You sunk my battleship! Prepare to sink battleships and much more in this portable World War II Naval simulator. Take command of a complete naval fleet, including submarines, destroyers, aircraft carriers, and, of course, battleships. Customize your own flagship and determine how you want to play the game. Take down the axis powers using a combination of turn-based and real-time strategy mechanics - strategically position your fleet, then engage in real-time 3D combat. Each weapon has its own unique effects, from the giant 18-inch main batteries of your battleship to torpedoes launched by the stealthy submarines. Wireless multiplayer pits friend against friend in a battle for the high seas!
