International Karate+
Three fighters, one screen
System 3's fighting game sequel added a third simultaneous fighter, creating chaotic competitive brilliance.
The Spectrum date is 1988, not 1987
⚠ IK+ and its 1985 predecessor International Karate are distinct games and are easily conflated.
IK+ reached the Spectrum in 1988, not 1987 — the 1987 date is the Commodore 64 release. CRASH gave it 91% in February 1988; Sinclair User and Your Sinclair both went 7/10 the following month.
Three fighters, not two
International Karate competed with Way of the Exploding Fist. The sequel, International Karate+ (IK+), leapt ahead by adding a third simultaneous fighter. System 3’s 1987 game created chaos—three combatants on one screen, fighting for points while trying not to finish last.
