Other points of interest[edit]


  1. North-east of the large nukage pit south of the exit is a Poison sign which is a secret door leading to a radiation shielding suit. (sector 236)
  2. After going through the blue door, head west and down the stairs at the far end. The pillar in the centre of the cross will lower, allowing access to two switches at the top. The western one lowers the pillar back down, the eastern one opens up four rooms in the nukage areas containing various items and enemies. The north-eastern one (containing a medikit and a multiplayer-only energy cell) counts as a secret. (sector 139)
  3. The four platforms in the corners of the large nukage area behind the blue door count as secrets and are impossible to miss. (sector 17)
  4. See #3. (sector 32)
  5. See #3. (sector 33)
  6. See #3. (sector 34)
  7. The area west of #5 (the south-west platform) with the switch counts as a secret and is impossible to miss. (sector 136)
  8. The area south of #4 (the south-east platform) which is opened up by the switch in #7 counts as a secret and is impossible to miss. (sector 147)
  9. The room with the switch which opens up the exit area counts as a secret and is impossible to miss. (sector 231)
  10. After the nukage south of the exit has lowered, a secret area to the west will be available - it contains four lost souls, a spectre, a radiation shielding suit, and a soul sphere. On multiplayer there is also an energy cell. (sector 198)
