Requires Battlefield 4 on Origin in order to use.

Battlefield 4 Naval Strike takes the intense and dramatic water-based combat introduced in Battlefield 4 to four all-new maps set in the South China Sea. Blow open a crashed passenger plane and capture fishing villages across the tropical Lost Islands. Drop a submarine on your foes as you infiltrate a naval base or rush between shipping docks and rocky islands on the massive Wave Breaker map. Wage war across stormy seas in the largest ocean stretch in a Battlefield map yet with Nansha Strike. Storm an abandoned cliff-side resort, or get lost in the breathtaking vistas in Operation Mortar. Naval Strike also introduces five new weapons, the amphibious hovercraft vehicle, ten assignments and the all-new Carrier Assault mode, which is an homage to the fan-favorite, Titan mode from Battlefield 2142.
