Yie Ar Kung-Fu (イー・アル・カンフー Ī Aru Kanfū) was a 1985 arcade fighting game developed and published by Konami. It was considered by many gamers in Japan to be the basis for modern fighting games. The games pit the player against a variety of opponents, each with a unique appearance and fighting style. The player could perform up to sixteen different moves, using a combination of buttons and joystick movements while standing, crouching or jumping.
A sequel, Yie Ar Kung-Fu II, was released a year later. The sequel was released only for home computers and was never ported to the arcades.
