World of Warships, the new game from World of Tanks maker Wargaming, comes out on 17th September 2015.
The free-to-download naval battle game launches with four classes of ships and over 80 historic vessels, including the battleship Yamato and aircraft carrier Midway.
Two million people got involved in the open beta, Wargaming said, spending an average of three hours a day playing. So you'd expect there will be plenty of people online when the game launches later this month.
The video, below, offers a good look at what World of Warships is all about.
