The Way of the Exploding Fist
The move executed each time is defined based on the character's direction, the joystick/keyboard positioning, and on whether the fire button is depressed, in a system which became standard on single-button control systems.
To win each bout you must score 2 Yin-Yangs - a perfectly executed kick/punch scores a full one, whereas a less forceful contact offers half a point - the best moves also offer more points. In the one-player game, you advance through a Dan by winning two successive bouts, and a single win for the opponent means game over. The champion in a two-player duel is decided by points after 4 rounds.
