Other points of interest[edit]


  1. At the far southeast corner of the space base, head around the crates on the left side to find energy cells and a medikit. (sector 1658)
  2. At the east end of the map, a lone shotgun guy is near a group of crates. Head behind these crates to find a backpack. (sector 195)
  3. After you get the yellow key, head back to the big area at the southeast and use the key for a lift going up. Head north and turn east, then use the blue terminal. Go west from here past the crates to a lift. Ride it up to get a soul sphere. (sector 586)
  4. Get the blue key, then return to the big area at the southeast. Go up the steps north to the crates and across the curvy path near them, going over the orange line at the start of the curve before the door. You will then need to quickly run, open the door, turn right at the intersection, and dash to the BFG9000 before the door closes. (sector 97)
  5. At the northwestern part of the space base, use the switch to open the ways north and west. Head west, then south around the crates until you reach an energy cell pack. (sector 1714)


Two Hell knights (Things 243 and 244) in one of the caches south of the map have no flags set for any of the three difficulty classes, so they do not actually appear in the level.
