For the Pacifist trophy, you must not kill any Zurks with the flashlight during this chapter!
B-12 Memory
Keep heading through the sewers until you reach the section where Momo has to manually lift the door. Proceed into this tunnel and jump onto the walkway ahead.
Take a left to head into a brightly lit hallway. Follow it to the right. Take the first left just past some Zurk pods on the wall. You’ll then have to quickly run through a handful of Zurk pods on the ground.
Jump into an open pipe in the wall on the left side. At the end of the pipe, you’ll find the memory on a railing overlooking an open area in the sewer.
B-12 Memory
As you progress through the level, you’ll come to a room infested with Zurks and eyes watching you from the walls. Just past this room, you’ll have to jump onto a pipe. Do so then turn left. Follow the pipe then jump to the smaller one on the left.
Follow the path up some barrels and through a tunnel to find the memory.
Scratch
When you come to a large room with two terminals on either side of a locked door, use both terminal to open a door. Head up the flight of stairs. A wooden board will be on the ground next to a pile of barrels. Scratch it!
