Resident Evil 6 - Chapter 4: Ada’s Demise

Aircraft Carrier - Forward Hanger

You will enter the hanger where Chris and Piers exit after gathering the three passcodes. Head forward and kill the unaware J'avo and the head left to break open a crate before turning around and going the other way.

Continue forward slowly, stealth killing any J'avo you come across, and then examine the door opposite the one Chris and Piers open to activate the passcode locations.

Passcode A

Turn around and take cover on the oppsoite wall, where you enter Chris' passcodes, and wait for the J'avo to enter the area and turn around for a quick stealth kill. You can now gather the Passcode A via your device, leaving it for Chris and Piers to get later, and then back away as a Rasklapanje drops down from above.

Defeat the Rasklapanje and J'avo that enter the area before you advance.

Passcode B

Head through the door, down the hall, and take the left into the mess hall. By now, the Rasklapanje may have revived and need to be killed again. Enter the door on the other side of the mess hall and follow the path to the next closest passcode inside the room with the one-way door.

The J'avo will likely see you, so kill it and try to collect the Passcode when a Rasklapanje eats it and runs off. Rather than go after it, wait for it to return to reclaim Passcode B.

Passcode C

From the room with Passcode B, take a left and then hug the right wall to a room with 5,000 Skill Points, the Bear Commander, and a First Aid Spray in the bathroom. Exit the area and take a right and follow the path until a pipe ruptures and quickly hit X/A when prompted and then defeat the other Rasklapanje that drops down behind you while the fire is put out.

Head down the path and be ready for an ambush of J'avo and Rasklapanje. Take out most of the enemies with the Bear Commander's Explosive Round and then finish up any stragglers before entering the room with the machine-gun J'avo and killing him for Passcode C.

Leave the room and head right down the hall, back to the stairwell, and take it up to the beginning where you can input the codes. Two Rasklapanje wait on the other side, so use the Bear Commander's explosive rounds to take them out and then head up the stairs for a crate and grapple upstairs. Wait for the dialog to finish and then examine the elevator button.

Aircraft Carrier - Bridge

Grapple up and enter the bulkhead door, just as Chris and Piers arrive, and then slide under the closing door. Grab the Green Herb in front of you and head up the stairs. You should see a bunch of J'avo hanging out in a room; this is the indicator for the start of an area that stealth = trophy/achievement.

Head through the open doorway nearby and quickly dash around the central object and grapple to the upper level from the back side of the area. If you get caught in the light, you will be detected and surrounded.

On the upper level, shoot the Serpent Emblem and head inside to a vent, where you get to watch Chris and Piers fight it out below. Exit the duct and follow the path down the corridors, ignoring the side rooms as you can easily get seen by the J'avo inside. Keep moving, carefully, until you reach the control room.

Wait for the Gnezdo to start walking by the far side of the room and then rush in to hit the button and jump outside. The open hatch leads to another area with spotlights, so be ready to run.

Hop over the first obstacle and then make sure you are as close to the far wall as possible and crawl into the vent when prompted (if you are sighted you'll have to quit to the main menu and restart the whole section, since a checkpoint won't work).

Hide behind the metal sheeting until the light passes and then move forward to the next metal sheeting and wait again. When the light passes, get out and dash around the other side to grapple upstairs.

Head right and break open the crates and then be careful walking left. Take cover on the left wall and peek out quickly to get aim on his head and then let yourself go back into cover. When you are ready, peek out to headshot the bastard and then go around the side. Duck under the windows to avoid being spotted by the J'avo and move to the ladder.

Inside the room, there is a vent and two spider-like Noga-Trchanje. Hop onto your back and wait for them to stop moving before shooting them with your Crossbow and then crawl across the battle below to the objective and continue to a cutscene.

When you have control again, head downstairs and jump into a hatch where a J'avo patrols. Wait for it to walk away from you and then rush in for a stealth kill. CHeak the area for a crate and Serpent Emblem and then take the elevator to 5.56mm Ammo x2 and head for Carla's corpse.

Aircraft Carrier Interior

Start by breaking the crate and shooting the Serpent Emblem near the hatch before you jump down. As you head forward, Carla will start goo her way through the ship's interior. Dash forward and take a right all the way down the stairs and open the hatch below.

The next room will likely have a Carla Spore, which is slow and deadly. Break open the crate and then shoot the glowing bulbs on the door to advance. Head down the hall, turn right, and enter a room with a Green Herb. Take a right again and you will be grabbed by the wall and have to rotate the L stick to get free. Do this twice and then open two bulkhead doors.

The face in the upper left corner of this room will lunge forward to attack you, so stay away. Shoot it with the Bear Commander and when it stops attack rush under it into the doorway and then turn around to shoot a Serpent Emblem.

Shoot the Carla face in the wall to run past and then hit the blue canisters on the floor with a quick shot to prevent a Carla face from eating you as you turn the valve to exit the room.

Kick open the crate and turn the corner and be prepared to dash. Start by holding up on the L stick as you dash and the quickly rotate the L stick when the wall grabs you. Now hold down on the L stick and continue to dash over obstacles. If you are unlucky, a second wall will grab you and likely cause death. When Ada grapples out and the slow-mo activates, shoot the blue canisters to prevent death.

The glowing bulbs nearby drop ammo again, so take a second to destroy them and then continue.

Carla Spore

Equip your Bear Commander and use any of the rounds you have left to take out the eyes of the Carla Spore and it's main attack.

The object is to create a hole and then shoot an explosive arrow through the gap before she regenerates it to explode the massive amount of nitrogen canisters behind her.

As Carla Spores walk around the room trying to prevent you from attacking, switch to your Pipe Bomb arrows and toss them into the same spot on Carla's face to create a hole.

Hopefully, you have a large amount of ammo left, but if you find you're running low, shoot the glowing bulbs throughout the room to get more ammo. When you do manage to explode the canisters, head forward and hop on the elevator.
