688 Attack Sub , released in 1991 for the Sega Genesis, is an action & adventure game that drops you into the depths of Cold War-era espionage. As a commander of either an American or Soviet attack submarine, you'll embark on ten challenging missions set against the backdrop of international tensions.
Gameplay involves navigating through treacherous underwater terrain while managing your crew and resources to complete objectives. You'll use various stations, including sonar, weapons, navigation, helm, radio, and periscope, but many tasks can be delegated to your crew members. With a focus on realism, the game's close-up control panels are balanced by occasional digitized images of surface ships and crew.
