After choosing your character, you wind up in your hotel room. Use the Left Thumbstick to move and the Right Thumbstick to look. Head into the bathroom for a Medium Medkit. Look at your mini-map. The white dots tell you where you need to go, so head to the door and open it. In the hallway, go left first, into a nearby room. Here you'll find some things to open up and loot. Get used to this "explore and loot" gameplay. You'll benefit greatly by finding more and more items in out of the way places. Now follow the white dots, checking the luggage as you go for more items.
When you get to the end, enter the room to your left and turn on your flashlight. The icon that pops up shows how much energy you have left in the light. It recharges though, so simply turn it off when you don't need it. After scavenging items, use the next door. It's locked, so you'll have to bust through it. Hold down on the Right Thumbstick and a line will start moving up and down. Push up on the Right Thumbstick when the line is in the middle of the large bar to do the most damage. Keep doing this until you break the door open.
Keep going until you reach a set of double doors that are barricaded from the other side. You'll need to head out onto the balcony. After the short cutscene, move to the elevator shaft and open the hatch on top of the elevator. Hop in and another cutscene pops up. Crouch to get out of the elevator once the doors open. You'll eventually turn right and head down a hallway. Shortly after doing this, though, zombies come from the rooms up ahead. Turn around and head back the other way, through a set of doors that are now open. Run far enough to trigger a couple of cutscenes that end this quest.
Blood on the Sand
After the cutscenes, you wake up in a hut with a bunch of other survivors. In the bathroom you'll find an energy drink, although it's really unnecessary since you have full health. If you look on one of the boxes near the bed, you'll find your first collectable: the Banoi Herald excerpt #1. There's a woman named Jeannine talking to a guy named Wayne near the exit. If you walk past her, she gives you the next quest. Use the door and Wayne will tell you to pick up a weapon before you head outside. Grab the paddle next to the door.
Once outside, you'll find yourself having to fend out several zombies. Use the Right Trigger to swing the paddle, and use the Left Bumper to kick. Kicking has several advantages. For starters, it doesn't degrade your current weapon, since you're obviously not using it. It also tends to knock zombies down, where you can continue kicking them until they die. Finally, it uses up no stamina, meaning you can just cram on that button as much as you want. Still, the paddle does more damage, and there is no shortage of paddles around, so let them have it. If a zombie gets on you, you'll have to press the Left Trigger and then the Right Trigger to get him off. Kill all of the zombies attacking Sinamoi to end this quest.
Passport to Life
Talk to Sinamoi to get this quest. After doing so, remember to put a point in one of your skill trees. You can also talk to Steven in the back of the hut for a side quest. Follow the white dots to the bungalows. There are plenty of zombies here that look dead until you get close. When you finally get to Sinamoi's bungalow, you'll notice a guy, Ted B., in the pool. You can talk to him, but nothing really happens.
Inside the bungalow you'll immediately run into a zombie. There's a locked door you need to bust open. After that, check the bathroom for one last zombie, then pick up the nearby lifeguard keycard and head back to Sinamoi. Don't forget to get the Nail'd Mod from him after completing the quest.
Talk to Sinamoi again to get this quest. You'll need to head down the beach towards the Lifeguard Tower. On your way, you'll come across a guy trapped in a truck. Kill all of the zombies surrounding him and he'll get out and lead you into the nearby building. In here you'll find some loot and a collectable, but there's also a Workbench in the back. Here you can repair and upgrade your weapons, and even construct new ones using the proper materials.
Keep going along the beach. You'll undoubtedly come across a new type of zombie: the Infected. These guys are fast as hell, but they scream loudly when they see you, so you'll know when you need to start looking around. When you finally get up to the lifeguard tower, kill all of the zombies, but don't use the keypad that opens the garage door yet. Instead, place a propane tank or two in front of the door, and then equip a weapon you don't mind throwing, like a small knife. Now use the keypad.
When the door opens, you'll be presented with another new type of zombie: the Thug. These guys take a lot of damage, and they also deal a lot of damage. If they hit you, they'll knock you down. Fortunately, they're also very slow. Aim at the propane tank you've placed, and when the Thug is near it, throw your weapon at it. The ensuing explosion should be enough to kill the Thug outright. Now enter the tower. In the garage you'll find another Workbench. Clear out the lower floor and the roof, then contact Sinamoi on the radio to end this quest.
