George Foreman's KO Boxing lets you climb into the ring as the former Heavyweight Champion to challenge nine boxers in three different circuits -- defeat all nine opponents and you'll win the International Championship Belt. The viewpoint is set behind the boxer, with two damage meters at the top of the screen. As you and your opponent trade blows, the meters will shrink in size until one of you suffers a knockdown.
Standard moves include left and right crosses, jabs, blocks, and "superpunches," which are earned by performing combinations. Use these special punches at the right times and your opponent will receive serious damage. Should you lose a fight (through a KO, a TKO, or by decision), you'll have one shot at a rematch before the game is over. Players can resume progress via passwords given after each fight.
