A new trailer for Battlefield 4 follows the recent mini-tease with an actual tease, as the clip runs a full 20 seconds (break out the popcorn) and concludes with word once again to expect the full version of this trailer on March 27th. In the meantime the clip shows a ship's propeller spinning up, which goes with the trailer's title, "Prepare 4 Battle: Sea," to further suggest the next installment in DICE's military series will feature an increased emphasis on naval combat.
