Walkthrough

Map of The Demon War Machine

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. After teleporting out of the southwest arena, lower a wall to the north and head north to a secret area with a box of shotgun shells. (sector 330)
2. At the south end, use the north side of the middle column to lower it. Ride up and flip the west switch, then the east switch to lower. The east wall will also lower, revealing an energy cell, a soul sphere, and stimpacks. (sector 344)
3. At the normal exit, use the switch behind the evil eye to the north, then quickly descend the steps and take the north lift. Open the wall and follow the path to get to the secret exit. (sector 151)
