In All Star Karate, players will follow the life of a young, martial arts novice whose noble attempt to save an elderly man from a pack of ninjas brings him face-to-face with a true karate master. The sensei, a cantankerous old-timer, offers his services and teaches his new protege the proper techniques and disciplines of karate and guides him toward achieving the black belt. In single-player, Career mode, players will execute and master various karate moves utilizing the Wii Remote and Nunchuk, or two Wii Remotes, in order to attain the seven different colored belts or achievement levels in karate, including the black belt. Additionally, players can show off their hand, kicking and blocking techniques by sparring with a friend in Challenge mode or by creating their own move sequences to perform with the Kata Editor.
