Legal status

From Quake Wiki

Quake Trademark[edit]

Quake is a registered trademark of id Software. All other trademarks are properties of their respective owners. Shambler, Fiend and other characters may also be property of id software.

Engine[edit]

The source code of the Quake engine has been released under the free and open-source GPL license. You can find it on GitHub or the id Software FTP server. Lots of forks have been created, you can find some at Engines

Game code[edit]

Early versions of the QuakeC source files have been released under the GPL: ftp://ftp.idsoftware.com/idstuff/source/q1tools_gpl.tgz

Unfortunately the 1.06 source does not have a GPL notice attached by oversight. Changes have been backported from the QuakeWorld source to the 1.01 GPL source, you can find the resulting code at https://www.gitorious.org/quakec-v1-01-clean/quakec-v1-01-clean/commit/c313e4e881ecc21ac28e9d5ce1872c621788659c

Media[edit]

Original models, maps, textures etc are property of id Software and not available under a free license. There exist a few full replacement projects with GPL license.

The Quake palette, though, has been permitted by John Carmack to be freely distributed (citation needed).

Compiler tools[edit]

A set of compilers tools has been released as GPL.
