International Karate is a karate fighting game created and published by System 3 for various home computers. Of these versions the 1986 releases for Commodore 64 and Atari 8-bit computers, created by Archer MacLean with music by Rob Hubbard, stand out for their good playability and overall high production values. Although conceptually identical, the ZX Spectrum version, created by a different team and released some months earlier in November 1985, is inferior.
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.
The core game is a two-dimensional, one-on-one, versus fighting game. Players take on the roles of martial artists competing in a kumite tournament. Rather than wearing down an opponent's health, the goal is instead to score single solid hits. After each hit, combat stops and both combatants are returned to their starting positions. Depending on how well players hit their opponent, they score either a half-point or a full point. Matches can be quite brief, as only two full points are required to win, and a point can be quickly scored just seconds after a round begins.
In single player mode, successive opponents increase in difficulty from novice white belts to master black belts. Play continues as long as the player continues to win matches. Between fights, bonus mini-games focusing on rhythm and timing appear, including one in which the player must break a number of stacked boards using only his or her head.
As in newer games in the genre, starting specifically with Street Fighter, the fights take place against a variety of backdrops (8 in total) representing different locations in the world.
The title utilises the standard one-button joystick, allowing players to execute a variety of karate techniques. Unlike modern 2D fighting games, players do not turn around if the opponent is behind them and must instead execute one of three "turn-around" manoeuvres to change direction.

Ports, variants, and re-releases 
A version for the Atari ST home computer was created by Andromeda Software and released in 1986. The port to the PC, published the same year, utilised CGA graphics and therefore was reduced to four colours.
In 2000, a Game Boy Color version, created without input from Archer MacLean, was released as International Karate 2000. It sported some enhancements, and was the basis for International Karate Advanced released in 2001 for the Game Boy Advance.
After the release of World Karate Championship in the US in late April 1986, Epyx was sued by competing video game publisher Data East for infringement of copyright, trademark, and trade dress. The dispute was about similarities to the 1984 arcade game Karate Champ and its home computer adaptations published in 1985. International Karate used the same coloured fighters and had the same points system. The initial trial at the District Court for the Northern District of California began on 28 October 1986. In his decision of 28 January 1987, the court dismissed the allegations of trademark and trade dress infringement but found Epyx guilty of infringing upon Data East USA's copyright on Karate Champ. Data East obtained a permanent injunction against Epyx, Inc., and an impoundment that restrained Epyx from further sale or distribution of World Karate Championship. Epyx was required to recall from both customers and distributors all copies of the infringing work.
The decision was appealed the United States Court of Appeals for the Ninth Circuit, who in November 1988 reversed the decision, stating that while the game was similar, it was not identical, and that one game company can not monopolise one entire sport.
As a result, Melbourne House did not sue System 3 nor Epyx, as the game The Way of the Exploding Fist is also very similar to both of these games, though the game itself also borrowed heavily from Data East's Karate Champ.
