Battlefield 4's Naval Strike DLC is coming on March 25th for Premium members. As previously detailed, Naval Strike adds four new maps set in the South China Sea: the Lost Islands, Wake Breaker, Nansha Strike, and Operation Mortar.
As expected, there's new vehicles, including the amphibious hovercraft, which enables travel between land and water. There's also new weapons and gadgets. Perhaps the biggest addition offered by the add-on is the reintroduction of Titan Mode from Battlefield 2142, now dubbed "Carrier Assault." In BF4, you'll have to work together to take down an aircraft carrier of the enemy team by launching missiles.
Here's the first gameplay trailer:
