Your ultimate goal is defeating the evil Colonel Chi who threatens your island, and the game leads you from California all the way to the South China Sea.In the game, you can move left or right through several scrolling screens that constitute one level. One button is used to fight the randomly spawning ninjas in beat 'em up fashion, while another one can be used to enter buildings. The player has an inventory that can hold only one item at a time. These items are used to solve some small puzzles within each stage.
