Tess is back after the events of The Cargo, the weather's bad, and it's time to hit the road. Before you head out into The Outskirts, though, there are a few collectibles to gather up.

Optional Conversation #1

At the very beginning of the chapter, Tess will look out of the window, prompting an Optional Conversation opportunity. Speak to her to check this off.

Artefact #1: Tess' List

Before you follow Tess out of the room, go back to where Joel was sleeping and pick up the Artefact named Tess' List on the top of the side cabinet.

Follow Tess through the hole in the wall and interact with the generator on the other side using the triangle button. You need to power this up by hitting the triangle button when the icons overlap. It should take three tugs to get started. Once it's fired up, press the green button on the lift and head down.

Artefact #2: Patrol Routes Map

Immediately after getting off the lift, look to your right where there are some boilers against the wall. You'll find the Artefact named Patrol Routes Map on the ground.

Crawl through the hole in the wall and then go up the ladder. Once you reach the top, you'll need to push triangle to remove the blockade covering the hole in the ground.

Once the patrol has cleared away, push forward into the rain and through the flood. You're heading for a truck's trailer on the horizon. Climb up onto its rear and walk through the trailer, triggering a cutscene where all three of our heroes are captured.

Once you've regained control, follow Tess' lead and make your way through the sewage area while avoiding the spotlights. Remember to keep low when you're told to do so, and sprint when required. You'll reach a point where your progress is blocked by some guards, so hide behind the wall and then head around the outside.

Fall into the waterlogged building, and head directly ahead into the next room. Then use the ledge to your left to climb up. Before exiting this building, look in the lockers directly opposite for some supplies. Then exit through the doorway.

You'll be at the bottom of a big rubble hill. Walk up it, then crouch behind the fence on the right to avoid detection from the enemies. Climb up the stairs when the opportunity arises, then drop down into what looks like an abandoned barber shop. To the right is a garage door you can open by tugging the large metal chain. Be sure to climb through the window and search the office next door for supplies first, though.

Once you're back outside, you're going to find yourself being hunted by more enemies. This is where your brick tossing skills will come in handy. Crouch down and sneak from the police car to the tank and then into the building. Toss a brick to distract the guards and slip into the next room. Use the cover to get to an abandoned trailer, and jump off it to the right.

Ahead is a big hole. Fall down into it and turn on your torch with R3. Then climb into the sewer pipe and follow the route around. You'll eventually find yourself in a big basement. Take the staircase up.

Crawl through the hole in the wall and overhear what the guards are saying to each other. They're clearing out, which means if you just sit tight for a few seconds, you'll be in the clear.

Cross the building into a corridor. There's a big open doorway on the left, opposite a tunnel. Go in this big room on the left first and scavenge all of the supplies you can find. Then head back up the tunnel and into the sewage pipe. Follow the pipe left into some waist-high water, and unlock the gate at the end to reach Downtown.
