MAP25: The Process is the twenty-fifth map of Claustrophobia 1024 2. It was designed by Justin Murphy (KingKill33) and Steve Muller (Kyka), and uses a MIDI rendition of "Cruisin' for a Bruisin'" from Beavis and Butt-head for the SNES, sequenced by JILost, as its music track.

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.


Take the shotgun and kill the chaingunner and imps waiting outside, then open the door ahead to enter a room with more of the same monsters. Take the super shotgun then go to the switch on the south wall (a compartment with a megaarmor will open next to it), kill the chaingunner that teleports behind you then flip the switch to open the north door. Kill any imps and demons waiting behind that door, then continue north to another door - more monsters will teleport in behind you - and open it to dispose of a shotgun guy. Continue west to a computer terminal and press the red button on it, which will cause various monsters (including a revenant and pain elemental on Ultra-Violence (UV) and Nightmare (NM) skill levels) to appear outside, then leave the room through the north doorway before walking west and south to a suspended crate that has the yellow keycard on it.

Go back to the room in the south-east corner of the map and open the yellow key door here, then climb up the crates to your right to get the blue keycard - as you do so, note the Hell knight and other monsters that appear on the rocks visible through the east window. Now return to the area north-east of the computer terminal to find a small red button with a blue marker underneath it, then press this button to open a large door to the west. Kill any imps waiting behind the door then go down the steps to a berserk pack, fight off some lost souls along with more imps that appear around you then head south to another door and open it to reach a ruined building. Press the "LOCKED" panel on the east wall to lower the door next to it, run east to reach a supercharge on a crate then go to the east end of the pit to find another panel - before pressing it, you should dispose of the knights, mancubus and imps that appear behind you. Press the panel to trigger an ambush by shotgun guys, imps, knights and revenants, then climb back up to the ruined building and step on the teleporter that has opened; this will send you to the exit switch, which is on a platform next to the starting point.

Other points of interest[edit]

On UV and NM, a rocket launcher is placed just south of the computer terminal. On Hurt Me Plenty or lower, it is replaced with a box of bullets.


  1. Once you reach the pit near the end of the level, do not drop into it right away. Carefully walk south onto a very narrow ledge that goes along the entire perimeter of the pit, and traverse it all the way to a megaarmor. (sector 1823) An easier method of reaching this secret is to jump to the crate with the supercharge, then run south to the nearby crate. From here, you can step onto the aforementioned ledge to reach the secret.
