The game had two modes: Super Battleship mode and Classic Battleship mode. Classic Battleship mode is essentially an electronic version of the board game Battleship.

Super Battleship is a naval simulator played by sailing ships to a close enough range to shoot an opponent's ships. Ships have four different weapons: missiles, torpedoes, depth charges, and guns. The game is turn-based with each side giving movement and attack orders within a time limit. A turn ends when either the time limit expires or all ships receive orders. Actual combat occurs within real-time: guns and torpedoes are fired at surface ships while the opponent can fire back. Depth charges are dropped on submerged submarines. Cruise missiles move erratically and must be guided to the target. Crewman can be assigned to repair ships' damaged systems. Ships resupply by capturing bases and storehouses.

The game's interface contains both radar and sonar modes. Radar detects surface ships while sonar detects submarines and mines. Victory conditions vary from escorting freighters to a destination or completely destroying an enemy force.
