This is actually happening. Hollywood has somehow managed to take what originally started as a pencil and paper guessing game that predates World War I and made Battleship into a summer blockbuster that has absolutely nothing to do with the original game. And now, it's going to be a videogame.
There's a new trailer out today, and it shows off (you guessed it) battleships. But not the in-game battleships, these are CG battleships. In fact, the only gameplay footage in the trailer is a two second clip of what looks like a flying alien machine rising out of the water and another two second clip of the first-person shooter part. Because that's what Battleship was always intended to be about.
