Walkthrough[edit]

Map of Slaughter Until Death
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.

Essentials[edit]

You start in a crossroads with four switches, all of which are guarded by hightech guys. Each switch will open a closet with shotgun guys and demons; after opening all four closets, you can flip a switch inside each one to reveal one more switch which opens the central room. Fight through another group of demons and bazooka men to reach the hole in the center of the map, then enter it to teleport to an enclosure with four teleporters. You can enter the teleporters to visit the other corners of the map and kill the remaining monsters or press the switch in the enclosure to end the level.

Secrets[edit]

  1. Go to the north switch in the north-east region of the map, then open the back wall of the left-hand alcove to find four clips, three stimpacks and two shotgun shells. (sector 102)
  2. Go to the north switch in the south-west region of the map, then open the back wall of the left-hand alcove to find four stimpacks, four shotgun shells and an armor. (sector 105)

Bugs[edit]

There is a complex interaction between two demons (thing 299 and 298) and moving sectors in the southwest area (or player 2's area in co-op) that may cause a softlock due to the covers to the skull button (linedef 697) not sliding down. This can be easily avoided in singleplayer if the player kills or agitates these two demons before entering the southwest area. Explanation:

  • Demon thing 299 is placed overlapping demon 298, and with a corner of its hitbox overlapping a ceiling. Intuitively this means demon 299 is stuck in both a ceiling and the other demon, though the demons are fast enough to run out of this position so under normal circumstances they are not stuck deep enough to matter.
  • Ideal scenario: If all buttons are pressed in this southwest area while 298 is overlapping 299 (i.e. 298 is not agitated and moving around), the covers to the skull button open up fine, allowing the skull button to be pressed so walls open up like normal and the player can teleport to the exit. This happens in singleplayer if the player is careful not to disturb the demons while going to the teleporter from the player 1 start area (northeast), and then visits this southwest area afterwards.
  • Softlock scenario: If a player agitates demon 298 before entering the southwest area (i.e. 299 exclusively overlaps the ceiling) and pushes all the buttons, the covers to the skull button will fail to operate, softlocking the player inside this area.
  • The ideal scenario is enabled by peculiar handling by the engine of thing 299 stuck in both a ceiling and another thing; because it is stuck in a thing, it is not also considered stuck in a ceiling. If it was stuck in a ceiling, the covers to the skull button would be broken, which would make this area inescapable, which is what happens in the softlock scenario.
