Other points of interest[edit]


  1. Head to the southeast portion of the southeast maze area, then take the lift up. Past the horde of zombiemen, take the northwest lift all the way down to spot some steps. As the lift rises, jump to these steps, then approach the silver structure. Through the window, you will reveal a BFG9000 while the structure lowers. (sector 47)
  2. In the pool with the soul sphere and the health bonuses which reveals a spider mastermind, you can head through the eastern opening to collect a super shotgun and shotgun shells. (sector 110)
  3. At the northeast end of the map, head for the gray lift and lower it. As it rises, time a jump to the northwest, and you should land on a megaarmor and an energy cell pack. Alternatively, ride the gray lift and jump through the red window, then jump off to the north to reach the secret in a much easier manner. (sector 119)
  4. Entering the round room on the west side of the map causes the segments to rise and lower. Stay on the segment you are closest to as it falls, then enter the alcove to the northeast to collect a computer area map. (sector 222)
  5. West of the room with multiple textured pillars is a room with imps up on two walls. Lower both of these walls, then press on the northern wall with a red stripe on it. You will get a medikit and two armor bonuses here. Open the wall to the right to get a soul sphere. (sector 233)
  6. In the room with the multiple textured pillars, approaching them causes them to rise and lower. Get onto the red pillar and ride it up to the opening where you can get a rocket launcher, medikits, and a box of shotgun shells. (sector 249)
