Disrepair is a 10-level PK3 for Doom II that requires GZDoom source port to play. It was the first mapset created by speedrunner Andrea Rovenski (Cyberdemon531), and features such additions as DECORATE monsters, 3D floors and scripted events. Released in March 2014 as the first part of her SecretDoom series, Disrepair features short, fast-paced maps, as well as "Survival Mode" (serving as Episode 2 of the wad), which changes seven of the maps into an endless horde mode with some slight objectives.
The sequel, Disrepair 2 was released in 2016, and expanded on several locations featured in Disrepair, in addition to various new locales.
Disrepair begins on April 13th, 2123, three months after the first Hell Gate rose in the Congo Sector. Your mission is to travel through the training barracks of the Industrial Sector and clear out the demonic presence in the area. The job should be easy, right?
