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.

Essentials[edit]

At the very start of the level, the exit is blocked. Head left and pick up the super shotgun. Continue down the corridor into the northwestern part of the level, where you will find a switch guarded by two double chaingunners. Proceed to the southern section, where you will find green armor and a plasma zombie. From there, head to the northeastern area and continue through the corridor until you reach another switch in the northernmost section.

After activating it, return to the central area of the map, the exit is now accessible.
