ZDoom is a discontinued advanced source port that was popular for many years because of its rich feature-set. It had Boom compatibility; complete support for Heretic, Hexen, Strife, and Chex Quest; as well as many additional new features, including slopes, uncapped framerate, and z-clipping. It was originally based on a merger of the ATB Doom and NTDOOM source ports.
The large number of editing features supported by ZDoom made it the port of choice for several independent game projects, notably Foreverhood, Action Doom 2: Urban Brawl, Chex Quest 3, and Harmony. ZDoom also served as a popular code base to build upon, with numerous other source ports derived from it or using portions of its code.
ZDoom was created by Marisa Heit (Randi) soon after the Doom engine source code was released in 1997, and by 1999 many foundational features had been added.[1] Others also made significant contributions over the years, including Christoph Oelckers (Graf Zahl) and Braden Obrzut (Blzut3).
Although Heit officially ceased the project in January 2017,[2] the ZDoom legacy continues to thrive in several forks, notably GZDoom, UZDoom, and Zandronum.
