About ZDoom

ZDoom is a family of enhanced port of the Doom engine to modern operating systems. It runs on Windows, Linux, and OS X, and adds new features not found in the games as originally published by id Software.

ZDoom ports may be used and distributed free of charge. No profit may be made from the sale of it.

ZDoom was originally created by Randi Heit using id Software's and various others' sources. Its successor ports GZDoom and QZDoom are now maintained by Christoph Oelckers, Braden Obrzut, Rachael Alexanderson, and Magnus Norddahl.

Why would I want to use ZDoom instead of regular Doom?

Consider all these features that ZDoom has that are not found in the standard Doom originally released by id:

With thanks to...

id Software / John Carmack
These are the people who developed Doom and later released the source code for the Linux port. Without them, there would be no ZDoom. Some of the functions from their Quake2 game DLL source were also used.
Marisa "Randi" Heit
For creating ZDoom and maintaining it for nineteen years.
Bernd Kreimeier
Packaged up id's Linux code for the initial source release.
Raven Software
Portions of Heretic and Hexen were used in ZDoom.
Christoph Oelckers
Most of the DECORATE support as well as numerous bug fixes. Also, for the OpenGL renderer, as well as advancing ZScript along to the point where it is today.
Chi Hoang / Team TNT
Responsible in one way or another for Boom, which provided a significant codebase for ZDoom. Information about Boom can be found on the Doom Wiki at DoomWiki.org.
Lee Killough
For all his brilliant work on both Boom and later MBF. Portions of MBF were used in ZDoom, primarily to fix Boom bugs.
Martin Collberg
Creator of the Cajun Bot.
Sebastien Bacquet
Created qmus2mid which was used to determine the structure of DOOM's MUS lumps so that the game would have music.
Greg Lewis
Released his DeHackEd source, without which adding DeHackEd support would have been much harder.
James Haley
Creator of the Eternity Engine source port, helped design the specifications for the Universal Doom Map Format and allowed the use of some parts of his advanced polyobject code to be used in ZDoom.
Simon Howard
Creator of the SMMU source port, allowed code from it to be used in ZDoom.
Rachael Alexanderson
Creator of the QZDoom source port which merged in Norddahl's True-color software renderer in with GZDoom.
Magnus Norddahl
Creator of QZDoom's true-color software renderer, as well as adding in post-processing and flexible window scaling support to both ZDoom and GZDoom.
