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...
