Altar Corridor
Turn around and leave the broken bridges behind to enter a large circular room and scan the upper level to shoot a Serpent Emblem before pulling the levers and entering the Catacombs.
Catacombs
Head into the catacombs and break the urns as you go to reach some stairs. Before heading up, open the two tombs on either side for 2,000 Skill Points and a very unhappy snake. Head up the steps and follow the path while looking for the tomb on the left hand side that has the Assault Rifle RN and an urn of ammo nearby.
As you head down the steps you will trigger a trap of spinning blades. You need to Dash (L stick + X or L stick + B) and then hit L1/LT just before your reach the blades. If you don't want to risk death, get on your butt by holding L1/LT and hitting X to get down and then crawl forward. Continue to hold L1/LT, instead of crawling forward, and use the blades as a defense against the incoming enemies. When they are dead, crawl forward and continue along the path until you reach a wall of fire.
Catacombs: As Leon
- Vault Helena up the broken ladder and while you wait for her to turn off the flames watch your back for zombies. If you want to get a unique medal, you need to kill the zombie off to the right that is turning a crank WITHOUT sending Helena through the tunnel.
Catacombs: As Helena
- Crawl through the tunnel and when you exit the other side, drop down and kill the zombie turning the crank.
Once the flame has stopped, cross the bridge and examine the doorway with serpents and when you can, place the ring to start a wave of enemies.
Remember that flame trap, well you can use it too. Head to the right and start the crank to ignite the flame. You will probably only want to crank it three times to kill the approaching zombies before ones behind you start to appear. Switch to an Incendiary Grenade and take them out and switch back to the crank for another 2 goes before you check your back again. Eventually, they should all die and a scene the indicates the door is unlocked will occur.
Follow the path into the water and stick to the right to find a dry area with some urns and a Serpent Emblem inside a tomb. Proceed forward to a gate and vault Helena up by the tomb.
Catacombs: As Leon
- Rush back to the land area, because zombies in water are hard to see and kill. When you reach the land the zombies should come in behind you. Kill them and wait for Helena to open the gate.
- Just as you reunite with Helena you will be split up again and she will be in trouble. Pull out your Sniper Rifle and cover her until all three zombies are dead and then use the nearby crank to lift the gate for her.
- Continue and slide under the spinning blades and you will be stuck between two traps. Shoot the crank operator off to the left and examine the new crank machine, which will begin a wave of enemies behind you for the crank.
- Once all the enemies are dead and you have the crank, use it to reunite with Helena.
Catacombs: As Helena
- Crawl through the tunnel on your back and be careful of zombies in the tunnel with you. When you exit the other side, turn the crank and let Leon through.
- Just as you reunite with leon you will be split up again and surrounded by enemies. Rush to land and turn around to take out the enemies.
- Once you are clear, turn the crank for Leon. Wait for Leon to turn his crank and then make your way to the tombs, with 5,000 Skill Points and a snake.
- Wait for Leon to kill the spike turning zombie and then advance. Jump on a container, where you can snipe from to support Leon.
- When Leon grabs the crank and opens your gate, head through and kill the zombie on your side before opening the final gate.
Before heading to the double levers, you may want to backtrack down Helena's path, if you were not playing her, to grab any loot that dropped, and two tombs that can be opened for 5,000 Skill Points and a snake.
Cavern
The enemies in this cavern continue to jump down from ledges above, so there is no point in sticking in one area too long.
Follow the linear path and lower the drawbridge, when you have a chance, and continue forward. You will eventually come to a fight with a Shrieker and some Bloodshots that you should use any grenades on.
When you start to pass over wooden bridges, look ahead and check if there is a Whooper there. If there is, set a Remote Bomb down at the end of the bridge and snipe him, causing him to barrel down the bridge and into your bomb.
When you finally reach the dead end, vault Helena over the gap.
Cavern: As Leon
- As soon as Helena is across the gap, the platform collapses and she is attacked by some zombies. Snipe them off her before they drag her down into oblivion and then cover her as she makes her way through the area.
- When the Whooper appears, take a few shots on him, but watch your back for a few zombies that drop in on you. Once you have dispatched them, cover Helena again until she lowers the bridge and you are reunited.
Cavern: As Helena
- Crawl up slowly, but only out of reach of the zombies, so that when you reach the top and fall down you are not swarmed by zombie.
- On the other side, equip a Remote Bomb and set it down in the path of the Whopper that is rushing your way. Kill it and then continue.
- Zombies will come from behind you, which turn into Bloodshots. Keep moving forward and jump over the gap to the drawbridge and turn the crank when it is clear.
Hop down and cross two narrow bridges and then look in the distance for a Serpent Emblem. Shoot it, kill the enemies that drop in the area, and contune onward. Keep heading down the linear path until your reach a set of twin cranks that will need to be cranked, after you kill a wave of enemies that inturrupts you.
As the bridge lowers, the structure you are on collapses and you land on not-so-solid ground. Dash through the area, avoiding enemies, until you reach a boulder that you and your partner need to push to jump across to solid ground.
Underground Water Channel
The ground might be solid, but the water from above comes crashing down and sweeps you off your feet and down a tunnel. When you finally exit the water tunnel, you are stuck underwater with no room for air.
Follow the path and stick close to the ceiling to look for air pockets. As you make your way through the area you will start to pass corpses, some of which spring to life and drain your air supply. Backtrack to a known air pocket, to be safe, or continue forward in the hopes of another air pocket soon. Either way, make your way to the end of the area, using the navigator if needed, and use the partner action to escape.
You are not safe yet though. The Brzak drags your team underwater for a few QTE's.
Helena QTE's'
- Info Coming Soon
Leon QTE's
- Square + X/X + A
- L Stick
- R1/RT
When the Brzak finally spits you out, Leon and Helena are split up again.
Underground Water Channel: As Leon
- Swim through the area until you reach a gate and wait for Helena to open it.
- When it is finally open, start to swim toward the destination marker and Brzak will come after your from behind. Tap X/A as fast as you can to give Helena time to shoot it and save you. Do this three more times, along with a quick fight from a zombie, and you will reach the shore.
Underground Water Channel: As Helena
- Info Coming Soon
Reunited, break open the nearby urns and head back down Helena's path to grab 5.56 Ammo x2 and shoot the Serpent Emblem, if you did not get it as Helena before, in the tunnel past the bridges.
When you are ready, return to the area where you got out of the water and use the Partner Action to push the gate and start the boss battle.
Boss: Brzak
The Brzak will charge you with its mouth open, exposing its tongue. Shoot the tongue while also picking up 9mm Ammo, when needed, and continue to attack him.
When Leon mentions to watch out, prepare to hit the QTE (Square + X or X + A) to dodge an attack.
Continue to fire until the screen slows down and the camera tilts up to a TNT Barrel. Shoot it to finish the battle and the chapter.
