Two to eight drivers find themselves in an arena, each aiming to wreck his opponents' vehicles.
Each turn, players program one action token and one movement card, which are then revealed and resolved in turn order. (Unless you played your "1st Player" one-shot action token to get out of a hellish situation -- or take advantage of a once-in-a-lifetime impending ram-o-thon...)
The game features no weapons, so you MUST ding up your own car in order to inflict damage to the opponents' cars. In fact, managing that self-inflicted damage is at the heart of the game. (And there's only so much a factory-installed ramplate can take.)
Once a third of the cars have been wrecked -- either because the armor is completely gone from one section or the car sustained one too many critical hits -- whoever has scored the most points (i.e. inflicted the most damage to opponents) AND is still alive is declared the winner!
