Unfortunately, said trailer is 100% pre-rendered and in no way, shape, or form indicative of gameplay besides the very superficial image of battleships turning their guns menacingly and firing, while fighters sputter to life of the decks of aircraft carriers. Oh and there's an exploding volcano in there also. Because of course there is.
This trailer does, however, mark World of Warships'
debut to the public and if there's on thing I know about such things (which there isn't), it's that exploding volcanoes = public unforgetability.
