Other points of interest[edit]


  1. At the start, head into the water going east and head to the platform with blue lights. Use those to reveal a chaingun. (sector 269)
  2. At the start, head into the water on the left and head north to a dead end. Look at the east wall and find a nub to use, which lowers a barrier. Continue until you reach a platform with a box of ammo. (sector 253)
  3. After you get the red key, enter the closet that opens in front of you and use the monitor with static. After you turn it off, enter the room just to the west and lower the southeast corner of the room. Ride it up and enter the nearby vent to get shotgun shells and a berserk pack. (sector 90)
  4. After you get the red key, return to the large room with multiple color lights and enter the west closet. Open the vent here at the south end to find a backpack. (sector 2057)
  5. In the outside area at the east end, head west at the T-intersection and lower the block using the monitor with static to get a medikit. (sector 192)
  6. In the outside area at the east end, head to the southeast, then west to a single health bonus. There is a small recess in the north wall. Use it, then head south from Secret #5 and enter the small room here to get a megaarmor and a health bonus. (sector 2097)
  7. Once you get the yellow key, leave the outside area and head back into the room before it. Enter the corridor at the west side and use the south wall to find rockets and a rocket launcher. (sector 176)
  8. In the southwest room, use the double monitor with static at the northeast end, which will open the southwest corner of the room. Use the terminal there, and after some time the northwest corner will open, allowing you to get a soul sphere. (sector 2046)
  9. Descend the steps going to the west end of the lab until you find a broken vent at the east side. Using the thin wall at the east side, enter the vent and follow it all the way to a plasma gun and energy cells. (sector 1807)
  10. At the northwest room of the lab, use the broken monitor on the west wall to find a berserk pack and energy cells. (sector 1788)
  11. In the blue key room, use the south wall to find a broken vent with a box of rockets and an energy cell pack. (sector 1797)
  12. Use the left terminal in the blue key room, then leave and head to the north wall where you can swim underneath the wall and into a secret room further north, containing a backpack and energy cells. (sector 1231)
  13. In Secret #12, go to the terminal and use the wall to the east to find a different terminal. Use that one to enable remote boot, which causes a Doom game to play on the other terminal and monitor. After a while, the monitor opens and reveals a megasphere. (sector 1242)
  14. After you get the blue key, retrace your steps until you get to the largest room at the west side of the map, where there will be a compartment open at the east side. Enter this compartment and open the south wall to find rockets. (sector 1773)
  15. In Secret #14, use the monitor at the south wall to get a backpack and armor bonuses. (sector 2148)
  16. After using the switch behind the blue key door, head north through the thin corridor as the doors open. After the fourth door, use the monitor with static at the west side to arrive in a secret maze section where you will deal with arch-viles. (sector 1836)
  17. In the final arena, when the eastern building opens, head through either door and press on the northernmost (linedef 10217) or southernmost (linedef 10215) walls. This will lower the middle section which contains backpacks and an invulnerability. (thing 2248 via script 24 and thing 2532, ZDoom's "secret trigger" actor)
