  1. In the central nukage area, get on the northwest lift and head down. Head all the way north and shoot along the north wall to find a room with energy cells, stimpacks (not on Hey, Not Too Rough or lower), a box of shotgun shells (only on Ultra-Violence or higher), and a switch which raises steps nearby leading to the stage to the south. (sector 11)
  2. In the central nukage area, get to the southwest end and press on the skull to the north. Take the nearby lift up and head to the room on the west side. Flip the switch there, then return to the central nukage area and go to the southwest corner to find shotgun shells, a Deathclaw, and an armor 200% upgrade. (sector 247)
  3. When you get to the spiral staircase, make your way all the way to the last door, but when you do, go back and enter several alcoves that have opened to get four secrets containing health bonuses, armor bonuses, and EM-Railgun ammo. (sector 63)
  4. See Secret #3. (sector 65)
  5. See Secret #3. (sector 67)
  6. See Secret #3. (sector 61)
  7. In the red key area, there are IALs through a wall at the west end. Use the westernmost part of the bridge to jump through the wall where they were to get shotgun shells (Hey, Not Too Rough or lower), health bonuses, and a medikit (not on Hurt Me Plenty). (sector 107)
  8. Get the red key, then defeat the IALs through the south wall. Run through it to get EM-Railgun ammo cases (Ultra-Violence or higher), shotgun shells (not on Ultra-Violence or higher), and a stimpack (not on Ultra-Violence or higher). (sector 109)
  9. Lower the north wall in the red key area to get a medikit. (sector 96)
  10. Ride Secret #9 up to get health and armor bonuses (Hey, Not Too Rough or lower), EM-Railgun ammo cases and an energy cell pack (Ultra-Violence or higher), and/or a flame thrower (all skill settings). At the end of the hall you can get an X-Treme Armor, a box of shotgun shells, a stimpack, and an energy cell pack (not on Hey, Not Too Rough or lower). (sector 95)
  11. Lower the west wall at the end of Secret #10 to find energy cells (Hey, Not Too Rough or lower) and depending on your skill level, a soul sphere, an invulnerability, or partial invisibility. (sector 72)
  12. After you get the red key, return to the zigzag bridge and jump to the east wall. Head to the small corridor (look out for the crusher) and into the room to the west to get either a darksphere or an X-treme Armor depending on your skill level. (sector 155)
  13. Head south from Secret #12 to find EM-Railgun ammo cases. (sector 119)
  14. After you get the red key, head to the southernmost hallway and enter the teleporter to enter the room behind the cage with medikits, ammo, and a soul sphere (only on Hey, Not Too Rough or lower). (sector 295)
  15. Use the switch at the west side of Secret #14, then the one on the east side. Leave the room to the east, then open two doors going west to get to the lowered platform in the southwest corner with a flame thrower and energy cells. (sector 296)


The following multiplayer-only Things have no flags set for any of the three difficulty classes, so they do not actually appear in the level: seven riot shotguns (things 784 through 790) and a shotgun shell case (791). The same goes for six deathmatch starts (777 through 780, 782 and 783) but because of special handling in the engine, they function normally in the level.
