DICE and Electronic Arts have confirmed their plans for a full reveal of Battlefield 4 on March 27. Today, the studios released a teaser trailer which shows what looks like the propellers of a submarine, followed by the words "prepare 4 battle".
Another part of the same trailer was previously revealed by the official Battlefield account, which contained what looked like tank treads. Presumably, the whole trailer will have both vehicles, and perhaps a few others, when it's released later this month.
Hopefully, the studio will reveal more than just a trailer and provide us with some actual gameplay footage of Battlefield 4.
Although EA has yet to confirm release plans, the game is expected to be released on the PC, PlayStation 4 and Microsoft's unnamed next-gen platform this holiday season.