To Kill Time
This quest actually consists of two side quests. You'll need to help Mike and Dominic with their respective tasks. You'll find Dominic on the roof with you, by the ladder leading up to the antenna. He gives you the On the Air quest. Mike is just outside of the lifeguard tower, by the railing and a pile of bodies. He gives you the Ashes to Ashes quest. Also, don't forget to speak with Hank in the garage. If you get four car parts from nearby wrecked cars and give them to him, he'll fix the truck up and you can drive it. It's a lot faster and safer than walking everywhere.On the Air
Head up the road towards the lighthouse. There are plenty of zombies to kill on the way. After a while, you should notice an area on the right side of the road with white paving. There are three vehicles here. You can drive one of them, the truck, if you want. Once at the lighthouse, walk up to the guy named Colin. He'll instruct you to follow him into the lighthouse. Once inside, head to the top of the lighthouse and talk to James. You can now talk to the people around here for side quests. To move forward with this quest, though, you'll need to talk to Darvin.
Once you've completed his quest, he lets you into the "warehouse", which is just a storage room with a Workbench and the signal amplifier. Pick it up and head back to Dominic to finish this quest.A Ray of Hope
Talk to Darvin, who is standing in front of the warehouse door. You'll need to accomplish his side quest to get into the warehouse, so head over to the golden bungalows area. When you get to Marcus, you find him in a fenced-in area beset by zombies. Kill the zombies and he'll send you off to fix the other transformer. Once you get there, head downstairs and turn on all the power units inside. Now head back outside and prepare to deal with two Infected that come your way. You'll face a few more on your way back to Marcus. Talk to him when you get there, get some money from him, and head back to Darvin.Ashes to Ashes
Head to the gas station and talk to the guy at the window. He opens the door. Now head to the back and talk to Dan Mark. Now head out the back and take care of the zombie here. Throw the propane tank here onto the roof and climb up there. You need to drop into the warehouse on the side of the gas station. The problem? There's a Thug in there, along with some other zombies. Your best bet is to toss the propane tank down there, wait until the Thug wanders by it, and then throw a weapon at it while you're still on the roof.
Or you can drop down and do the same thing, but you'll probably take a nice chunk of damage. Either way, clear this area out, remove the barricades on the doors, and turn the power on. Grab an empty canister in here and place it next to the closest gas pump. The game shows you where to put it. Four Infected will show up around this time, so deal with them, then fill the canister up. Once it's full, stick it in the back of the truck that was in the warehouse (or in your own truck) and take it back to Mike to end this quest.
A Piece of Cake
All you have to do here is bring Sinamoi three cans of food. You can find Canned Food in bars around the island. There are two bars on the beach that jut out into the water, and there's at least one more around the bungalow area nearby. You shouldn't have too much problem finding these. You'll probably already have some if you've explored previous to this. They count as miscellaneous items and as such, don't take up space in your inventory.
You now have to get some juice boxes from two gas stations. Head to the first one and clear out the surrounding area. Inside you'll find a zombie and a Thug. However, they don't seem to be able to leave the gas station, at least not in my game. If this is the case for you, you can simply stand at the door and beat them until they go down. Head behind the counter in here for the juice box, load it into the back of a truck, and head to the second gas station.
The next gas station is boarded up, so you need to get onto the roof and drop in from there. Unfortunately, the area around the ladder is covered in a liquid, and there's electricity flowing through it. You'll need to shut off three switches to make it safe. The first switch is in an open shed-type thing right by the gas station. There are a lot of surfboards in here, and you'll find the switch near the back.
The second switch is inside the closed shed behind the gas station. Go behind the shed and hop over the fence. Grab the nearby propane tank and take it to the side door. Kill the zombie and then open the door. Inside there are multiple zombies, including two Thugs and an Infected. Use the propane tank to wipe most of them out, then hit the switch in here. There's also a Workbench if you need it.
