The Battlefield 4 website has launched, showing a teaser background and asking you to come back March 27th. As you move your mouse around the website, it is as if you are wiping your finger on a fogged up window. An image can be made out if you move your mouse fast enough but the fog comes back quickly.
However, the more people who sign up, the more EA/DICE will reveal. So far what can be made out behind the fogged glass is some sort of tank and maybe the outline of a city. With more fan participation maybe finer details can be picked up, like what city we might be seeing or if that is really a tank at all. Check out the website here.
