The Battleship is master of the seas and the most powerful (and expensive) unit in Civilization Revolution. It is a stand-alone in that lesser units such as Cruisers do not upgrade to it if Leonardo's Workshop is built. While not as fast as the Cruiser, the Battleship more than compensates through sheer power. Bring your Submarines when battling a Battleship, as their cheap cost and high attack value are the best way to efficiently take down these monsters of the sea.
