Released by Taito, Operation Wolf (World, set 1) is one of the many iterations of Operation Wolf found in arcades. The existence of multiple sets suggests potential minor revisions or variations in the game's code or ROMs over the course of its release and distribution. The core gameplay, however, would likely remain consistent with its predecessors: action-packed rail shooting with distinct stages and enemies.
