Description from the back cover:
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!
Kung Fu for NES was released in October 1985 in North America.
The arcade version of the game is known as "Kung-Fu Master".
