From the back of box:
Grav-Ball is a sporting event of the future requiring skill and courage. Played in a zero-G court, the two six-man teams try to score with a five-kilogram steel playing ball. Anything can happen in the meantime! Legal actions include body, hand, and foot checks, passes, and actual goal shots. Illegal actions, or actions requiring a penalty check, include striking with the ball or elbow, shooting the player with the ball, and all-out assaults. The usual result of such body contact is a high player turnover rate. The player's body armor does not guarantee physical safety from opposing players or from the ball itself. If the game gets too rough or a fight occurs, Heartless Huey is released. This invulnerable robot will incapacitate the nearest player. He then moves on to the next, nearest player until all are terminated or the fighting stops. All of these factors make Grav-Ball an exciting and action-packed game of the future.
