Map of Corrosion
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.


Take the shotgun and berserk pack then step outside to kill some waiting demons and imps. Head west and south past some zombiemen to a door and open it to find a demon (or Hell knight on Hurt Me Plenty (HMP) skill level or higher) guarding an armor, then press the satyr switch here to open a wall to the east that leads outside to a nukage pool. Open another door on the east side and kill two demons waiting behind it, then go up the steps to find another demon (or knight on HMP or higher) guarding a lion switch - approaching the switch closes a set of bars behind you, and pressing it opens a chamber to the west with imps/chaingunners. Go inside the chamber to find another lion switch and press it, kill two more imps/chaingunners that teleport in then go outside and walk north to the red skull key.

With the red key, kill the imps that are released to the south then go back to the starting point and press the lion switch on the north wall, which will open the walls on either side to reveal two spectres (plus imps on HMP or chaingunners on Ultra-Violence (UV) and Nightmare (NM)). Press a second lion switch inside this compartment to open the door to the south-east, pass through it and fight through some demons and shotgun guys to reach another door, which has a knight behind it guarding the exit switch. Watch out for more imps, plus a second knight on UV and NM, that are released behind you when you open the final door.
