Other points of interest[edit]


  1. In the hall to the north of the red door, go towards the east door and use the terminal to the south of it. Now open the east door and go north to get a chaingun. (sector 285)
  2. Open the red key door, then use the lift to go up. Continue south, then head east to the area with a few crates. There is a slimefall at the northeast end. Use the window, then go through and use the switch inside. Get out and head back west, where there should be an open door in the middle that leads to the armor bonuses, medikit, energy cell pack, and plasma gun inside. (sector 753)
  3. In the hall outside of the crossways where cacodemons teleport in, use the east wall (where you teleported from to reach this area) to find a blur artifact. (sector 1185)
