Other points of interest[edit]


  1. Head west of the starting point and use the terminal opposite of the blue door to get a backpack. (sector 963)
  2. Take the lift near Secret #1 down, then head all the way north and use the switch. Use the left wall on the lift and when it rises, go through and get armor bonuses, a medikit, and a computer area map. (sector 920)
  3. The same switch that lowers the super shotgun lift where Secret #2 is will also lower a different lift to the southeast. After triggering the switch, head south and east to get a megaarmor. (sector 266)
  4. At the eastern hall of the main building, head south towards a lift that lowers until you hear a second lift lower. When that happens, backtrack north and into the side room to the east, then into the room to the south before it closes to get energy cells, a plasma gun, and medikits. (sector 314)
  5. Go to where the rocket launcher is and find a switch on the southeast support beam. Flip it, then quickly head south and go on the square that had a rocket. From here, go west and into the wall near the lamp to get two boxes of rockets (one on Ultra-Violence or higher) and a soul sphere. (sector 888)
  6. After going across the round platforms at the north end, go west along the ridge above the lava, which will lower the wall ahead. Keep going and another wall will lower with a radiation suit and a switch. Flipping it will lower a wall at the southwest end of the lava pit, revealing a passage to a megaarmor. (sector 747)
  7. At the northernmost end of the map, a monster closet opens up as you go up the curved staircase. Enter this closet and use the terminal to trigger a lift to the north, leading to armor bonuses and a berserk pack. (sector 414)
  8. At the top of the curved staircase, make a jump to the northwest closet, which will open a wall to the northwest with a medikit and an energy cell pack. (sector 322)
  9. Open the blue door near the start and open up the closets in the hall. The closet that had a sole spectre has a floor lamp. If you use it, it will lower, along with two lifts at the closets at the west end of the hall. Take either of them up (both closets are the same secret sector) to get medikits, armor bonuses, a box of shotgun shells, and an invulnerability. (sector 357)
  10. After you get the yellow key, go to the yellow door east of the starting point. Head down the steps and enter the silo. Take the lift up to an energy cell pack, then press on the left wall to get a soul sphere. (sector 895)
  11. In the south closet in Secret #9, open the wall where a candle is and use the switch, then head west and south, into the outside area with red and green pillars. Follow the armor bonuses to get the secret path. (sector 230)
  12. Keep heading past Secret #11 to see a large warehouse with lots of monsters. After clearing them out, head to the northeast side and press on the green crate to lower it. Behind it are health bonuses and a megaarmor. (sector 554)
  13. Head southeast from the warehouse and into the lava pit to the west. Cross the stepping stones to get a megasphere. (sector 841)
  14. When you teleport from Secret #13, enter the building to the north. Open the door in here and head through the corridors until you find a lift. Take it up and open the door to get a soul sphere. (sector 232)
  15. Head back to the large outside area and go all the way to the east side. Head around the blue torches east of the building and go north to a brick wall. Use it and take a lift up. At the top, go to the other side of the fence to find a switch that lowers a berserk pack and a megaarmor. (sector 537)
