On March 25, Battlefield 4 Premium members on consoles will be able to experience the ultimate sea-to-sea warfare in the third expansion pack for Battlefield 4. 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 while introducing a new game mode and vehicle.
However, we are delaying the launch of Battlefield 4 Naval Strike on PC. We’ve detected an issue and it needs to be solved. Quality is our number one priority and we will not release Battlefield 4 Naval Strike on PC until we feel it meets the highest quality level possible. Once we have a confirmed date for PC, we’ll be sure to update those players on our official channels. We appreciate your patience and look forward to seeing everyone on the Battlefield.
