Other points of interest[edit]


  1. Head east of the start and open the door. Find the brown wall to the west and open it to get a radiation suit. (sector 91)
  2. After opening the bars north and west of the start, go north from the start and then up the steps further north. Quickly enter the southeast area to get a backpack and rockets. (sector 92)
  3. At the east side before the long hall with lights, take the steps down and lower the wall with caution stripes to get a blur artifact. (sector 169)
  4. Enter Secret #3 and open the west wall. Quickly run south and enter the nukage and to the southeast door. This lets you go to the east area with a stimpack and a chainsaw. (sector 82)
  5. In the northernmost room, head to the southwest part of the room and open the tech panel to get a light amplification visor. (sector 249)
  6. In the northwest room with the rocket launcher on the teleporter, to get the rocket launcher, open the northeast wall to teleport to it. (sector 265)
  7. In the circular area at the west end of the map, ride the lift with the switch on it up. Shoot the small button directly to the east and the platform directly in front of you will begin to rise to the ceiling. Get on the rising platform -- note that if you miss it or fall off the secret will no longer be accessible -- and when the height is right jump to the outer semicircular ledge with the green armor. If you ride this platform all the way to the top, you will find yourself in a ceiling alcove with a switch which will lower it back to its starting position (though you will not be able to raise it again). It is still possible albeit slightly more difficult to jump to the green armor ledge while the plaform is going down. (sector 63)
