Other points of interest[edit]


  1. As you go along the path on the west side of the map, it dips down into the damaging blood. When it does, press on the inner wall and enter the teleporter. You will be inside the central cage from before where you can get a BFG9000. (sector 5)
  2. Head north from the area with the cages until you see a plasma gun and rocket launcher to the east. Take them and enter the dark passage behind them. Press on the northeast wall and go along the corridor until you reach the backside of a prison cage where you can get a computer area map. (sector 194)
