Hi
For anyone who does not know Fistful of Frags(FoF for short) its a cowboy themed FPS that runs on the source engine (same engine as TF2,HL and Portal). There are 4 different teams and to my knowledge its mostly death match (though there might be different game modes coming). Its free on steam and I suggest to give it try.
Tip: spam x-4 when your playing.
