Warfork Gameplay (livestream - skip ahead 1m20s)

The title says it all. Warfork is the revival of Warsow. Warsow is cool (and super hard to master) but does not have servers running
Warfork is an ironically-named fork of Warsow, has CC0 art assets and is for now only released on Steam. The source supposedly is mostly based on qfusion, the source code is supposed to be available as a DLC.
