Other points of interest[edit]


  1. Travelling west from the yellow key (which can be found by going north from the exit), you will reach a yellow door. Just before this is a secret lift to the left (a dark grey wall flanked by light grey columns). Lower this, and take it up. The switch on the left opens up a teleporter (located south-east of the yellow key), and the switch on the right lowers the lift. Continue ahead to reach an area with a rocket launcher, two boxes of rockets (multiplayer only) and two stimpacks. The teleporter takes you to a podium from which you can jump to an area with a radiation suit, a medikit, a box of shells, and a computer map. Both areas with items count as secrets. (sector 19)
  2. See #1. (sector 21)
  3. Go through the aforementioned yellow door, and take the lift in the south-west corner. Jump onto the ledge and continue round to the west. At the centre of this passage is a secret door (flanked by light grey supports) leading to a room with a switch, which counts as a secret. The switch opens up a path over the columns in the nearby nukage, leading to a platform with a megaarmor and four health potions. (sector 82)
  4. In the north-west of the level is a nukage area with a blue-door locked room containing a plasma gun. In the south-east corner of this area is a secret door (flanked by light grey supports) leading to a room with a green armor and 0-2 imps, and a link to another room with a partial invisibility and an imp (two on hard skill). (sector 119)
  5. The blue key is located in the north of the level. In this room is a switch which opens a lift and a path to an outside area. (sector 156)
  6. Take the lift east of the start and go through the teleporter maze to the north-west corner. Two doors open up – take the west one to a room with a window to a room with a supercharge on a platform. This can be accessed by pressing the south-west wall, which is a secret door leading to a passage to the supercharge room. The supercharge will lower on entering (the other end of this passage is also part of the same secret sector). (sector 52)