If you use the mini-map compass, the third switch is Northeast of the gas station. If you are using the main map, the switch looks like it's Southwest of the gas station. Either way, it's on top of a tunnel that doesn't lead anywhere. The tunnel does, however, spawn flaming Infected indefinitely, so don't waste any time. The bottom rungs of the ladder you need to use are gone, so pull your truck up to it and use that to get on it. Hit the final switch up top and head back to the station.
Kill the surrounding zombies and get onto the roof. Here you'll find a Walker and a Thug. Once they're down, break the glass on the small roof area and drop inside the store. Load your truck up with another juice pack and head back to the lifeguard tower. Put the juice packs in the garage where the game indicates and then talk to Sinamoi to finish the quest.
Born to be Wild
For this you'll need to head back to the hotel. Your objective is a Hotel Security Keycard laying on the ground outside the hotel. Unfortunately, there are two Thugs standing directly over it. Kill them, get the keycard, and enter the hotel. Inside, you'll fight through zombies until you reach a guy named Mike Davies. He tells you to find someone named Ken.
Drop down into the elevator in between you and Mike and continue on. In the kitchen area, you'll start facing more zombies, including a Thug. Keep going until you find yourself inside the walls, with some pipes and a bunch of steam. Infected roam these areas, so be on your guard. You'll soon come to a room with a Workbench. Repair your weapons if you need to. The next door leads to a swimming pool. There are quite a few zombies in here, including Infected. Funnel them into the Workbench room to make things easier.
After a while you'll find yourself going up some stairs. A few zombies rush you from the top, and there are even more zombies as you move along that area. There's also a bar/food shop here though, with some snacks and energy drinks. Bust open the locked door at the end. You'll find Ken in a closet in this next room. He asks you to go get him some morphine from a medkit, so keep going forward.
Fortunately, the morphine is just a couple rooms over. Unfortunately, you'll have to deal with a few zombies and a Thug before you can get to it. Take the morphine back to Ken once you've got it. Unfortunately, it doesn't help much. Head on, through the groups of zombies, until you finally meet up with Mike Davies in the control room.
He sends you off to the nearby server room. There's a Walker and a Thug to deal with when you enter. The largest room also has several Walkers. Take them all down and use the four computers to reboot the server, then head back to Davies. You can now head down to the parking garage. You'll have to deal with a few Walkers, a Thug, and an Infected once you're down there. Get in the truck to leave the hotel.
After the cutscene, you'll be outside of the truck, for what appears to be no reason. Get back in it and mow down the Infected coming your way, then head back to Sinamoi to finish this quest.
Black Hawk Down
Sinamoi sends you out to the wreckage of a helicopter. You'll need to go up to the lighthouse and then work your way down the back of it on foot. There are a few zombies here, but the resistance doesn't really pick up until you trigger a cutscene that introduces you to a new zombie type: the Suicider. These guys like to get close to you and then explode, doing massive damage. Throw weapons at them from far away to take them down.
Soon you'll reach a survivor: Nikolai. You'll have to escort him to a bunker safely. This is pretty easy. The first wave of zombies that attack can't even reach Nikolai, as he stays on a ledge above. Kill them and head on. A few Infected will come running your way when you get close to the bunker. After this, there's nothing left to do but follow Nikolai into the bunker. You'll find a Workbench in there. Head back to Sinamoi to complete this quest.
This is a fairly short quest. After talking to Sinamoi, get in the truck and drive to the workshop. Once there, run over any zombies you come across. There are a few Walkers trying to get into the actual workshop. Once you get out of the truck, however, a few Infected will come running your way. Once the area's clear, the people in the workshop open it up for you.
Only the Strong Survive
Talk to the mechanic. Leave the workshop and the door closes behind you while he works on the truck. You're now stuck out here, tasked with fending off waves of zombies. They are all of the Infected variety, by the way. There's a good chance that trying to go toe to toe with all of these guys will simply get you killed, so I recommend hopping on top of some barrels. It's just high enough so they can't hit you, but you can still crouch down and hit them. If you prefer ranged attacks, there are a couple of ladders to climb that puts you out of harm's way. After about five minutes of this, the mechanic is finished, which ends this quest.
