How to Play Muhammad Ali Heavyweight Boxing
Quick start
Create or choose a heavyweight, then work through the rankings toward a title bout. Keep a safe distance with jabs, mix body and head punches, and retreat when stamina is low. Read the opponent’s guard before throwing power shots, because missed swings leave a long opening for counters.
Controls
D-pad: move around the ring, guard, and aim punches high or low. Face buttons throw left and right punches and use the stronger or context punch according to stance; combinations produce hooks and uppercuts. Start pauses. Check the control display before the first bout because training and fight screens use different context actions.
