Other points of interest[edit]


  1. When you flip the switch that lowers the barriers blocking the blue key, return to the east side of the map. Go to the southeast corner of the large brown room and drop down to get a megasphere. (sector 102)
  2. Once you shoot the eye switch above the starting point, the room nearby will be open. Cross the bridge and climb the steps, then enter the side room where the cacodemons came from. Use the metal wall next to the barrels to reveal a lift. Ride it up and drop down. The secret area here has stimpacks, armor bonuses, a backpack, ammo clips, and shotgun shells. (sector 134)
