Other points of interest[edit]


  1. Open either of the doors to the west, then get to the north end of this area to find a switch. Using this switch reveals an invulnerability (megasphere on Ultra-Violence or higher) between the doors. (sector 80)
  2. At the start, take the first door at the east side and hop in the hole. A lift lowers as you approach it. Get on it, but go back the way you came to find another switch. Press it, then go back to the lift and ride it up. At the top, you can find a BFG9000 and energy cell packs (not on Ultra-Violence or higher) to the left. (sector 167)
  3. Go to the southeast corner of the blue key platform to teleport to an invulnerability. (sector 173)
