Other points of interest[edit]


  1. After getting the blue key, press the wall west of the southern teleporter in the yellow key room. It opens, revealing three energy cell packs and a switch. (sector 144)
  2. The switch in #1 opens up a door next to the blue key, behind which is a soul sphere. (sector 142)
  3. The switch in #1 also opens a door south of the adjacent teleporter, leading to a BFG9000. The sector itself is too small to receive credit for. (sector 122)
  4. Go down three steps from the rocket launcher, and shoot the eastern wall. It opens, revealing a backpack, 11 imps, and a heavy weapon dude (hard skill only). There is also a switch which lowers platforms containing five boxes of rockets, an invulnerability and a megasphere. (sector 217)


As it is not possible to obtain credit for Secret #3 (see above), the maximum possible secrets percentage on this level is 75%.
