The game is a turn-based game, I GO U GO system with alternating phases. The game contains: a turn-based sequence of play, with the US having the slight advantage to play second as they broke the enemy code, allowing for interesting counter-moves, all main battleships, carriers, and heavy cruisers as individual units, and minor ships, marines or air units regrouped in groups and flotillas, a simple (but not simplistic) set of game. You can play hot seat, against the AI, or in multiplayer mode.
