The game puts you in control of an entire fleet in the navy as you try to defend different coastal bases that are being attacked. The gameplay is exactly what you would expect from a tower defense game. It offers a variety of towers and ships to defend with and constant waves of enemies to destroy. But unlike most tower defense games, it offers unique features such as powerups and different upgrades that can tilt the tide in your favor."