On the Road/Ram on Heaven's Door
Talk to Jin and hop in the truck. The On the Road quest is simply you driving into the city. Once there, head up the steps. In the courtyard just outside the church, you'll see a bunch of Walkers trying to get in and a Ram wandering around. Rams are powerful zombies that like to charge at you or kick you, doing a lot of damage. Fortunately, this one cannot leave the courtyard. As soon as you enter the courtyard you'll notice a propane tank to your right. Use that to defeat the Ram (and the other zombies, if you can). When the courtyard is clear, the occupants of the church open the doors for you.
Talk to Mother Helen and she'll direct to you to a locked door. You need to kill the Thug inside the next room, take the keys off of him, and use the control box in here to turn the bells off. Also, don't forget to pick up the Toxic Mod blueprint laying on the desk.
After talking to Mother Helen, head off towards the pump station. It's pretty far, so get used to wandering through the streets, taking out group after group of zombies. There are also Infected and Suiciders roaming about. If you don't have anything to throw at a Suicider, remember that you can get close to them to trigger their "explosion timer", which lasts for a couple of seconds before they actually go off. More than enough time to backpedal and get clear of the explosion.
When you actually get to the pump station, you'll face a new type of enemy: humans. A gang has taken control of the station, and they're armed. With guns. Rush towards the front door and beat down the guy that comes out as quickly as possible. Grab his gun and let loose on the other enemies, including the ones on the roof. Holding down the Left Trigger lets you aim down the sights, while press Y reloads your weapon. Inside the pump station you'll find more armed bad guys.
You'll move through the station for a few minutes killing enemies. Eventually you exit the station, kill more enemies, and free Antonio, who is trapped in the small building back there. Follow him back up to the control room to finish this quest.
Drop By Drop
You're now being sent out to close some fire hydrants. The first hydrant is guarded by a few Walkers, an Infected, and a Thug. The second hydrant is guarded by a Ram. Also, when approaching him, watch out for flaming Infected that like to come out of nowhere. They can easily surround you here. If you picked up a lot of guns, taking the Ram out shouldn't be a problem. There's a propane tank in the area, by a dumpster, if you need it.
The third hydrant is farther away. When you get there, you'll have to deal with Walkers, Infected, a Thug, and a Suicider. The fourth fire hydrant is guarded by Walkers, Infected, and a Ram. If you go North (using the mini-map compass) of the square that the hydrant is in, you'll find a closed gate. Outside of this gate there is a propane tank, along with energy drinks and other goodies. There's also a Workbench just West of the hydrant.
There's a Ram on the way to the next hydrant. You're better off just outrunning him and leaving him behind. Once you get to the hydrant, you'll have to deal with Walkers, Infected, and a Thug. Close it and go talk to Mother Helen to end this quest.
Way of Salvation
Speak with Joseph out in the courtyard. You'll now have to escort him to the sewers entrance. On the way you'll encounter plenty of zombies, but nothing too challenging. Most of the time you'll need to wipe out the zombies in your path, but sometimes Joseph will just run past them. As long as he keeps running, you can keep running, leaving some zombies behind. When you get to the sewers entrance, don't forget to get the cash off of Joseph, then head inside.
Let the Waters Flow
Head to the ladder and climb it. Up here there are two valves to turn. There are also two zombies to kill. Once the valves are turned, the water stops flowing, so you can climb back down the ladder and cross the broken catwalk. Head up the next ladder and into the control room. Be careful, though, because a Suicider wanders in from the other door. Use the controls to completely drain the main room, then head back there.
You'll have to deal with a new enemy: the Floater. They take a bit of damage to kill, and they like to spit some kind of acid at you. Although it may look like it, they do not explode when killed, so feel free to beat the hell out of them. Kill all zombies in here, including the Infected guy, to update the quest.
After opening the next door, you'll head into an open area filled with zombies and a Floater. The Floater doesn't come up until you get near him, so let the Walkers come to you, clear them out, then approach the middle area and you'll find the Floater underwater. Keep kicking him and he won't even have a chance to get up. Further ahead you encounter another group of zombies, along with a Thug. Kill them and go down the ramp. You'll quickly encounter another Thug, a Walker, and a Suicider.
