V2 is coming may 2006, for a beta test. So its going to be free for a while

V2 Will include..

Bomb maps
Helicopters & Jets (Yes, you can spray and pray loads of missles at the ground )
Boats
Even bigger maps (Trust me, these maps are HUGE)
Anti tank missle launcers
More selection of tanks
Item store (Buy weapons from the money you've earnt from killing other players) These weapons include PGS1, M41A, Claymores etc

This game is so more addicting than CS or CS:S. I was playing free when it was V1, and i loved it when you got your whole team into a humvee driving around the streets shooting at people in buildings
