Other points of interest[edit]


  1. When you enter the outside area at the north end of the main area, head southeast to a hall with two revenants. You can use the terminal to the north, which opens a terminal to the east for a second. Enter the passage to get a computer area map. (sector 410)
  2. When you enter the outside area at the north end of the main area, head west, taking the path that does not go down some steps. In this area, use the two lit terminals on the south wall. Afterwards, leave the way you came and take the path that goes down the steps. The rocket launcher to the north is accessible. (sector 447)
  3. At the outside area at the southwest end, a wall to the east is flashing. Shoot it to enter the vent shaft. Follow the health bonuses to a lift and ride it up to find ammo and stimpacks. (sector 1477)
  4. On the same lift mentioned above, hug the east wall as the lift rises to enter a secret vent where you can get a megaarmor. (sector 1507)
  5. In the dark hallway just west of the two big central areas, head north and around to a lift. Instead of using the switch here, open the south wall and take this lift down to a blood-filled area with a medikit, shotgun shells, energy cells, a box of rockets, a box of ammo, and a switch that lowers a soul sphere (megasphere on Hey, Not Too Rough or lower). (sector 1884)
  6. Open the blue door in the central area, then find the switch in this room and use it to lower it and the wall ahead of you. Another switch here will lower the northeast wall leading to the yellow key. Go through the bloodfall to find ammo and a medikit. (sector 2016)
  7. In the easternmost room, you will find two diamond switches on the south wall. You will need to shoot them, and to do so, go to the northeast part of the room and lower the wall there to ride up. Shoot under the switches to activate them, which will allow you to get a BFG9000 in the middle. (sector 2434)
  8. In the large room at the south end of the map, the southwest corner has blood spilling into pools. Go through the bloodfall that is second from the left and follow the passage to a hidden room. The sector with the megasphere here counts as the secret. (sector 2628)
