id Tech 3, popularly known as the Quake III Arena engine, is a game engine developed by id Software for its Quake III Arena. It has been adopted by numerous games. It competed with the Unreal Engine; both engines were widely licensed.
id Tech 3 is based on id Tech 2, with a large amount of the code rewritten. Successor id Tech 4 was derived from id Tech 3, as was Infinity Ward's IW engine used in Call of Duty 2 onward.
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. It was originally distributed via FTP, and moved to GitHub.
