MAP28: Obliteration is the twenty-eighth map of Claustrophobia 1024 2. It was designed by Cody Stirm (Butts) and Joonas Äijälä (Jodwin), and uses a MIDI rendition of "Slayer of Light" by Ensiferum as its music track.


Map of Obliteration
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.


You begin in a courtyard that is overlooked by imps and mancubi; on Ultra-Violence and Nightmare skill levels, the mancubi on the south platforms are replaced with arch-viles. Activate the lift in front of you (you will automatically collect a megasphere, weapons and backpacks under your feet) to get a plasma gun, then ride the lift up and look east to see a pair of face switches on a low wall. Shoot either switch to lower the wall, then pull the chain switch behind it - this will open the north-west column in the courtyard below, but will also allow a pack of imps and shotgun guys to teleport to the walls, and a cyberdemon to teleport to the north-west platform. Use the supercharge and energy cell packs that appear on the lift to help you kill them.

Pull the switch inside the north-west column and kill the demons that teleport to the courtyard, along with an arch-vile that appears at the top of the lift, then ride the lift up and walk south-west to pull another chain switch that has been revealed - a pack of cacodemons will begin flying in from the rocks outside the playable area, and a megasphere and ammo will appear on the lift to help you kill them. Drop back into the courtyard and pull the chain switch that has opened inside the north-east column to lower the bars at the top of the lift, then ride the lift up and pull the chain switch behind those bars.

Pulling the switch will lower the south-east column in the courtyard and eventually reveal another switch - it will also open the towers at the south end of the courtyard to reveal revenants, and more revenants will teleport to the courtyard along with imps, demons, cacodemons and Hell knights (as well as a spiderdemon on Hurt Me Plenty or higher). Once the final switch is revealed, pull it to lower the exit teleporter in the middle of the courtyard.

Other points of interest[edit]


There are no official secrets on this map.


An arachnotron (Thing 212) in the northern-west monster cache has no flags set for any of the three difficulty classes, so it does not actually appear in the level. It was probably meant to appear on skills 1-2, as the same cache has a spiderdemon at skills 3-5.
