Good, free, fun and multiplayer games

[FROGGEman2]

Don't get the wrong idea. I'm not talking Guild Wars here. I'm talking Toribash or Gang Garrison. So, what are some fun, multiplayer, small and preferably indie games you can suggest? Something you could enjoy with a friend over voice chat?

What are your reccomendations?

Battlefield Heroes is fun, if you like 3TH Person cell shading shooter

Combat Arms is a good game, its almost like cod4, but free.
