Other points of interest[edit]


  1. In the starting area, head to the middle room and get the shotgun, then lower the wall to the south for a switch. This will open the south door at the west side, which leads to a green armor. Make sure to use the east switch in that area for another secret later on. (sector 21)
  2. At the west side of the starting area, approaching the north door opens it and the side rooms to the left and right. Quickly enter the left room, go around the wood column, and use the south side to lower it, then quickly run back to the hall and into the north room, getting either of the shotgun shells on the crates to the left or right before they rise. Both count as one secret. (sector 138)
  3. In the room east of the starting area with seven doors, open either of the northeast doors and head into the darkest part at the northeast. At the southwest corner, use the wall to find rooms with a stimpack, a box of shotgun shells, a medikit, and a soul sphere. (sector 264)
  4. In the soul sphere room in Secret #3, if you used the switch at the east side of the green armor room mentioned in Secret #1, there will be a room to the east with a megaarmor. (sector 277)
  5. In the room east of the starting area with seven doors, open the south door at the southeast, then open the wall to the east to find a medikit. (sector 279)
