Doomsday of UAC
Doomsday of UAC (uac_dead.wad) is a classic and well-known WAD file for Doom 1. It does not play properly under Ultimate Doom and most ports due to a change in the behavior of sector tag 666 between versions. Chocolate Doom allows uac_dead.wad to be played by emulating the older version.
