Other points of interest[edit]


  1. Go down the steps at the start and use the wall with the pipes to use a lift leading to a super shotgun and a box of shotgun shells. (sector 36)
  2. In the room with four doors, take the south one that does not require the red key and go to the southeast corner and use the wall. You can climb the steps to reach a box of ammo, a chaingun, and a backpack. (sector 65)
  3. In the large room with lava gushing into the pool below, you can go through the gushing lava to find a soul sphere and a radiation suit. (sector 71)
  4. In the maze area to get the red key, there are several yellow lights on the walls. One of the lights on the west side of the room is blue. Use it, then go back to the large room with the lava gushing down. The right wall will be open. Follow the path behind it to get to a soul sphere. (sector 353)
