Factory

Outside the Factory: Start by killing two enemies. Jump to the rooftop on the left and search the body to find the Prism Key, unlocking the 'Prism Key' achievement/trophy. Proceed right, jump over boxes onto stairs, and continue until a dead end. Use wall-jumping to reach the roof on the left, then jump across the gap to the right. Alternatively, swing your sword up and right to skip a step. Climb small rooftop ledges to the right, drop from the clothesline, and continue right. Swing your sword downward to break the floor and enter a hallway. Open the door and run to the vault door on the far right, interacting with it to proceed.

Factory Hideout: After a phone call, you'll be introduced to the Factory Hideout. You can unlock the 'Don't Hang Up' achievement/trophy by repeatedly hanging up the phone during conversations, but this is recommended for a second playthrough. Swing your sword to start the level proper.

Zone 1 - Brawlers: Run up the stairs to the right and defeat the approaching Brawler. Head left, smash open the door with your sword to kill a Suit, and then kill a second Brawler. Follow the arrow out of the room.

Zone 2 - Lasers: In the next room, use the roll button (R or ZR) to dodge laser beams. Use your 'pre-cognitive' ability (hold L or ZL) to slow time and navigate a moving laser. Find a Lever on the wall and use it (X button) to turn off the lasers and open the path to the right.

Zone 3 - Climbing: Run right and wall-jump to the top. Cut through the wooden slab at an angle to kill the first Brawler. Angle your next aerial swing to kill a second Brawler to the right, being careful of the laser on the far side. Roll through the laser, then wall-jump up. Use slow-motion to pass the fan.

Zone 4 - The Scientist: Open the first door and defeat the two Brawlers with two swings. Go up the stairs and right to find another Brawler behind a door. Kill him quickly, then head left. Roll through the double laser.
