Secrets[edit]

  1. In the area after the start is a round platform containing a soul sphere. This can be obtained by running onto it, or by pressing any of its walls on the north side. (sector 16)
  2. The south-east of the trench near #1 is narrower than the rest – walking over this part will open up a door behind the start, leading to a room with a chaingun. It will also open up the northern part of the trench. (sector 3)
  3. The north-west contains a room with various floors going up and down. There is a room to the east of this with a switch, which opens a room to the east of the southern oscillating floors, containing a blue key, a spectre, an energy cell pack, a medikit, a rocket launcher, and a rocket. (sector 72)
  4. The switch that opens up #3 also opens a room off the middle-right of the fifteen northern oscillating floors, which contains a switch opening up an area north of the easternmost of the three crushing ceilings. This leads to a BFG9000, a partial invisibility, a health bonus, and some ammo. (sector 227)
