Other points of interest[edit]


  1. Once you have the red key, return to the hangar at the starting point and open the large door at the northernmost gray shack (this is marked for the blue key, but only if you use the sides with the blue markers on them, if you use any other side of the door it is treated like a red door). Inside this shack is some ammo, a megasphere, and a computer area map. (sector 67)
  2. At the northern end of the conveyor west of the starting point are some crates blocking the way. Climb these crates up to the vent and go east. The teleporter takes you to a BFG9000. (sector 276)
  3. At the northern end of the conveyor west of the starting point, open the door and then open the southern door to find a megaarmor. (sector 547)
  4. At the main road intersection, go west and open the door that leads to the courtyard with the fountain. Go through the open door on the right and then the open door to the north to find former humans and demons guarding a plasma gun, a backpack, and energy cell packs. (sector 2023)
