Battleship trailer revealed

I’ve watched the trailer, but I’m still no closer to discovering how Universal have managed to make a full length film out of an 80s board game. There’s battleships certainly, but no-one is saying “E4 – kapow”. There’s a blonde girl, there’s Rihanna and Liam Neeson – there also appear to be unexplained ships that look a bit like Transformers. Still, any trailer which responds to a query about what weapons have to be fired with the line “All weapons” is fine by me. Connect 4 next?
