You'll need lightning fast reactions to knock out the Knife Thrower, stop the Stick Fighter, and trip up the evil Tom Tom Brothers in this action-packed martial arts contest! Are you sure you're tough enough? Because it'll take all your strength and skill to master the moves in KUNG FU, beat your opponents, and rescue the fair Sylvia who's held captive on the top floor! The action is non-stop, and just when you think you've got your enemies licked there's always a Giant, a Snake, or a fire-breathing Dragon to contend with in KUNG FU!
The player controls Thomas with a four-way joystick and two attack buttons to punch and kick. Unlike more conventional side-scrolling games, the joystick is used not only to crouch, but also to jump. Punches and kicks can be performed from a standing, crouching or jumping position. Punches award more points than kicks and do more damage, but their range is shorter.
Underlings encountered by the player include Grippers, who can grab Thomas and drain his energy until shaken off; Knife Throwers, who can throw at two different heights and must be hit twice; and Tom Toms, short fighters who can either grab Thomas or somersault to strike his head when he is crouching. On even-numbered floors, the player must also deal with falling balls and pots, snakes, poisonous moths, fire-breathing dragons, and exploding confetti balls.
An extra life is given at 50,000 points; thereafter, the rest of the game is on "survival of the fittest" mode.