Keep going until you round a bend and pass an open gate. Shortly after this, keep an eye out on the left side for a Floater that likes to ambush you. A bit after this you enter a room with a Walker, an Infected, and a Thug. There's a door on the left side of this room that leads to a Workbench. The tunnels up ahead have a couple of Suiciders in them. After a bunch of zombie-slaying, you'll finally reach the end.
Head Against the Wall/Supermarket Journey
After heading upstairs and talking to the Mayor, head back upstairs and talk to a man named Josh. Now head all the way downstairs and talk to the guard. He wants you to bring him a bottle of alcohol. If you don't already have some, head up a couple of floor and enter the Mayor's office again. This time, look for a bottle on the shelf. Bring it back down and the guard will let you through.
You're now heading back into the sewers. The water in here is toxic, but you won't be in the sewers for long. Watch out for Suiciders and make your way to the exit. Outside of the sewers, turn the valve when you reach it. On the other side you'll face a few Walkers and an Infected. There are more Walkers up ahead, along with a Floater. In the room after this, four Infected come rushing you.
Soon you enter the actual supermarket, which is filled with gang members. Kill the first punk and grab his gun. There are plenty of armed foes in here, but there's also a ton of healing supplies laying around, so don't fret too much. The thugs soon block your way forward, so you'll have to take a side path, which involves zombies. The first room has a single Walker and the next has a Walker and two Infected. After that you'll enter a room with a Ram. You can try to ignore him and open the locked door, but you'll have to be quick to open it. Sometimes he lets you go, sometimes he doesn't.
The next locked door leads to more thugs. The thugs hiding out in the back areas wield assault rifles, so be careful. They can do more damage than you realize. Once everybody's dead, load the supplies up to finish this quest.
You're back in the sewers again. Deal with the Suicider and Infected. The rest of the sewer area is pretty simple and short, since you've already been through here. However, once you're back in city hall, you'll find that it's been overrun by zombies. Head upstairs and out onto the balcony area overlooking the center square. You'll find a grenade on a zombie up here pretty quickly. Use it to deal with the Ram, Suicider, and other assorted zombies down below in the square.
Work your way around to the Mayor's office. On your way you can man a machine gun that overlooks the street and lay waste to several zombies. You'll soon come to Mayor Todd. Well, Zombie Mayor Todd. He acts like a Thug, so don't get closer than you have to. Once he's down, get his universal key and loot his office, then go back the way you came. Head downstairs, fight off the Infected, and kill the Thug. There's a Workbench in the room with the Thug as well, if you need it. Enter the sewers when you're ready.
This is simply more of the same, though you'll be taking a different way out. There are plenty of zombies to take care of, including Infected, Floaters, Suiciders, and even a Thug or two. Nothing you haven't seen before. Once back in the city, head to the church to complete this quest.
Lady in Trouble
After talking to Mother Helen, head back outside. Joseph is laying on the ground at the bottom of the stairs, so talk to him. You're going to have to head back into the sewers. Again. Fight your way through the city streets for a while. Nothing significant happens here. You eventually come to a manhole in the middle of the street. Use it to descend into the sewers. This sewer segment doesn't take too long, though there are a few Floaters and some Infected to deal with.
Once you get inside the police station, you'll find that it's been mostly overrun by infected. There are Suiciders and Infected around, along with the normal zombies. You'll soon reach a point where you start fighting gang members. They are your only enemy until you reach Jin. You'll know you're getting close to her when you fight enemies with automatic weapons. Opening the final door triggers a cutscene. After this, you're automatically placed in front of the church with the truck. Talk to Jin to finish the quest.
Home Sweet Home
After talking to Jin, talk to Mother Helen. Now head back down to the car and hop in. You'll be taken back to the resort. Drive to the lifeguard tower and talk to Sinamoi. He sends you off to the hotel. All you have to do is drive there and use the front door. This triggers a cutscene. After it's done, head back to the lifeguard tower and talk to Mike on the roof. He'll make a bomb for you. Now head down and talk to Jin. You'll actually have completed about four or five small quests here.
