"Kaiser Knuckle follows the same fighting game conventions established by Street Fighter II. The player's character fights against his or her opponent in best two-out-of-three matches in a single player tournament mode with the computer or against another human player. The player has a character roster of nine fighters to choose from, and three bosses, each with their own unique fighting style and special techniques." -Source: wikipedia
