Has anyone played this game? It's for the computer and looks pretty bad arse. Users can create vehicles and can tow stuff, crawlin, mudbogging, rescuing stuck vehicles, Dakar style racing, trail running, test trucks on tank traps or just drive. I would recommend just checking out the site. A few guys from another forum play this game and really like it.
It is even free to download!
