DICE has released a full teaser video for Battlefield 4 to go with the small little GIF teaser it offered earlier this week.

The teaser shows a full length version of what was in GIF and features a submarine starting up its engines before the Prepare 4 Battle logo comes up. Does this mean that we’re going to get underwater engagements in Battlefield 4? It would certainly be a move away from the land and air battles of Battlefield 3.

The full debut trailer for Battlefield 4 will go live on March 27 and the game’s official reveal is set to happen at an EA event in San Francisco on March 26. Last night an official teaser site for the game went live, offering a free dog tag for Battlefield 3 players.
