MAP09: Chamber of Souls is the ninth map of 1 Monster. It was designed by scwiba, and uses the song "Sinister" from Doom.

Like all maps in the megawad, the map features only one type of monster, in this case the lost soul. It is set in a brown structure cut into rock, which opens up gradually throughout the level, revealing new areas and unleashing new crowds of lost souls.

Letters in italics refer to marked spots on the map. Sector, thing, and linedef numbers in boldface are secrets which count toward the end-of-level tally.


Approach the south wall and press the lion switch that appears. Enter the niche that opens behind you, and press the gargoyle switch. Press it, and another lion switch will be revealed to the south, which opens two niches to the west and east. Enter either one and the wall will lower.

Go down the revealed passage and press the lion switch in the niche to the south. Back in the starting area, two pathways will open to the north. Head through, press the skull switch and enter the door that opens. Approach the metal wall and it will lower. Go along the passage and you will find out that a door opened at its north-eastern end. Enter, and a door will open to the side; another passage will also open in the room with the skull switch. Go in there and press the satyr switch. A rocky ledge will be revealed alongside the main passage, with two skull switches to the west and to the east of the level. Press both switches and grab the keys behind them.

Use the keys to get through a passage to the south of the level. In the dark chamber, approach the twitching corpse. A horde of lost souls will pour into the room. Hold them off until an exit teleporter will reveal itself.


  1. In the north-western corner of the final room is a BFG9000. Picking it up registers as a secret. (sector 173)


In the final battle, a single lost soul may sometimes fail to teleport in.
