MAP09: Bitter Sanctuary is the ninth map of Claustrophobia 1024. It was designed by Steve Muller (Kyka), and uses a MIDI rendition of the music track "Lair of the Blind Ones" from Turok 2, sequenced by Churute.


The level is pretty straightforward: going in any unexplored area opens a monster closet, either behind you or on both of your flanks. Moving into the opened monster closets opens more monster closets (or sometimes just teleport traps), until the entire area is open.

Claustrophobia1024 MAP09 Secret

A lowered secret area and the "striped light" that opens it.

  1. There are two secrets. The first is a stack of twenty health bonuses hidden behind a computer panel in the control room, next to the left window overlooking the lava sea. To lower it and access the secret area, activate the striped blue light in an asymmetric SILVER2 texture in an area left of the control room, with three green terminals. (sector 485)
  1. The second secret is a soulsphere guarded by a zombieman in a small closet on the other side of the control room. Another SILVER2 texture can be activated, raising it and revealing a switch, which opens the closet. (sector 366)
