Other points of interest[edit]


  1. If you look east from the blue key pedestal, you might see a red button on a high wall. It is possible to use this button from the ground floor below. Use it while there and you will open a secret room near the entrance to the area. This room has a megaarmor and a backpack. (sector 31)
  2. In the same room as above, take the south door and head south a bit to hear a lift lower. This lift is to the northeast, which leads to a small passage that has a switch at the end, which will reveal another switch further on. Note that the lift itself is a secret and can be hard to register, to do so, just stand on it as it rises. (sector 68)
  3. The last switch in Secret #2 will open up a teleporter if you go back west from the large room. This teleporter will be at the south end and will drop you off at the soul sphere in the middle of the hub. (sector 4)
  4. On the way to the red key, head along the bridges until you reach the T-junction, where you should head left (north). Flip the switch on the brown wall and the next switch to open the door at the opposite end of the junction, then use the wall to the south of the first switch to find a secret passage leading to a chainsaw. (sector 120)
  5. Flip the switch where the chainsaw is to open a window, where you can see a switch in the distance. This switch is only accessible while inside Secret #4, so shoot at the switch from the window to open a nearby alcove. This alcove contains a rocket launcher and rockets. (sector 129)
  6. When you enter the room with the block with four switches, press on a wall just to your left while entering (southwest) to find a road full of health bonuses. (sector 186)
  7. At the end of the previous secret, press on the western wall to find boxes of rockets and a megaarmor. (sector 187)
  8. Press on the wall just to the right while facing the exit door (south) to find a computer area map. (sector 183)
