We have not yet had an official release. Nonetheless, you can still get icculus.org/quake3 packaged for a few Operating Systems or build it yourself from Subversion.
The Quake 3 engine is open source, this does not mean that Quake 3 Arena the game is free. You must purchase the game to use the data!
We have provided installers for the most popular platforms icculus.org/quake3 supports. These have been tested, and if they do not work you can report bugs to us about them.
There is a Windows installer by Philip Nelson.
Installers for Linux are provided by Lugwig Nussel, a developer of this project at. The installers are based upon loki-setup.
Coming soon.
If you're lucky your Operating System provider or someone else using it may have already done all of the work for you. Please report problems with these to those who are guilty.
Firstly, we have packages for the i386 and amd64 versions of Ubuntu and Debian Linux, thanks to Bruno "Fuddl" Kleinert.
To install these, as root run dpkg -i package.deb.
There are also i686 binaries built on Ubuntu made by Pascal de Bruijn. Untar this into /opt/ or where ever you keep weird isolated installs. There is a decent chance these will work on most distributions, these are not .debs.
Ed "Sketch" Byrne has been so kind as to provide i386 RPMs for Fedora Core 3, Fedora Core 4, and RedHat Enterprise Linux 4. Be sure to read his Readme to learn how to install it.
Gentoo users can just emerge quake3 to get a recent snapshot of our Subversion repository.
This part assumes Windows users are using Cygwin. If you aren't, TortoiseSVN is a good client.
We all can compile it ourselves:
After you've done all of that, you can double click on the .app file, or change to the /Applications/Quake3/ directory in a terminal and run the binary.
Building on Windows is slightly complicated. You can either use Microsoft Visual C++ or MinGW. MinGW works better currently; both methods are described in the README that you already are supposed to have read.
The id software patches are still needed before installing this project because they contain updated .pk3 files. We mirror them for your convenience:
