Other points of interest[edit]


  1. In the northeastern blood pit, the switch lowers two blocks, which allow you to reach the pickups on the ledges in the hall to the south. The first of these ledges holds an invulnerability, a health bonus, an armor bonus, and a stimpack. (sector 77)
  2. The second of these ledges holds a rocket launcher, a health bonus, an armor bonus, an energy cell, and an energy cell pack (only on Hey, Not Too Rough or lower). (sector 79)
  3. In the central hub, open the blue door and take either path east. The corners of this hall have face switches, each of which reveal two different secrets. The first holds a medikit, a green armor, and a box of ammo. (sector 132)
  4. The second holds two medikits and a box of shotgun shells. (sector 158)
  5. When you reach the exit door, go up and left, down the steps, then open the door. You will be in the large room you saw at the starting point. The northeast door leads to a lava-filled room where you can get a soul sphere. (sector 261)