Get in the truck with Jin and drive to the waypoint. Here, you'll have to get out and protect Jin as you both head towards the bunker. You'll have to hold off Infected two at a time at certain points. When you get to the bunker, clear out the zombies and the Thug and arm the explosives on the door. Head back up the stairs and wait for Jin to approach you. Once the explosives go off, this quest is complete.
Welcome to the Jungle
Enter the bunker and use the Workbench inside if you need to, then head into the manhole. You'll come out in the jungle area. Hop inside the jeep here and drive down to the waypoint. Now you need to get out and clear the zombies from beneath the bridge. There's a Floater here too. After this, simply follow Jin to the village. You can ignore any zombies you pass if you want.
Once you get the quest, head into the canyon. Here you'll fight a few zombies. In the next village there are more zombies, including a Floater. There is a propane tank laying on the ground in the area with the Floater, and there's another one on the first roof you can access. Keep one of these with you. When the Floater area is clear, take the propane tank and carry it until you hit the cutscene. You will be introduced to a new enemY: the Butcher. These guys are fast and powerful. They like to use their arm bones to slice and dice. Use the propane tank to make short work of this one and continue on.
After crossing the wooden bridge, you'll come up behind some men. A firefight will inevitably ensue. Keep working your way down towards the water, but do NOT get overzealous here. Make sure you take everyone out before moving forward. Not only are there more humans than it appears, there are also zombies lurking around. A Floater or two is probably in the water, and Infected like to come out of nowhere. Take your time with this and make your way to the other side of the creek. Here you'll find a working jeep with a weapon crate behind it. Load the crate into the jeep and drive it back across the creek. Load up the other crate that you passed up before and head back to Matutero. Take the crates out and stack them outside of the hut, then talk to Matutero to finish the quest.
Soldier of Fortune
Hop in the jeep and head over to Afran's village. On the way you'll encounter a group of Afran's men in a firefight with a survivor. Wipe them out and the survivor will give you some cash. At the village, take out the two guards in the watchtowers and get on top of the wall. Inside the watchtower you'll find a machine gun. Use it to clear out the area up ahead, then drop down into the village and move on. There are more enemies to deal with, including one inside of the bus in the middle of the village.
You'll fight your way through the village and along the beach houses for several minutes. After the cutscene, you finally take on Afran. He's the guy with the SWAT gear in the top middle of the area you're facing. There are two soldiers on either side up top as well. He takes a lot of damage, but there are a few health items scattered around. Just keep ticking away at his health with gunfire and you'll take him down eventually. Make sure his soldiers are also down, then break open the door. Grab the Phoenix Mod in here, then get on the boat and use it to complete this quest.
King of the Swamp/River Trip
Talking to Matutero deposits you in the general area of Mowen's hut. Head up to the hut and talk to Mowen to start the next quest, River Trip. Now go back to the boat and use it. When you dock again, go to the right and get in the jeep here. Drive through the hordes of zombies until you reach the laboratory. There are plenty more zombies to deal with here, and there's also another jeep. Inside the building you'll find a couple of zombies. Take them out and head through the door. There are scientists in here. Head to Dr. West and talk to him to finish this quest.
House of Science
You'll need to help some scientsits in the area complete side quests before you can move on in the story.Rats in the Lab
Talk to Bob, then step into the nearby decontamination chamber. There are a few zombies to deal with in the next hallway. After they're all gone, head back to Bob to finish this quest properly.Power Slaves
Talk to Will. The white dots on your mini-map tell you to move through the inside of the building. Ignore them. Head outside and after exiting the door keep going forward. You'll be going around the right side of the building (the right side if you're facing it, that is). Eventually you move through a gate and head down a ramp. The warehouse ahead has a Ram inside it, and as far as I can tell, there's no real way to make this any easier. Also, after a minute or so, a bunch of zombies come for you. They're mostly Infected, but there's also a Butcher in there. Take them all out and grab the fuses in the back.
Two of the Walkers in the warehouse raise up when you go to leave. Head downstairs and kill the few Walkers, then insert the fuse into the breaker box in the building down here. You'll face a few Infected on your way back to the laboratory. There are also several Walkers, but you can outrun them if you want.
