Sauerbraten is fun as well
Bump for good game
all this game needs is better player models and ragdollthe gameplay is great only free game i've seen that you don't have to 'rent'/'buy' guns
You will be 100% addicted. Not the best graphics, but the gameplay is solid and enjoyable. And the game is infinite, so you can keep playing forever (at least until your charge dies) http://www.wolfire.com/black-shades
Although it looks fun, look at the topic name "URBAN TERROR", not "advertise other games here".
