tech abilities. Typically they use biotic abilities and advanced healing skills to defend allies, though they can also disrupt opponents with biotic or Tech attacks. They are more efficient at tech and biotics than other classes, but at the expense of combat. Sentinels can only use light armor, and receive no advanced weapon training.


    Soldiers are combat specialists ideal for the front lines of a firefight. Soldiers begin the game trained with skills in both pistols and assault rifles, they have improved health and the ability to wear medium combat armor. As you progress through the game, you can unlock assault training, skills with shotguns and sniper rifles, become able to perform first aid on yourself and party members, and wear heavy combat armor.


    Vanguards are biotic warriors. They combine offensive biotic abilities and weapons training to quickly take down opponents, and are especially deadly at short range. They can train with pistols and shotguns, and can learn to wear medium armor.

Recommended career

Play as a War Hero Soldier first. By doing this, during your second play through you will have all of the money, weapons, and armor to use for the other careers.

Ensuring experience points and gamerpoints

After a major plot has been played, make sure to talk to your crew. This will give you experience points for clues and boost your crew’s morale. There is also a subplot for romance where you must choose who you want to have a relation with. You may lose the gamerpoints if you do not talk to the crew.

Scan the Keepers in Citadel

After you speak to Chorban in the Citadel Tower, he will request that you scan the Keepers to collect data. There are 21 Keepers total throughout the compound. You will forfeit the chance to do this sidequest if you complete Jahleed’s Fears. Here is a list of their locations:


    One is in the hanger bay through C-Sec.
    One is in the right-most room in the Presidium Wards Access corridor.
    One is in the alleyway next to the market and Choras Den.
    One is in the upper market area.
    One is in the C-Sec Requisition Office.
    One is in the Traffic Control Room in C-Sec.
    One is inside Flux, by the quasar machines in the back left.
    One is to the right of the Med Clinic entrance.
    One is at the C-Sec Academy entrance.


    Four are inside Citadel Tower.
    One is in the back room of the Emporium, left turn.
    One is on the balcony of the Embassy lounge.
    One is in the rectangular room at the right of the C-Sec HQ at the embassy.
    One is outside Citadel Tower to the left of Avina.
    One is in the Volus/Elcor office at the Embassy.
    One is opposite of Avina, halway between the Consort Chambers and the Emporium.
    One is outside the entrance of the Consort Chambers.
    One is outside the Wards Access entrance, very close to the arguing Preaching Hana and C-Sec officer.

Signal tracking in Citadel

While in the FLux, you will see a Quasar Machine that has a strange signal coming from it. It traces to the following place in order:

    Wards Access Corridor: From the Medical Clinic, go to and up the elevator that takes you toward the Presidium. Take this corridor to a little area where people are talking. Check the terminal on the wall.

    Financial District: Check Volus’ Office, behind Volus.

    Emporium: Turn right coming out of Volus’ office, and go past the Emporium Shopkeeper to a back hallway. Then, turn right again. Here you will encounter an A.I. that threatens to blow you and itself up. After the conversation, select the A.I., and input the code to override. Finish before it is done Siphoning off credits, and you will get those credits. The amount varies, but you will get more the faster you enter the override code.

ExoGeni PSI puzzle in Feros

In the ExoGeni facility, there are several claws that feed power that must be terminated to continue the mission. You will come across a control panel for the Shuttle Bay Door Controls. This panel has five switches of different pressures:

    (5 PSI Valve) (7 PSI Valve) (17 PSI Valve) (11 PSI Valve) (13 PSI Valve)

The objective is to add just enough pressure to fill the gauge between the two arrows. Too much will reset the puzzle and you will have to play with different combinations. Once a correct pressure is reached, the bar will turn yellow and text under it will read “WARNING, HIGH PRESSURE”. Enter 7, 11, and 13, then activate. This will create enough pressure to break the claw and deactivate the Geth power being flushed into ExoGeni.

Puzzle solution in Noveria

On the planet Noveria, you must solve a puzzle after you enter the Core at Mira to restore activity to the compound. The solution is as follows. There are three columns. Four discs are in the left column. You must move all four discs to column two or three for the puzzle to be completed. “1” indicates the upper most ring, “4” is the lowest, etc.

Step 1

    Move 1 to the middle.
    Move 2 to the right.
    Move 1 to the right on top of 2.
    Move 3 to the middle.

Step 2

    Move 1 to the left.
    Move 2 to the middle on top of 3.
    Move 1 to the middle on top of 2.
    Move 4 to the right.

