Walkthrough[edit]

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]

You start outside the north-east door in the hub, which you used in your previous visit. Go round to the north-west door, which will open as you approach to reveal a demon and zombiemen, then go through and head west until you enter an alcove with armor bonuses. The back wall will open to reveal a cacodemon (or one or two barons of Hell on Hurt Me Plenty (HMP) skill level or higher), but you should not go forward until these enemies are dead, as you will open a monster closet behind you containing demons. Enter that closet and flip the switch on the dividing column to raise some steps to the exit door, then open the door to find a button.

Pressing the button will not end the level; instead, you will drop into an ambush by zombies and imps, plus spectres on HMP or higher. Press the button at the west end to lower the walls on either side and reveal more imps, then enter this compartment to find the real exit button.

Other points of interest[edit]

Run through the nukage in the hub to find a shotgun and a megaarmor.

Secrets[edit]

  1. After passing through the north-west door in the hub you will come to a couple of steps. Press the walls on either side of the middle step to lower lifts that go up to four stimpacks. (sector 130)
  2. Go to the top of the stairs leading to the fake exit. A wall will lower at the bottom, revealing imps guarding a stimpack, a box of shotgun shells, a box of bullets and the chaingun. (sector 216) The button here opens the door leading back to the hub.
  3. After pressing the fake exit button, open the brown wall in the south-eastern corner to find a computer area map. (sector 204)
  4. In the same room, open the north-eastern wall that is indicated by a floor arrow to find a box of bullets, armor bonuses and a medikit. (sector 195) The door at the top of the steps leads back to the area before the fake exit.
  5. In secret #4, open the northern wall at the bottom of the steps to find a supercharge. (sector 209)
