    ezQuake
    ALL FILES FOUND HERE ARE _OLD_, PLEASE MOVE TO https://ezquake.github.io FOR THE LATEST VERSIONS Combining the features of all modern QuakeWorld® clients, ezQuake makes QuakeWorld® easier to start and play. The immortal first person shooter Quake® in the brand new skin with superb graphics and extremely fast gameplay. The project started in August 2004 as a derivate of the FuhQuake client by fuh which is a derivate of ZQuake QuakeWorld client by Tonik, one of the current ezQuake developers. Finally, ZQuake is a derivate of QuakeWorld client made by Id Software. This company has created the Quake game itself and later on released the source codes of game executables under GNU General Public License. Because id Software didn't release the whole game for free to the public you still need some of the original files from Quake to play QuakeWorld using our client.
