|Planned as a pack-in cassette title for Amiga's never released Power Module peripheral and described as 'the first machine-interactive video game', offering head-to-head play, with one player the submarine commander and the other the destroyer captain. Each player would have had their own screen display and set of commands. The Power Module was dropped in favor of the Power Play Arcade carts, and the game’s development only went as far as this version. Catalog description: 'You know he's down there. But where? Your sonar is picking up indiscriminate blips. Then a pattern emerges. You've found him. You launch a round of depth charges over the side, and the explosions rock the ship. You smile confidently and check the scanner: completely blank. Suddenly, there's a blip. And another. Or... You know he's up there. But where...'
