George Foreman's KO Boxing — About this game
George Foreman’s KO Boxing puts timing and defense alongside punching. Choose a speed and one- or two-player play, then use jabs, uppercuts and body blows to find an opening. Holding both buttons builds a superpunch, but the opponent still needs watching while you prepare it. Victories earn improvements to punching power, recovery or movement speed. Three knockdowns in one round produce a technical knockout, so a weakened opponent can make a focused attack worthwhile.
