Overview

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.

Fast facts

  • Developer: System 3 (Archer Maclean).
  • Release: 1987.
  • Innovation: three simultaneous fighters.
  • Scoring: points for hits; lowest scorer eliminated each round.
  • Bonus stages: balls bouncing across screen, comedic interludes.

The three-fighter dynamic

Adding a third combatant transformed gameplay:

  • Alliances: two fighters could gang up on one.
  • Backstabbing: alliances never lasted.
  • Chaos: tracking multiple threats simultaneously.
  • Elimination: lowest scorer removed after each round.

The dynamics emerged naturally from the mechanic.

The bonus stages

Between fighting rounds, comedic interludes:

  • Ball bouncing: deflect balls using head, feet.
  • Shield: block bouncing objects.
  • Absurdist humour: contrast with serious fighting.
  • Trousers: enemies could lose their pants.

The bonus stages became as remembered as the fighting.

Technical achievement

Archer Maclean’s programming impressed:

  • Three large sprites with fluid animation.
  • No slowdown during combat.
  • Responsive controls despite complexity.
  • Smooth scrolling backgrounds.

The Rob Hubbard soundtrack

The C64 version featured memorable music:

  • Loading screen composition.
  • In-game atmosphere.
  • Bonus stage themes.
  • Demonstrated SID capabilities.

Competition with Fist

The fighting game rivalry continued:

  • Different approaches to similar concepts.
  • IK+ innovated with three players.
  • Fist pioneered the genre.
  • Both games respected; players had preferences.

Legacy

IK+ proved adding complexity could enhance rather than dilute gameplay. The three-fighter mechanic created emergent dynamics no two-player game could match. The bonus stages showed games could have humour without sacrificing quality. System 3’s reputation for technical excellence continued.
