Other points of interest[edit]


  1. Enter the north entrance and fall to the left when you do. Head south to get a soul sphere. (sector 458)
  2. After lowering the red key, go to the northwest side, then look southeast and shoot the switch. Doing so opens a door at the northwest part of this area, leading to a medikit, health bonuses, and a BFG9000. (sector 1005)
  3. Just before the entrance to the north, go on the left wall all the way north to a switch. Afterwards, head to the right wall and head north to find a radiation suit, a chaingunner, and a plasma gun. (sector 1173)