Man of Faith
Get in the jeep and head towards the waypoint. Once you get there, you'll find that the main gate is closed. There is a side path to the left of the gate that you can use to get into the village. Once there, hop into the arena and you'll have to fight off waves of Infected, usually two at a time. After a few waves, you'll have to take on two Infected and a Warrior, who appears to be a stronger Infected. Once they're all down, get the blood sample from the Warrior and head back to West to finish this quest.
You'll be doing a couple more side quests here.Substance of Matter
Talk to Frank to get this. You'll need to head to a warehouse just behind the main building. On your way you encounter a few Walkers and a Floater. Once inside the warehouse, there are a few more Walkers to deal with. Grab the container and carry it back to Frank, then set it down by the door to finish this quest.Rotting Flesh
Talk to the Scientist in the operating room to get this quest. You'll need to head to a house just up the hill from the lab. Outside this house, fight off the Walkers, Infected, and two Butchers, then head inside. You'll find zombified versions of Nick and John in here. Kill them and get tissue samples from both, then head back to the scientist to complete this quest.
If you are doing this alone, make sure you have a molotov or a grenade or some kind of powerful area of effect weapon. You will need it.
Head back up to Ope's village and talk to him. You'll now have to escort him back to your boat. The first enemy you encounter is a Thug. After taking him down, you'll come across a few Walkers. The next group contains Walkers and a Thug. After this, it's a straight shot to the boat.
In the next area, you'll quickly encounter some Walkers and a Floater. Further on, you enter the village. This part can be extremely hard if you're doing it solo. The village contains a Thug, a Butcher, and a bunch of Walkers, and most of them focus on Ope. The problem? Ope can take VERY little damage. If you have a molotov/grenade, use it on a cluster of enemies. This makes things a lot easier.
After clearing that out, keep going. You'll fight a few more zombies until you get to a bridge. On this bridge, take out the Butcher and two Infected that head your way. You soon come across another smaller bridge, but it's raised. Drop down below the bridge and jump across the gap, then use the ladder to get up to the other side and hit the lever here. Keep going now until you trigger a cutscene.
You'll now have to follow Yerema as she runs down a path filled with zombies. The point is to try and outrun them, but sometimes Yerema will stop for apparently no reason, which means you'll have to stop. Which means you'll probably be swamped by several Infected. Either way, keep going until you trigger the next cutscene. You now have to head down and help Mowen fight off several Zombies, including a Thug and a Floater. This isn't nearly as hard as your fight with Ope against the zombies in the village, so take them out and head to the boat with Yerema.
When you get back to the main jungle area, you'll have to escort Yerema through more zombies. When you reach a metal bridge, prepare to deal with a Butcher and some Infected. The rest of the way back to the lab is pretty barren, save for a few Walkers. Once there, talk to West to finally end this quest.
Hard Talk/Boat Supplies
Go talk to Mowen, then use the boat to travel back to the city. Here you'll have to pick up a package for Mowen and some gas. Head out into the city and before long you'll pass in front of the pump station that you visited previously. You should notice a yellow wheel on your mini-map, which means there's a truck here. Get in it. It'll be very useful since there's a Ram and some other zombies in front of the area with Mowen's package. Make sure you drive out of the far entrance of the pump station though. There are barricades on the street between the nearest entrance and the far entrance.
Once you get to the docks, clear out the zombies and use the ladder to get on top of the containers. The last container you enter will have the package, along with a couple of locked boxes. Get the package and head off towards the gas station. If you're driving, be very careful here. There are a couple of Suiciders wandering around, and hitting one of them will kill you. If you want to go on foot, you can. It's not that far and there's another truck at the gas station. Once there, load the two gas cans into the back of a truck and get back to Mowen. You'll have to carry the cans yourself for the last several meters. Talk to Mowen and use the boat to get back to the resort.
Back in Black
Head to the back of the warehouse. You'll have to fight through some Walkers, a few Infected, and a Thug to get there. There are metal rods behind the warehouse that you need to pick up and take back to the boat. Don't forget that there's also a Workbench and some medical supplies inside the warehouse if you need it. Once you get back to the boat, a cutscene triggers and then you automatically head back to the jungle.
