In Japan, Shogun Assassin was actually turned into a video game where you controlled Ogami Itto and had to fight your way through wave after wave of assassins. Ogami Itto came complete with son Daigorō – although you had to carry him on your back for most of the game, with the pram only coming into effect once in a while during the levels.
The game was actually named “Kozure Ookami” when it was released.
The game was released in 1987 by Nichibutsu in Japan only.
The game is considered a rarity by the Video Arcade Preservation Society as there are no known instances of the game being owned, although it is available in ROM form for MAME.
