Doomsday of UAC (commonly known by its filename UAC_DEAD) is a single-level PWAD designed by Leo Martin Lim. As part of their 10 Years of Doom feature, Doomworld named it one of the ten best WADs of 1994.
One of the first ever fan-made Doom mods, UAC_DEAD features an attempt at creating realistic-looking vehicles and environments. It contains a replacement sky graphic, and uses careful flat and texture choices in places to simulate colored lighting. It also includes the first known instance of the self-referencing sectors trick, used to create both invisible stairs and an invisible chamber enclosing a cyberdemon.
UAC_DEAD was originally released June 23, 1994. It also appeared on Maximum Doom as UAC_DEAD.WAD, as UAC_DEA2.WAD, and as E1M4 of DEATHM2.WAD.

Technical information[]
This map occupied the E1M8 slot in order to use the special tag 666 twice, exploiting a peculiarity of Doom's handling when more than one boss monster is present in the map. This peculiarity was changed in The Ultimate Doom, and as the Doom source release inherited the change, the map is unplayable in many modern source ports (because the red key cannot be obtained). Chocolate Doom and PrBoom have option settings which allow the trick to operate as intended, and ZDoom and GZDoom identify the level through its checksum and automatically apply the correct compatibility flag.
Inspiration and development[]
The sky texture in Doomsday of UAC is taken from "Nightfall" (NIGHTFAL.WAD), a single-level PWAD designed by Josh "Phallus" Fallon and released on June 14, 1994.
Trivia[]
The invisible stairs are meant to be reminiscent of the film Indiana Jones and the Last Crusade.
