Other points of interest[edit]


  1. In the main area, head behind the light on the east side to find a blur artifact. (sector 226)
  2. When you teleport the first time, you will be in a brick room. Open the southeast corner to get a berserk pack. (sector 159)
  3. When you teleport the second time, you will see an invulnerability across the bridge. The bridge will close when you get to it, but you can simply go around the bars to collect the invulnerability. (sector 194)


A revenant (Thing 570) in the exposed brain of the final boss has no flags set for any of the three difficulty classes, so it does not actually appear in the level.
