a fantabulously awesome (yet underplayed) freeware online multiplayer game. Being a low budget deal and being freeware they don't advertise so the massive hordes of n00bs haven't overrun it yet. as far as gameplay goes, its an FPS, and the two teams you can choose to play as are humans (they play like a standard FPS) and aliens (which use mostly melee attacks, and are either small and quick but easy to kill, or ridiculously huge)
