Chapter 5: Underwater Facility

Head through the doors to trigger a scene. Crawl underneath the gate and smash the 3 wooden crates.

Boost Piers over the gap and hop down by the ladder. Once the blades stop spinning, head through.

Move to the far side of the area, grabbing a wooden crate by a support pillar. Wait for Piers to deactivate the next set of blades. Loot the nearby wooden crate.

At the end of the ventilation shaft, crawl down a smaller shaft to reach a walkway below.

Hide behind the boxes to your right to stealth melee the first guard when he passes, ensuring you are in a crouched position. Waste the other guard.

Pull the lever and call the elevator with the red button to get Piers. Ride the elevator down quickly when you get the chance.

Head through the door at the end of the walkway and defeat the Neo-Umbrella J’avo. Use grenades for groups larger than three and take cover (press the cover button to crouch behind walls or objects) whenever possible. Use the sliding door as a choke-point.

After clearing the room, smash the wooden crate.

Move through the next hall and search the left side before heading through the door to find 2 wooden crates and a metal box containing 40MM Nitrogen Rounds and 40MM Acid Rounds.

Head into the next room, quickly kill the Neo-Umbrella J’avo with RPGs, and grab the wooden crate.

Make your way to the next elevator, which leads to a circular chamber.

Head up to the upper level for more maneuverability and to find 2 wooden crates.

Check the doors and prepare for many enemies, including Napad and a Gnezdo, along with various snipers. Head up to the upper level to take out snipers, but do not stay too long.

Go downstairs and circle the area to buy time. If snipers become a problem, head up again to eliminate them.

After a few minutes, head through the doors when your partner is close and few enemies are nearby. A scene plays afterwards.

Haos Fight: Press the switch. Search the area for 2 wooden crates and 2 wooden boxes.

Flip all four levers at once. Go up to any lever to ride the elevator up. Defeat the J’avo and snipers that drop onto the elevator.

Clash Of Egos: After the scenes, escape by rushing up the ladder and over the catwalk to boost Piers up. Quickly tell him to pull Chris up as well, then proceed.

Jump off the platform and unload on Haos. Quickly rush over the catwalk and slide underneath the obstacle at the end. Immediately recover and climb the next catwalk. Failing this on higher difficulties results in game over.

Proceed over the catwalks. Haos will attack again; unload on him. Hold onto the platform as Piers unloads on Haos.

Make your way to the elevator up ahead.

Second Haos Fight: The outer ring of the arena contains 2x, 3x, 1x, 1x, 2x, 3x wooden crates (counterclockwise). Stay 30+ meters away from Haos. Unload machine gun clips into him with small bursts.

When out of ammo, grab your rifle and shoot Haos repeatedly, preferably in the head. Other parts will also work. If you run out of ammo, use any gun except the shotgun.

After defeating Haos, head through the doors and collect 40MM Acid Rounds and 12-Gauge Shells on the floor.

Move through the hall. Crawl underneath the door as Haos attacks again. Press A (Xbox) or X (PS3) while crawling to go faster.

In the second cabin, shoot Haos's hand once or twice, move past it, and slide underneath the shutter. Repeat this process until you reach the last shutter.

As Chris, climb up when Piers holds the very last shutter open for you.
