Everything you need is at: http://kevan.org/rumble.cgi?rulesFrom the website:Rumble is a fast-paced game of superhero combat, with players bidding energy points on attack and defense, attempting to outguess their opponents and knock them out of the game.Heroes can be imbued with stock super-powers selected from the online archive, or with powers invented by the players at the start of each game - Rumble is as much about the clash and interaction of varied super-powers as it is about thoughtful bidding and bluffing.It's a game for any number of people, and works equally well face-to-face (tracking energy with pencils or beads or coins, scrawling powers onto cards and handing them out) as through the Internet (via any real-time conversation thing). - BoardGameGeek
