International Karate is all about a karate tournament in which you can participate. It gives people the chance to participate in some good old hand-to-hand fighting on the Wii as a downloadable game for VC.
You can play against the computer or a friend. A round consists of three bouts, lasting thirty seconds each. When taking on a friend, winning a round presents bonuses such as a special bonus stage and extra points. Fighting the computer means you need to win every round in order to proceed.
