International Karate is a karate fighting game created and published by System 3 for various home computers.
Epyx licensed and published the game in the US as World Karate Championship in April 1986. Except for a new loading screen and necessary tuning for the American NTSC television system, the US releases were unchanged.
International Karate + a successor which expanded the gameplay through the introduction of an additional - although not player controllable - karateka, was released in 1987. Through the unauthorized release of International Karate + Gold in 2001, this player was made controllable using a joystick adapter.
