Secrets[edit]

  1. From the blue key (which is located in the north-east in the area with various paths inside columns over a blood floor), jump south, east, south, east, north then turn and jump east then north to a platform containing a supercharge and an imp (two imps on hard skill). (sector 114)
  2. Just south-east of the exit is a long east-west room with a megaarmor at its east end. The eastern wall here is a secret door leading to a room with a chainsaw and (in multiplayer only) four rockets. (sector 46)
  3. The very north-west area of the map (with the nukage pit containing a supercharge and other health and armor items) contains a secret door on its south wall leading to a room with a teleporter to a room with a supercharge (which can be lowered using a switch). Both of these rooms count as secrets. The trigger line for the door to the former is the step leading to two health bonuses in the west of the north-west area – however, this step is too high to cross, so only 50% secrets and only 88% items are obtainable. (sector 89)
  4. See #3. (sector 85)

Bugs[edit]

  • The map has red doors but no red key. The map can still be completed, however.
  • The map has a yellow key but no yellow door. Linedef 642 is surrounded by trim colored for a yellow door, but it a regular door, and will open without any key.
  • Some secrets cannot be reached (see above).
