Other points of interest[edit]


  1. A chaingun rests on a pillar in the northwest corner of the map. Drop to the pedestal below it and look for a hidden switch in the northwest corner to lower the chaingun. (sector 180)
  2. As you go along the path leading to the blue key, you will pass a gray ledge full of imps. Head for the lift to the south of this ledge and ride it up, then jump out the window and over the ledge to the nukage below. You will find a backpack and a box of ammo here. (sector 381)
