A bunch of Neanderthals nerds have raided your village and have kidnapped all the babes! As the Caveman Ninja duo, Joe & Mac must face all kinds of prehistoric perils in order to rescue all the girls. Features awesome graphics & fun filled gameplay.
This game is known in Japan as "Tatakae Genshijin - Joe & Mac". A bootleg of this game is known as "Stone Age". The Caveman Ninja title seems to be a parody of Data East's earlier arcade hit Bad Dudes, whose Japanese name was "Dragonninja". (arcade-history)
