Other points of interest[edit]


  1. At the large courtyard in the eastern part of the map, flip the switch on the east side, then return to the rocket launcher room. Use the wall to the south here to reveal a lift allowing you to get a super shotgun. (sector 25)
  2. Enter the room northwest of the large courtyard in the eastern part of the map; this is the room with the square lift. Here, use the wall with the darker shade of gray dipped down to reveal a passage with the yellow key. Once you have that, as well as the blue key, open the blue key door and then the yellow key door next. Drop into the channel past the yellow door and follow it to boxes of rockets and a soul sphere. (sector 393)


Three imps, which only appear on Hurt Me Plenty or lower, do not teleport into the map. This is because their teleport destinations (things 228, 229, and 230) are flagged only for Ultra-Violence or higher. Thing 228 is also only flagged for multiplayer.
