Battlefield 4: Naval Strike rolls out for non-Premium members on April 15

Battlefield 4's third expansion pack, Naval Strike, will be released to all non-Premium members on April 15, DICE has announced. The new expansion, which emphasizes sea-to-sea warfare and water-based combat though four new maps set in the South China Sea, was released in late March for all premium members after a brief delay.

"We want to give all Premium members their two-week early access regardless of what platform they play on," DICE said of the non-Premium release.

Battlefield 4: Naval Strike introduces four new maps: Lost Islands, Nansha Strike, Wave Breaker, and Operation Mortar; a new amphibious ACV Hovercraft; and Carrier Assault, an homage to BAttlefield 2142's Titan mode.
