MAP22: Habitat (TNT: Evilution)

MAP22: Habitat is the twenty-second map of TNT: Evilution. It was designed by Christopher Buteau.

Secrets

 * 1) Walk straight through the wall directly behind you at the start of the level to access a short hallway leading to a soul sphere.
 * 2) Picking up the soul sphere in secret 1 registers a second secret.
 * 3) After picking up the soul sphere in secret 2, the large crate in the starting area lowers for a short time, revealing a switch. Flip the switch before the crate raises again and a hole will open in the corner. Drop into the hole to get the BFG 9000.
 * 4) Walk through the falling nukage at the beginning of the level and a lift will take you down to a room where a chainsaw is visible. Open the northern green wall to access a brown tunnel system. When entering the tunnel, you will hear a door open. Return to the previous room and get the now-accessible chainsaw. The room the opens upon picking it up is tagged as secret.
 * 5) Once inside the tunnel, follow it to the east until you reach a fork. Go right, then left, and then straight through the next intersection. A wall will open up to the left just ahead of you. Go through this green hallway (A) and follow it to the end, where you'll arrive in the main tunnel system again. Once in the main tunnel, go right, and the wall in front of you will open. Continue through this second green hallway (B) until you see a narrow passage in the left wall. There are some health bonuses inside.
 * 6) Inside secret 5, there is one wall that stops just before reaching the floor. Walk straight through it. A lift with a red skull key (keycard in ZDoom) on it is inside; it is triggered by entering secret 5.
 * 7) On the opposite side of secret 5 is a third green hallway (C). If you entered hallway A, a connector will have opened between hallway C and a fourth green hallway (D). There are several armor bonuses and a yellow door in hallway D, though the connector itself is tagged as secret.
 * 8) Exit green hallway C through the eastern entrance. This opens another secret connector between hallways A and B.
 * 9) Behind the level exit is a red door. If you got the red skull key (keycard in ZDoom) in secret 6, open it and step through the teleporter to be taken to the bottom of the exit pit. Get the combat armor and go back through the teleporter, which triggers this secret.
