EA have launched a teaser site and video for the upcoming Battlefield 4. The site features a cool rain on window pane effect – you can wipe the window using your mouse to get a brief glimpse at the action on the other side of the window. Swing by and check out the teaser site here.

A brief video has also been released which seems to suggest that sea battle will be a much bigger part of the new game.

More will be revealed on March 27th. In the meantime, what improvements are on your wishlist?