No Time to Talk
Get in the jeep and drive through the zombies to get to the lab. Inside you'll find a bunch of Walkers. Kill them all and use the computer on the table in the center of the last room to free Yerema. You now need the antidote, which is in one of the mini-fridges in this room. It's the one where the door opens all the way when you use it. Now use the radio. Like the prompt says, you will not be able to return to the island once you finish this quest, so be sure.
The Green Mile
After making your way to Titus and talking with him, head over to the cell block. In here you'll find some zombies, including a Ram, though you're better off just ignoring them for now. Make your way up to the cell and talk to Alvaro. Now you have to head to the control room and open the cells. Doing so turns on the alarm. You'll now have to deal with constant waves of Infected, along with a Thug. Turn the alarm off and head up to Alvaro's cell. You shouldn't have to deal with anyone until you exit the cell block, where you'll find a lone Thug waiting for you. Take him down and head back to Titus to end this quest.
Full Metal Jacket
Head to the upper floor. You'll face several zombies up here, including a couple of Infected. When you encounter people shooting guns, don't assume they're friendly. Because they're not. Kill everyone at that barricade and talk to Kevin at the armory ahead. He sends you to another area nearby with a few armed guards in it. Kill them and grab the Master Key on the counter, then go back and talk to Kevin again.
You'll now have to hold off a group of Infected. Use one of the propane tanks in the hallway to help you. After this, a Thug comes out. Take him down, then enter the armory and grab the weapons box. On your way back, you'll face more Infected and Walkers.
This is a simple quest. Head to the kitchen area. The first room has several Walkers. The actual kitchen has some Infected and a Thug. The next door leads right back to Titus, where you can finish this quest.
Head downstairs. You'll know you're about to encounter zombies when you see a propane tank. Use that tank to clear the next room, then continue on. There are a few more zombies to take care of before you reach a room with guards. Take them down and enter the doors on the bottom floor. There are more zombies in here, along with a propane tank. Use it or the other propane tank near the exit door to deal with the Thug, then take the remaining tank with you. There is another Thug in the next room, but don't use the tank on him.
You'll be in another cell block soon. You can't enter the control room from here, so you'll have to head downstairs and work your way up to the other side. Unfortunately, a Ram, a Thug, and some Walkers stand in your way. Use your propane tank here, if you've still got it. There are more zombies and yet another Ram on the bottom floor. The rest of the way to the control room is dotted by Walkers, Infected, a Thug, and another Ram. Once you finally get there, the Voice tells you to go elsewhere.
There's a Workbench just ahead. After this you descend into a sewer area with plenty of zombies. You'll fight a couple of Floaters along with other zombies before you reach a ladder leading back up into the prison showers. A few Walkers later you encounter Yerema and Jin. Follow them into the elevator to end this quest.
Chasing the White Rabbit
Keep going until you reach some zombies. You'll face Walkers, Infected, Thugs, and a surprising number of Rams in these next hallways. There really isn't any easy way to get rid of the Rams, so you might be better off trying to ignore them. Once you go upstairs, you'll come across a Workbench. The next hallways are filled with Walkers, Thugs, Infected, and Suiciders. The last hallway also has a Ram. The next set of stairs leads up to the roof.
On the Edge
You're on the roof now with several soldiers. There's a room nearby with a Workbench and a bunch of medkits. Kill all of the soldiers and a bunch of Infected will start swarming you. You need to move through a fence that was knocked down under the helipad. There's a Thug standing between you and the next cutscene.
The final boss is like a Thug mixed with an Infected. He's fast, but also powerful, and can take you down in just a few blows. If you have any kind of ranged weapon, now's the time to break it out. Other Infected also trickle in, but they aren't too big of a deal. Try to get White to rush you, then get a blow or two in while he's recovering. If you don't have one with you already, use the Workbench to create a modded weapon, so that critical hits do the extra damage. The entire roof is open to you, but it's also open to him. Once you kill him, the game is finished.
