See a fist? It shows where you're going to be hit. Block your opponent's hits with "G" button for upper block, "A" for lower. Don't forget to hit your opponent with UP and DOWN buttons for upper and lower jabs (or "W" and "E", if you like). And, yeah, he's going to defend himself too.
Choose your candidate to fist fight for the White House. Guitar Hero-like gameplay makes it easy to enjoy a dogfight. P.S. No future presidents harmed during development of this game.
