Freedoom is a project aiming to create a [[Free software|free]] replacement (modified [[BSD License]]) for the set of [[Computer graphics|graphics]], [[music]], [[sound effect]]s, and [[level (video gaming)|levels]] (and miscellaneous other resources) used by ''Doom''.<ref>{{Cite web |url=https://www.nextpit.com/play-doom-on-android |title=Knee deep in the 'droid: weird ways to play DOOM on Android |website=NextPit|date=18 October 2018}}</ref><ref>{{cite news |url=https://www.altchar.com/game-news/brutal-doom-completed-after-8-years-of-development-aQXuP7F3YvNu |title=After 8 years of development, Brutal Doom is finally complete |quote=FreeDoom, the open source initiative to bypass the legalities of Doom's code being open source, while Doom's engine isn't.}}</ref> Since the [[Doom engine|''Doom'' engine]] is [[free software]], it can be distributed along with the new resources, in effect providing a full, free game.

The project distributes three IWAD files: the two single-player campaigns named ''Freedoom: Phase 1'' and ''Freedoom: Phase 2'', and ''FreeDM'', which contains a collection of [[deathmatch (video games)|deathmatch]] levels.<ref>{{Cite web |url=http://www.washburnreview.org/features/freedoom-app-review-play-id-software-s-classic-on-mobile/article_b1672714-1f65-11e9-82cf-f7c66524d22b.html |title='Freedoom' app review: play id Software's classic on mobile |access-date=2019-11-30 |archive-date=2019-11-23 |archive-url=https://web.archive.org/web/20191123004340/http://www.washburnreview.org/features/freedoom-app-review-play-id-software-s-classic-on-mobile/article_b1672714-1f65-11e9-82cf-f7c66524d22b.html |url-status=dead}}</ref> Originally a Boom-oriented mapset, it was later made merely limit-removing, and finally fully vanilla compatible, allowing play through the original executable and conservative ports like [[Chocolate Doom]].<ref>{{cite web|url=https://www.gamingonlinux.com/2024/08/chocolate-doom-310-brings-many-new-features-for-the-classic-source-port/|title=Chocolate Doom 3.1.0 brings many new features for the classic source port|first=Liam|last=Dawe|date=2024-08-06|access-date=2024-08-08|website=GamingOnLinux|quote=The Freedoom single-player IWAD files are now officially supported, since recent versions changed all levels to be vanilla compatible.}}</ref>

A similar project, ''Blasphemer'', aims to create a complete free version of ''[[Heretic (video game)|Heretic]]'', but is less fully developed than Freedoom, from which it has recycled assets.<ref>{{Cite web |url=http://www.jeshimoth.com/jutegyte/blasphemer/ |archive-url=https://web.archive.org/web/20100201110939/http://www.jeshimoth.com/jutegyte/blasphemer/ |archive-date=2010-02-01 |url-status=dead |title=Blasphemer |website=jeshimoth.com |first=Adam |last= Kalmbach |accessdate=2024-08-10}}</ref> Currently three episodes are drafted  and a deathmatch set called BlasphDM is available.<ref>{{cite web|url=https://www.riscository.com/2024/heretic-2024-update/|title=Heretic gets a 2024 update|date=2024-04-25|last=M Hudd|first=Vince|website=Riscository|accessdate=2024-07-14}}</ref> ''Zauberer'' and ''Lastermaul'' have also been initiated for ''[[Hexen (video game)|Hexen]]'',<ref>{{Cite web |url=https://github.com/CireG/Zauberer/ |title=Zauberer project|website=[[GitHub]]}}</ref><ref>{{Cite web |url=https://github.com/GeorgePieVG/Lastermaul |title=Lastermaul project|website=[[GitHub]]}}</ref> and ''Animosity'' for ''[[Strife (1996 video game)|Strife]]''.<ref>{{Cite web|url=https://opengameart.org/content/animosity|title=Animosity|website=[[OpenGameArt.org]]|first=Graham|last=Wilson|date=17 January 2024 |access-date=2024-08-10}}</ref>
