DIRTY BOMB - Steam F2P

[Star Pilgrim]

Great game I must say.
Highly addictive.

Here is their site, or you can simply search on Steam and join the madness.

This game is great fun.
I highly recommend investing the zero dollars required to play it.

It's like a prettier version of TF2, but with some really cool mechanics and every game mode is objective based.
