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.

2. Enter the central section from the southeast path and quickly run to the southwest path, going all the way to the south. Ride up to get a chainsaw. (sector 226)
3. Get the blue key and enter the north compartment. Head west and to the area with the green armor. Approach the armor, then run east and north into a small alcove. Take the lift up and follow the path to a plasma gun. (sector 211)
4. Open the blue door to the maze section, then head east all the way, but just before the last corner, lower a wall to the south to pick up a light amplification visor. (sector 18)
