id Tech 3, popularly known as the Quake III Arena engine, is a game engine developed by id Software for their video game Quake III Arena. It has been adopted by numerous games. During its time, it competed with the Unreal Engine; both engines were widely licensed.
While id Tech 3 is based on id Tech 2 engine, a large amount of the code was rewritten. Successor id Tech 4 was derived from id Tech 3, as was Infinity Ward's IW engine used in Call of Duty 2 onwards.
At QuakeCon 2005, John Carmack announced that the id Tech 3 source code would be released under the GNU General Public License v2.0 or later, and it was released on August 19, 2005. Originally distributed by id via FTP,[1] the code can now be downloaded from id's GitHub account.
