Eons ago, a man underwent a strange phenomenon. His fist exploded. Many of his tribe called programmers saw this wondrous sight and decided to try it themselves. They were not very good at it. They ended up in pain with cries of "Yie-ar-kung-fu" or "Ninja- Master". So the exploding fist reigned supreme.
Then rival tribe celled System 3 decided to cash in on the trend, launched it's own version of Fist, "International Karate", and rather inevitably it also failed miserably.
Now years later International Karate is back. What a shame - it's still no good.
On the plus side, like Fist, it has 16 moves including a variety of kicks and punches, and some goodish backdrops. Nice looking game, but a mite too easy to complete for my liking.
