Other points of interest[edit]


  1. When going along the blue key path, by pressing on the purple door the floor lowers. Underneath this door is a mancubus (on Hurt Me Plenty or higher) or some demons (on lower skill levels). You will notice that inside this compartment one of the Incan faces is purple. Use this to hear a lift lowering nearby. Take it up to a teleporter which takes you to a backpack. (sector 426)
  2. The room just before the exit room has a pentagram switch. Defeat the enemies that appear in this trap and then press four switches to open up the exit. There is a switch in the exit room that lowers a lift back to the main area, use it to return to the hub. Look south to spot boxes of rockets which are now available. (sector 313)
