Other points of interest[edit]


  1. At the west hall past the pits, go between the pits at the north side to a lever switch. After flipping it, quickly leave and drop into the nukage pit at the south end, running east up the steps, then southeast through the open passage before it closes. Head north and open the door to get a soul sphere. If you found the secret switch in Secret #2, head south of where the soul sphere was and press on the wall where the red "II" is on the ceiling to find the next secret switch. (sector 547)
  2. In the courtyard south of the starting building, press on all four switches at the base of the rocket launcher pillar, then head back up the steps and press the switch southwest of the pillar. This will lower the pillar, but you will still have to jump to it. While you jump to that pillar, continue your jump to the ridge of the starting building and follow it east. You will soon see a red "I" on the floor which indicates a secret switch required for the secret exit. (sector 275)
  3. At the southeast end of the map, you will find a large room with two shotgun guys behind a terminal to the east. Use that terminal to open the north wall and follow the passage to where the shotgun guys were to find a megaarmor. If you used the two secret switches mentioned in the previous two secrets, use the secret switch where the red "III" is on the ceiling. (sector 172)
  4. Open the door west of the red door and follow the passage up and around until you find a pillar with a beating heart. Past that pillar, head left at the fork and use the gargoyle face. This reveals a switch to the east, and that switch lowers the gargoyle face and reveals a switch there. Press both before they close and the door to the south opens up. This place has a backpack, rockets, energy cells, medikits, and a plasma gun. (sector 667)
  5. After entering Secret #4, go back to the gargoyle face and use it again, then go back inside Secret #4 and the door will be open. Enter to get a BFG9000. (sector 680)
  6. In the room with blood pools at the north end, use the wall at the northeast blood pool to find a medikit and health bonuses. (sector 698)
  7. In that same room, take the passage to the east window that had imps and lower the east wall. Follow the passage to reach a switch which will lower the normal exit pillar beyond the cage, revealing the fourth switch (with a "IV" mark) that opens the secret exit. (sector 748)
  8. In the normal exit room, open the northeast wall to get a computer area map. (sector 761)
