Other points of interest[edit]


  1. In the building at the south end, get to the northwest end and use the switch in the southwest corner to lower the blocks, then get to the northeast end and use the switch there. This lowers several walls, including the big one to the west. Go there and head north, then east to a soul sphere. (sector 1310)
  2. In the building at the south end, get to the northeast end and use the switch to lower the surrounding lift. Head east into the dark to find a berserk pack and energy cells. (sector 1131)
  3. Take the aforementioned lift in Secret #2 up and take the teleporter to the north. Take the lift up and head west until you get to the middle stone wall. Lower the middle of it to find a blur artifact. (sector 1535)
  4. At the northernmost end of the main corridor, look up to the windows and kill the twelve Commander Keens. This will open a door at the left end of the north wall. Go through it and head to the northwest corner to find a blur artifact. (sector 330)
  5. Head east from Secret #4 to find a long hall with an arch-vile and a teleporter to the final battlefield. (sector 1613)
