Map of Contamination

Letters in italics refer to marked spots on the map. Sector, thing, and linedef numbers in boldface are secrets which count toward the end-of-level tally.

Secrets

1. In the room after the first vent filled with toxic gas, there is a switch tucked into the eastern pillar. Pressing it will unlock a nearby alcove with a super shotgun and twelve shotgun shells. (sector 1317)
2. In the area with the switch that temporarily opens the gate north of it, go northeast from where the switch is and find a big, brown crate. Inside of it, you will find a soulsphere. (sector 660)
3. In the gigantic area with four teleporters and slime at the bottom, drop down and go towards the center of the area. You will find a megasphere there. (sector 835)
4. After escaping the slime floor from secret #3 by using the stairs east of the area, go north until you will find a door next to another big area. Behind it is a room with a crate right next to more slime. Inside of this crate is a partial invisibility. (sector 1195)
5. Far east of secret #4, in a vent where you get ambushed by monsters in a cache behind venting fans, if you take a look at what's on the other side from the middle fan, you will notice a switch. Shooting it will give you access to a berserk pack, a box of bullets, and a medikit. (sector 1612)
6. In the big area with the big teleporter, west of the area with secret #3, there is a venting grate on the northern wall, east of the teleporter. If you manage to jump into that vent, you will find a rocket launcher protected by Hell knight. (sector 1570)
