Other points of interest[edit]


  1. At the hall west of the starting point, use either of the walls to the west that are misaligned to open the way to shotgun shells, a medikit, and a megaarmor. (sector 35)
  2. When you open the doors leading from the starting area to the main area of the map, take the door north of the starting point and use the lift. As it rises, look to the southeast and jump to the higher ledge, then go through the wall to find health bonuses. (sector 49)
  3. Take the steps southeast of the starting point, then run straight west. A door will open as you get to the southwest side. Quickly head up the southwest steps back to the starting point and into the open door to the west to get a box of rockets and an energy cell pack. (sector 110)
  4. In the main area, there are two square pyramids. Go towards the south one, then through the brown slimefall to the southeast to find radiation suits. (sector 131)
  5. At the northeast end of the map, going towards the switch will cause lifts to lower. Head back to the previous room and go on either the northwest or southeast corners of the room with a box of rockets and an energy cell. Both corners count as one secret. (sector 240)
  6. In the main area, there are two square pyramids. Go towards the north one, and fall into the moat at its base and head for the northwest corner. There is a teleporter here that takes you to a green armor. (sector 244)
  7. In the room at the east side with the two rising and lowering metal lifts, get on the east lift, then as it rises, jump through the vines to the southeast to get a box of rockets. (sector 264)
  8. In the main area, there are two square pyramids. Go towards the south one, then northwest to the wall with red vines and through one of them into a corridor. Hang a left when it branches, then left again at the red lights. Go through the stained glass to get armor bonuses. (sector 351)
