Slaughterhouse

Zone 1 - Descent: Run down the stairs, roll to collect the Lamp. Continue down, kill the Brawler, then throw the Lamp at the Greaser. Roll to collect the Bust. Go right, throw the Bust at the Shield Cop. Crush the next Brawler with the door and reflect a bullet at the Suit to clear the zone.

Zone 2 - Screen Time: This is the first camera encounter. To avoid triggering it: lure the Brawler into the starting hallway, then jump and swing down so its body doesn't trigger the camera. Roll past the camera located above the upper left TV screen (near the red wire). If you fail, the TV will turn on, and a gate will block your progress. You can restart the section. If you trigger the camera, Leon will speak to you and then shoot. Dodge his shots by watching the reticle's brief pause before firing.

Zone 3 - Conveyance: If Leon was triggered, he will shoot at you in subsequent zones. To avoid this, restart the level. Go right, reflect a bullet at the Suit. Kill the Greaser behind him. Grab the Lamp, break the door to kill the Cop, and toss the Lamp at the Suit. Roll to grab the Smoke Bomb. Break the floor and drop. Use the Smoke Bomb to kill the Shield Cop. Grab the Molotov and go right. In the next room, throw the Molotov at the Greaser, then reflect the Suit's bullet back at him.

Zone 4 - Under Pressure: Flip the Lever by the laser field and drop. Grab the Smoke Bomb. Wait for the Presses to lift, then throw the Smoke Bomb at the Cop. Kill the Cop and collect the Bottle before the stairs. Go right, reflect a bullet at the Suit below. Throw the Bottle through the lasers at the Brawler, then roll through the lasers. Wait for the next Presses to lift, run along the conveyor belt, and roll through the next set of lasers. Pick up the Sticky Bomb and throw it at the Greaser on the other side, then detonate it. In the next small room, smash one of the two Greasers with the door, then kill the other. Grab the Sticky Bomb. Wait for one of the three Shield Cops at the top to pace left, then throw the Sticky Bomb through the ceiling. Detonate it when he walks back to the others.

Zone 5 - Explosive Energy: Go right, hit the Shield Cop twice to push him back, likely crushing him. Wait for the Presses to lift, then charge the Greaser (or let him come to you to be crushed). Rush up the stairs and kill the Suit. Turn left and burst through the door to kill one of the two Suits in the next room.
