Warsow is a free first-person shooter based on Quake II. The game features very fast-paced action, with speed and movement "tricks" a central part of the game. There are a variety of weapons and power-ups. The game also comes with bots, so you can practice solo or add a few extra players for a small LAN party. The visuals in Warsow are quite nice, and the characters in the game have a very cool "cartoony" look.
Unfortunately I haven't been able to play it with anyone else yet since the game does not seem to get along with my current router (a D-Link DIR-601). :-\ Oh well, but I'm sure it will be fun at a LAN party!
