Hard Battle has three modes of play: the standard one-player tournament mode, a two-player competitive mode, and a two-player five-character team challenge mode. There are ten characters in the game (twelve if Ranma and Pantyhose Taro's cursed forms are counted). All twelve characters are available for the two-player modes. After completing tournament mode Pantyhose becomes a playable tournament character. Happosai is unlockable by entering a code.
