Other points of interest[edit]


  1. Go to the west side of the northern hallway with lowering lifts. When you do, go back to the east side, down the lift, and to the east again. Take another lift up, open the door, and a soul sphere will be available to the east. There are two secret sectors here, but only one is accessible. (sector 162)
  2. See Secret #1. (sector 542)
  3. Use the switch east of Secret #1, then take the south door back to a hallway you have been before. Head north, then west to a brighter hallway. Open the door to find a green armor. The east door has medikits, and the west door has lockers with plasma guns and energy cells. (sector 187)
  4. At the south end of the water, head east to see a wall with pipes open up in front of you. Flip the switch under it to lower a lift so you can head up there, then open the door to find a teleporter. When you teleport, open the door behind you to find a lift leading down to partial invisibility and boxes of ammo. There are two secrets here, with the sector around the red switch being a secret as well. However, that particular secret is not possible to register without cheating. (sector 321)
  5. See Secret #4. (sector 429)
  6. At the eastern hallways, you may notice that a wall across the water to the west will open. Go there and flip the switch for a lift up. Use the cracked wall in the back to find a teleporter. When you teleport, open the door in front of you, then enter the alcove to the north with a shotgun guy to get this secret. (sector 370)
  7. Once you get the blue and yellow keys, go back to the western bridge and open the yellow door. Flip the blue switch, then go on the bridge and lower it. Lower the western lift where the bridge is as well and you will see a teleporter. This teleporter takes you to a secret room in the northeast part of the map with a rocket launcher and boxes of rockets. (sector 521)
