Walkthrough

Map of Air Cleansing

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. Head to the west side of the main area and push the wall with yellow triangles to find a soul sphere. (sector 0)
2. Flip the switch in the northeast room, then look northwest to see a shotgun guy in an alcove. In his alcove, you can lower a wall to get a box of rockets. (sector 282)
3. Open the blue door and climb up the crates you see, then use the wall with orange triangles to find a megaarmor. (sector 557)
