Operation Wolf is an action game released for the NEC PC-FX in Japan. This version is likely a port or adaptation of the arcade classic, featuring side-scrolling shooting action and rescue missions. Players probably control a soldier navigating stages while shooting enemies.  Key features likely include intense combat, varying weaponry, and boss encounters.  While not originally a NEC title, the port suggests NEC's licensing or collaboration with the original developers for a PC-FX release.
