Quick tips[edit]

  • This level is a crescent shaped maze (web) of rooms in which switches and triggers are needed to open 'force fields' such that new sections can be accessed. It is easy to lose track of precisely what section you are in.
  • If there is glass in front of a switch, you can destroy the glass (and then press the switch). The two pieces of glass leading to the 'core' area (in between the blue key and yellow key consoles) can also be destroyed.
  • When you find the chaingun pedestal, you must jump across the fence(s) to the rocket launcher pedestal in order to get to the next area(s).
  • In the room (opened up with the yellow key) with a soulsphere and a yellow skull switch that are both slightly too high up to be accessed directly, use the slightly raised floor of one of the entries into the room (there is a gap in the adjacent fence) to sneak your way to the yellow skull switch, which opens a teleporter just to the left that allows you to get the red key you saw behind glass earlier on.
  • The force field in front of the exit teleporter (signaled by the 'NOW ENTERING...' message) is fake, so just walk into the teleport to finish the level.



  1. In the middle of the map under the yellow key, you can find a plasma gun and energy cell packs guarded by a cyberdemon. (sector 466)
