A serial code to activate Battlefield 4 Naval Strike DLC on your EA account.
Battlefield 4 Naval Strike takes the intense and dramatic water-based combat introduced in Battlefield 4 to the next level with a new amphibious vehicle and 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.
You'll be able to download the game through Origin only. Not for STEAM.