Step 3

    Move 1 to the right.
    Move 2 to the left.
    Move 1 to the left on top of 2.
    Move 3 to the right on top of 4.

Step 4

    Move 1 to the middle.
    Move 2 to the right.
    Move 1 to the right.

These steps will solve the puzzle with all four discs being in the right column.

Defeating the giant worm in Edolus

During the mission about the missing Marines, you will encounter a large worm creature. To defeat it, jump just before the projectile acid the worm spits, and attack it with missiles and constant gunfire.

Defeating Thresher Maw in Edolus

The easiest way to defeat the Thresher Maw is after it has initially launched out of the ground to drive off, stay at a relative distance, and drive circles around it while firing. Because of your distance, it will not use its long-ranged attack or be able to cause melee damage. It will go back underground after a time or certain amount of damage is inflicted and will change the location it pops up. Repeat the circular attack to get away undamaged.

Defeating Saren (before resurrection)

Use your rifle and strafe to avoid his rocket fire. Alternately, use the following trick to defeat Sarren without fighting him the first time in the Citadel. If you have your Charm or Intimidation all the way up, use the new chat options. You will eventually make Sarren kill himself.

Defeating Saren (after resurrection)

Have your crew and yourself use biotic powers everytime Saren stops to shoot (usually when he is hanging on the wall). Only do it once when he stops, otherwise you will be wasting abilities.

Reversed Earth

Once you have landed on Luna, Earth’s moon, look for the view of Earth. When you zoom in on Earth, noticed that its image is reversed. For example, Florida is where California should be and vice versa.

“Scholar” achievement codex locations

This achievement requires that you locate information on all primary Alien: Council Races, Extinct Races, and Non-Council Races.

Aliens: Council Races

    Asari: Speak with Captain Anderson after the first meeting with the council.

    Salarians: Speak with Captain Anderson after the first meeting with the council.

    Turians: If you miss it at the beginning of the game, you can get it by speaking to people about Specters and Saran. Otherwise, it should appear after your first encounter with Ashley.

Aliens: Extinct Races

    Rachni: Speak with the VI Avina near the Consort Chambers/Krogran Statue about the Rachni wars.

    Protheans: Speak with Captain Anderson and Nihlus on the Normandy at the beginning of the game in the Communications Room. This is your only chance in the game to get this codex. If you miss it, you will not be able to recover it later in the game.

Aliens: Non-Council Races

    Batarians: After you become a Spectre, speak with Captain Anderson about his Spectre activities at the Docking Bay.

    Elcor: Speak with the diplomat Calyn in the embassy. He is located at the end of the hallway to the right of the Embassy Clerk next to Udina’s office.

    Geth: While on the mission Eden Prime you will receive this codex automatically.

    Hanar: Speak with the Hanar Shopkeeper at the Emporium.

    Keepers: Speak with the VI Avina in the northwest part of the Presidium. She is very close to the Preaching Hanar and C-Sec Turian whom are arguing.

    Krogan: You get this automatically by entering Choras Den. A scene will play showing the Krogran Wrex.

    Quarians: Speak with Garrus in the medical center after fighting the thugs.

    Volus: Talk to the VI Avina closest to the Embassy Clerk. You will get this by asking the VI why the Volus were the first race to get an embassy.

Easy “First Aid Specialist” achievement

Find a planet that has a Hazard level 1. Stand outside the Mako, and keep pressing [Heal]. Keep track of how many times you pressed [Heal]. If you do not pay attention and run out of Medi-Gel, you could die from the Hazard level.

Easy ally achievements

Use the following trick to unlock all six ally achievements with only three playthroughs. When you start the game, focus on getting all six of your teammates. Choose two of them to play through the game with. Keep those two until you complete the majority of the game. You will get the ally achievement for the teammate you recruited first. After you get it, replace that teammate with another one as soon as possible. After the next assignment you complete, you will then unlock the ally achievement for the second teammate.

Easy skill achievements

The quickest way to get the skill achievements (Lift, Sabotage, Warp, etc.) is to stand outside the Mako and use it for a target. Do each skill with your current character 75 times to get the achievements for each one. However, there are two things to note. First, Neuroshock does damage to the Mako. When you see it beginning to smoke, you must repair it. Second, AI Hacking does not apply. You will need to actually hack 75 AIs or hack a few repeatedly before you must destroy them. The best way to get this achievement is to play the mission where you must go to the Earth’s moon, or “Luna”, and stop the AIs in the training facility. Save the game before you go into one of the bunkers, and keep hacking them until you are finished, or reload and play again.
