This game is an electronic game, similar to Battleship made by Radio Shack/Tandy. The game board is set up similar to battleship with an electronic base and a divider to prevent the players from seeing their opponents grid. Each player places 1 ship on their 11x11 grid, with the ship taking up one square. Players have 3 options on a turn, the option of placing sonar markers that indicate the general direction of the opponents ship (N/S/E/W), firing missiles, or moving their ship (a maximum of 5 or 10 units per game, depending on the mode selected). This a fun game that offers more slightly more complexity then Battleship, and more tense battles, since after 1 hit the game is over.
