Brian Jack's Uchi Mata is a Judo fighting game for the Commodore 64 computer. It is notable for its control scheme that allowed users to perform various fighting techniques. A similar control scheme would be used a year later in Capcom's arcade game Street Fighter. Another feature that would later appear in Street Fighter was the inclusion of hidden moves: moves that were not included in the instruction manual that players would have to find on their own.
