From the rules:While doing research, Dr. Banner became the victim of radiation gone wild. Now, in times of stress, he becomes transformed into the rampaging Incredible Hulk. He must build a lab to 'cure' his terrible problem. Each player tries to build one for him. But watch out - the players must sometimes rev up and unlease The Hulk who could, in his rage, 'smash up' the Labs that are being built! Players must rebuild and survive the Hulk's attacks to win. POW! - BoardGameGeek
