Download ioquake3

The Quake 3 engine is open source. The Quake III: Arena game itself is not free. You must purchase the game to use the data and play Quake 3 with ioquake3. If you do not want to do that you can play another game made with ioquake3.

There are three methods of installation. The preferred way is to use an official installer. Note that just as before, you can use a Quake 3: Arena CD-ROM from any version of Quake 3 (Windows, Linux, Gold, etc) to get the needed pak0.pk3. You can also copy your pak0.pk3 and CD key from a Steam installation.

After using any of these installers you should upgrade to a test build or check out how to build ioquake3 from source.

We have provided installers for the most popular platforms ioquake3 supports.
