Other points of interest[edit]


  1. Follow the main path to a room with a metal stage where it splits up. Go right, and straight, and climb up the natural stone stairs. Run through the window and through the door to your left, then keep right where an opening in the wall reveals a teleporter that brings you to a megaarmor, and a plasma gun. (sector 386)
  2. Back in the metal-stage room, take the left exit now, and search the left wall for a slightly brighter segment. Press, enter, get backpack. (sector 398)
  3. Make your way over the lava lake in the east (opened by a switch next to the cyberdemon's home cage) until you reach the coffin-shaped platform in the center. Look at the path of elevated islets and jump into the hot sauce. Go round the rightmost islet which is actually a peninsula, to find the hidden megaarmor. (sector 662)
