Other points of interest[edit]


  1. The doors to the room inside the circular room at the center of the map cannot be opened directly. Walk south from those doors and look at the wall on the west side. Notice that one of the panels is green instead of brown. Push this panel and all the doors in the central room open up. Inside is a partial invisibility, stimpacks, armor bonuses, and ammo. Up to three monsters can be found in this room as well. (sector 55)
  2. In the blue-floored area west of the starting point, press the switch to lower the lift at the southern end of the area. Once you ride up, go to the end of this hall and open the wall to find a chainsaw. (sector 110)
  3. After flipping the switch in the southwestern part of the map, the hall behind you opens up revealing a large nukage room. Look towards the column at the northwest part of this room. Run to the backside of this column to find a berserk pack. (sector 119)
  4. From the circular room at the center of the map, walk west to the blue-floored area but turn right immediately into the passage. At the end of this passage, right next to the stimpack in the corner, you will find a hidden button to push. Do so, and then go to the western side of the blue-floored area to an open hallway. You can find a rocket launcher, a radiation suit, and health and armor bonuses among other things in this hallway, plus there is a shortcut back to the nukage room where Secrets #3 and #5 are. (sector 143)
  5. At the southwestern corner of the large nukage room mentioned in Secret #3, open the brown wall and the wall after that to reach a sector with a stimpack and a box of ammo. (sector 169)
  6. Take the hall east of your starting point and open the door. In the next room, walk around the beam at the northwest part of this room. There is a tall techno pillar here, but if you look closely, there is also a switch. By pressing this switch, a bridge raises above the nukage to the door to the east, leading to a hidden area above the place behind the red door. (sector 203)
  7. From the circular room at the center of the map, head east and take the left path at the fork. Follow this hall until you see the light, and follow the light that trails left to the wall. Lower this wall (for reference, this wall also has a bullet hole on it) to find a secret room with rockets and a teleporter. The teleporter takes you to a room with two stimpacks and a megaarmor. (sector 204)
  8. Take the hall east of your starting point and open the door. In the next room, go into the nukage and run south and around to the lift. If you look at the wall to the left, you should see a green ridge at the bottom. Open this wall to find a backpack along with health and armor bonuses. (sector 372)
  9. Open the blue door and go to the room at the bottom. There are four alcoves close to the switch in this room. Enter the third one you come to and open the wall here to get a soul sphere. (sector 431)
  10. Take the hall east of your starting point and open the door. In the next room, go into the nukage and run north into the dark passage. A plasma gun will be here along with an energy cell, a stimpack, and a teleporter back. (sector 528)
