International Karate +, often abbreviated as IK+, is a karate fighting video game published in 1987 by System 3, originally for the Commodore 64, Amstrad CPC and ZX Spectrum. It has since been ported to a number of other platforms. The Commodore 64 version was released in the U.S. under the title Chop N' Drop. In the game, three karateka fight against each other on a beach, trying to be the first to score six points. After every two rounds, there is a bonus game which is either deflecting bouncing balls or kicking away bombs.
