Take the postapocalyptic vehicle combat of the Mad Max movies, and add them to an online role-playing game. The results will look very much like Auto Assault, an upcoming online RPG that will let you push the pedal to the metal as you race around a shattered landscape while blowing up everything (and everyone) you encounter. When you're not busy blasting things, you can hang out in towns and interact with your fellow players, upgrade and repair your vehicles, and get new missions so you and your group can go out there and start gunning again.
