Battlefield 4 'Naval Strike' trailer teases chaotic sea-based warfare

First gameplay footage of the third DLC pack

DICE has released a new Battlefield 4 trailer teasing the chaotic water-based warfare of the upcoming DLC expansion, Naval Strike.

The new expansion pack, due in late March, will feature four new maps with a heavy focus on ship-to-ship combat, as well as five new weapons, the amphibious hovercraft vehicle, ten assignments and Carrier Assault mode.

Battlefield Premium members will receive access to Naval Strike two weeks before it goes on general sale.

In a recent Q&A, lead gameplay designer Gustav Halling explained that the greatest challenge with Naval Strike's maps was giving boats enough room to be useful and infantry enough land to fight over. DICE decided to minimize the number of land-based vehicles to keep the spotlight on sea-and-air skirmishes.

Infantry can shape these battles by opening and closing flood gates to bases, though they may find their firefights disrupted by shifting aircraft wreckage and falling submarines.

Air units will find plenty of room to manoeuvre, but helicopter pilots will have to keep their eyes out for a new threat: engineers get a new Heli-Mine gadget that can block off paths for low-flying choppers.
