EA have added a second Expansion Pack to the list of EA Access titles to download for a limited time.
Battlefield 4 Naval Strike is a sea-based level with amphibious vehicles set in the South China Sea.
You’ll need to  visit the EA Access app on Xbox One before September 3 to claim your gift, though, as after that date it will disappear.  Anyone who claims before that date will be able to keep the pack forever.
Battlefield 4 Naval Strike has been a quality addition to the series. Battlefield 4 has been a very good game since day one. Looking forward to starwars battlefront being the newest addition.
