Other points of interest[edit]


  1. After stepping off the ledge with the rocket launchers, the bridge over the nukage raises up. Look to the northwest and make a running jump to the alcove you see. If you make it, take the path to get an energy cell pack and a light amplification visor. (sector 131)
  2. East of Secret #15 (or from the teleporter mentioned in Secret #12), you can go up a staircase to an ammo depot with a chaingun. The gargoyle switch reveals a secret hall where you can collect health and armor bonuses. (sector 184)
  3. From the top of the wall to the south of the spider mastermind pens, jump between the ledge and the southernmost pen to the ledge below, then go to the ledge that has plasma guns on it for the secret. (sector 398)
  4. At the northwest end of the nukage halls with crushers, you can open one of two walls to find an area with monsters and ammo. The switch at the north end lowers a pillar containing a soul sphere. (sector 487)
  5. In the middle of the map is a mostly empty green field which functions as a teleporter maze. The hint to the maze is provided if you look at the maze from the side, however, when doing the maze, it will be entirely dark. If you manage to go through the teleport maze without teleporting to the start of it, you will access a load of supplies, including the plasma gun, BFG9000, an invulnerability, and numerous types of ammo. Lots of barons of Hell will teleport in as well. (sector 756)
  6. On the left side of the sanctuary is a hall with ridges sticking out in the nukage. In this hall is a large metal wall on the left side. Press on this wall to open it and head outside, where you can collect several kinds of ammo and a BFG9000. (sector 807)
  7. On the blue-floored area in the northwest part of the map, look past the cage for a switch you can shoot, which opens a wall on the other side. Now go to Secret #4 and use the switch to lower the soul sphere pillar, then ride it up, then enter the secret where you can find some weapons and a radiation suit. (sector 1227)
  8. A room overlooking the big nukage pit in the middle of the map holds a cyberdemon (on Hurt Me Plenty or higher) as well as an invulnerability in the lava pit. Picking up this invulnerability reveals a second invulnerability in an alcove nearby, which counts as the secret. (sector 1255)
  9. In the area with the big nukage pit in the middle of the map, hop into the nukage and head along the east side. Just before you reach the corner with the BFG9000, there is an opening you can head to, leading to a secret room with some health and armor bonuses, and you can also collect a invulnerability and a soul sphere as well. (sector 1454)
  10. In the area with the big nukage pit in the middle of the map, hop into the nukage and head along the west side. Right near a trio of energy cells, there is a lion switch that will lower the pillar it is on. After lowering it, go back to Secret #11 to find the teleporter, which takes you to a silo containing, imps, more energy cells, and an invulnerability. (sector 1478)
  11. In the area with the big nukage pit in the middle of the map, head for the southwest corner of the map to find a teleporter which takes you to a platform leading back to the sanctuary. Instead of entering it, turn south and jump down to the building below. If you do it right, you should land on a building where a blur artifact, a chainsaw, a box of shotgun shells, and a radiation suit are nearby. (sector 1504)
  12. South of the teleporter maze and past the red doors is a large lift with a lever switch. Flip it to lower the lift to the area to the south; you will also lower another lift which rises up faster than the one you are currently on. To get this secret, flip the switch once, and then quickly press it again before the lift you are on rises to lower the second lift, then get on the second lift quickly and run through the skinned wall. If you do it right, you will trigger the secret, where you can follow the path of supplies and monsters to a teleporter. This teleporter takes you much closer to Secret #2. (sector 1894)
  13. Press on the wall to the right of the starting point that has multiple rectangles on it to find a lift with shotguns. Ride it up for a berserk pack and a teleporter to the southern end of the map. (sector 1984)
  14. At the north end of the map, just east of the spider mastermind pens, you can find a passage containing two radiation suits and a megaarmor. The teleporter here takes you to the middle of the map. (sector 2001)
  15. By killing all of the cyberdemons on the map, you open up two supply depots next to the map's normal exit. Both of them also lead to the map's secret exit. (sector 2016)
