International Karate + (IK+) is a simple side-on beat 'em up. 3 characters appear on the screen - either 1 player and 2 AI, or 2 player and 1 AI - and proceed to kick seven bells out of each other via various karate moves.

Each of the moves scores a different number of points and if you come last in a particular round you are eliminated.

There are some sub-games too, involving your karate-master holding a shield and defending himself against bouncing balls from both directions, and kicking bombs off the screen before they explode.

All in the pursuit of that elusive black belt...

IK+ backflip from movie Grease, here's proof 3 chirinea (34591)

1001 Video Games

International Karate + appears in the book 1001 Video Games You Must Play Before You Die by General Editor Tony Mott.

Atari ST version of IK+

As Archer Maclean was not impressed with Andromeda's Atari ST conversion of International Karate, he decided to do it by himself - although never worked on the ST before (source: The One issue #1, 1988/10).


The 1990 release on the Hit Squad budget label has new cover art, depicting popular action movie stars/martial artists of the time. Recognizable are Steven Seagal, Chuck Norris and Jean-Claude Van Damme.


  • Many sound effects (e.g., the whining when someone's struck down) are sampled from the 1973 martial arts movie Enter the Dragon, featuring Bruce Lee.
  • The backflip animation was based on the fairground scene at the end of the movie Grease, where one of the background dancers performs a backflip. Archer Maclean placed cellophane over the TV, drew the dancer outline frame-by-frame (using a special video-recorder) and then put the result over a computer screen to recreate each image in pixels.


This was the biggest selling reissue on the Hit Squad label ever. Considering that their range included, to name but a few off the top of my head: Rainbow Islands, Bubble Bobble, Power Drift, Batman: The Movie, Head Over Heels (including the initial release of the Amiga/ST port) and New Zealand Story, this says something about the game's popularity.

Trouser Move

Tapping the "T" key makes everyone's trousers fall down. Just goes to show that a black belt is only for display...

This move was so popular that, when the Amiga version was ported to the CD32 console in 1994, one of the controller's buttons was used to activate it. In Ignition's 2003 PlayStation port, it was also included. It can be activated with the Select button. This was also included on the Game Boy Advance version, also by Ignition, and is activated with the Select button as well.
