id Software has announced from their annual QuakeCon event that they have open-sourced their Wolfenstein: Enemy Territory and Return To Castle Wolfenstein games under the GNU GPL. id Software is known for open-sourcing their games and engines after some years of use and this day has finally come for these two very popular Wolfenstein titles.

Those interested in obtaining the source-code to Enemy Territory and Return To Castle Wolfenstein can find the source in this FTP directory. The new source releases are the ET-GPL.zip, RTCW-MP-GPL.zip, and RTCW-SP-GPL.zip files.
