Other points of interest[edit]


  1. Head directly south of the starting point to find a crate lowering with ammo on it. (sector 27)
  2. Climb up the blood river after the starting point, then take the steps northwest to the top of the river. At the south wall, run across the white rock back into the lava, east up the blood river again, and quickly to the pit to the south before it closes. You can get a soul sphere to the west. (sector 383)
  3. When you reach the large open area, head to the east side to get a medikit, an energy cell, a box of ammo, and a box of shotgun shells. (sector 959)
  4. Enter the main building and head south. At the corner, press on the east wall to find ammo, a rocket launcher, and a medikit. (sector 1077)
  5. From the entrance of the main building, head north to the edge, then open the door. Go through to hear something lower. Quickly follow the hall and take the first left, going down some steps. You will see a skull switch. Shoot it before it closes, then go back to the hall and head to the bigger room by going east. Past the two columns, you can find an opening on the north wall. Take the lift up to get a plasma gun and energy cell packs. (sector 1737)
  6. Press the switch behind the blue door to remove the green forcefields, then go back to the large open area. Climb back up and find a cave entrance to the south. The green forcefield is gone now, so you can pick up a plasma gun, energy cell packs, and a medikit, as well as enter another cave with an invulnerability and a teleporter leading back to the building. (sector 3643)
  7. On the way to the red key you will be on a high terrace where three cacodemons will come from a room. In this room, look at the left support from the left side to find a switch. Flipping it opens a wall to the east which has a megaarmor, a box of shotgun shells, a box of ammo, a box of rockets, and a rocket launcher. (sector 2415)
  8. In the northeast room of the main building, there is a skull switch to find near the easternmost terminal, at its south end. Shoot it, then go into the nearby hall and enter a smaller one containing energy cells, boxes of rockets, and a megaarmor. (sector 2020)
  9. Open the yellow door west of the building entrance, then go west until the northern wall lowers. Go here, then lower the wall in the northeast corner to get a green armor. (sector 1315)
  10. Continue west from the previous secret into the next room. Use the wall directly opposite of the door to open it. Go back to the door and look north for a shootable button, which will open the fence where you opened the wall. Take the lift down and around to get a box of shotgun shells and a megasphere. (sector 1194)
  11. After using the switch that removes the yellow forcefields (at the northwest end of the complex), use the nearest teleporter and go straight into the cave. In the area that follows, you will have to go across platforms with crushers to the other side. The next area gives you a megasphere and two arch-viles which you must use to jump to the east. Keep going and climb up, then head west to get the secret, which is a room where you can get, among other things, a BFG9000 and a soul sphere. (sector 3089)
