Kozure Ookami

In 1987, video game manufacturer Nichibutsu released a Japan-only beat 'em up based on the Lone Wolf and Cub series named Kozure Ōkami. Players guide Ogami Itto through an army of assassins while carrying his infant son on his back. A baby cart powerup enables Ookami to mow down enemies with blasts of fire. The game is considered a rarity by the Video Arcade Preservation Society.
