Other points of interest[edit]


  1. In the southwest room, open the misaligned part of the west wall to find a chaingun and a box of ammo. (sector 74)
  2. In the northern lava section, get a radiation suit and use the wall to the northwest, which leads to a rocket launcher.(sector 58)
  3. In the northern lava section, climb the east steps and head north. When you see a corpse, open the wall where it is to find a green armor and two stimpacks. Note that the actual sector cannot be registered due to being too thin and with a small floor change. (sector 39)
  4. Take the southwest path in the blood room with the red pillar. At the end, flip the switch on the east side to lower the block with the berserk pack and megaarmor. (sector 55)
  5. In the blood room with the red pillar, open the northeast wall to reach the secret. You can also jump into the lava to the left of the bridge leading to the blue key and head west to reach the wall that has the secret. (sector 121)


Since Secret #3 is impossible to actually trigger, only 80% secrets is possible on this map.
