Other points of interest[edit]



  1. When you open the leftmost door, press on the vent straight ahead to get an invulnerability. (thing 27 via thing 26, ZDoom's "secret trigger" actor)
  2. In the exit room, there is an eye in the northeast corner. Using it makes it glow and reveals a passage to the left. You can find the BFG9000 and energy cell packs here. (sector 2043)


If you examine the eye inside Secret #2, a message will display, which ends up being random. You will get messages which actually are tips to other maps in the wad, specifically Vader's other levels, such as:

  • "There is a hidden invulnerability sphere at the west end of this map"
  • "Shoot the Archy face above the bloody altar in Blackrock!"
  • "Jump down the hole in the control room above the reactor in Thunderpeak powerplant"
  • "Don't miss the hidden BFG in the room right before you face the Terminator...(break) There is a tiny switch in one of the corners!"
  • "In Blackrock you can activate some switches in a secret (break) Look for those south of there, near the elevator to the blue skull!"
  • "In Blackrock, don't open the door next to the one that requires the red skull (break) It's a trap..."
  • "Jump down near the elevator in Termination for a secret plasmagun"
  • "Don't waste your time in the map KDiZD Launch Site (break) Torm set the time limit quite low :("
  • "Don't try to make the Terminator damage itself with it's grenades (break) It won't have an effect, although it's bleeding!"
  • "Better avoid the big blood pool in Blackrock until you have some weapons (break) There are a lot of Cacos in there!"
  • "Dude, you get annoying... leave me alone!" (this message pops up if you ask for advice ten times)
