Map of Dilapidation
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.


At the start, press the switch in front to open the door. Go through the next door and open the door to the left in the next room. Enter this room and press the switch to the left to lower the red key pillar. Grab the key then exit the room and go up the stairs in front to find the red door. In the corridor open the door to your left. Shoot at the barrels to destroy them and get the blue key. Go back to the corridor and open the blue door. Destroy more barrels and press the switch to lower the yellow key. Pick it up then open the yellow door back in the corridor. Here is the exit door, but it's locked and blocked by bars. There's switches in the two nukage pools, one to lower the bars and the other one unlocks the exit door. Once you complete the switch sequence, enter the exit room and go to the left to find the exit switch.

Other points of interest[edit]


  1. In the gray STAR hallway (north of your starting position) is a flashing arrow on the floor and ceiling pointing at a monitor on the east end. Press this monitor, and the computer paneling in the south of the hall will act like an elevator. Take the elevator up to find a plasma gun. (sector 90) The elevator may also be activated using the monitor directly in front of you when you first enter the room from the southwest; whether this was intentional or not is unknown.
  2. In the penultimate room, activating the west switch causes closets to open in the northeastern part of the room. In the northernmost closet, part of the northern wall is misaligned. Press it to find armor. (sector 321)


When playing in a non-ZDoom-based source port, the wide lights in the gray STAR hallway (linedef 671) suffers from egregiously poor texture alignment, and the exit door (linedef 1995) has a garbled texture. These are nodebuilding errors caused by the then-current version of ZDBSP, which occasionally did not write a level's SEGS data correctly.
