1984 · Fighting · Arcade

Overview

Karate Champ (1984) is Data East's one-on-one karate tournament game, an early template for fighting games, with moves set by two joysticks.

Deep Dive

Karate Champ stages point-based karate bouts judged by a referee, awarding full or half points for clean strikes, with bonus rounds of breaking bricks and dodging objects between matches. Instead of buttons, the player combines the directions of two joysticks to produce different kicks, punches and blocks — an early form of the move inputs that later fighting games adopted. It set out much of the one-on-one format that games such as Street Fighter built on.

Developer Story

Karate Champ was developed by Data East in 1984. It was one of the first one-on-one fighting games and established the format — two players in a dojo, fighting in rounds, with a judge awarding points. The dual-joystick control system mapped different combinations to different attacks. Karate Champ directly influenced Street Fighter (1987) and every one-on-one fighting game that followed.
