Other points of interest[edit]


  1. Get on the step north of the start and face southeast. Shoot the switch and return to the starting point to get rockets and cell clips. (sector 28)
  2. A switch in Secret #1 reveals a teleporter to the northwest. Take it to find a secret area with the two crushers having boxes of rockets underneath them. (sector 190)
  3. When going on the west edge of the south area, head south to the blood and enter the northwest teleporter to get a box of rockets, a box of shotgun shells, and a soul sphere. (sector 184)
  4. After accessing the switch at the north end, return to the teleporter to Secret #2 and flip the switch north of it. This reveals steps going northeast, which you should take to see a megaarmor to the north. (sector 105)
