In single-player, gamers will experience huge environments, a playground of destruction, access to an arsenal of vehicles and the ability to direct squad mates. Taking a page from the social aspect of multiplayer gaming, the single-player mode will now track players’ progress, adding an element of persistence and friendly competition to the campaign.

The world is on the brink of chaos, China is the tinderbox and you and your squad are the inadvertent spark that could ignite a global conflict. This is Battlefield 4. As Sergeant Daniel Recker, you play as a member of an elite group of unlikely heroes known as Tombstone squad, navigating the turmoil around you as you fight to save the final hope for peace.

Expected to be available on March 25 first for Battlefield 4 Premium members (April 8 for non-Premium members), DICE has now delayed both the PC and Xbox One versions citing quality issues.

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.

The team delayed the PC version of Naval Strike because they are concerned that the combination of the pack and planned PC updates would increase performance issues on mid-range to high-end PCs. DICE is working hard to resolve that issue now. Additionally, the team decided to delay the Xbox One version of Naval Strike because they want to address issues in the animation system that hinder players from engaging targets in set circumstances using popular weapon configurations.

We know that many Battlefield 4 Premium owners wanted to play Naval Strike today. However, the team didn’t want to release the new content until they believed it was quality content.

Battlefield 4 Naval Strike introduces four all-new maps:

• Lost Islands: Blow open a crashed passenger plane and capture fishing villages across these tropical islands.
• Wave Breaker: Drop a submarine on your foes as you infiltrate a naval base or rush between shipping docks and rocky islands on this massive map.
• Nansha Strike: Wage war across stormy seas in the largest ocean stretch in a Battlefield map yet.
• Operation Mortar: Storm an abandoned cliff-side resort, or get lost in the breathtaking vistas in this map.

The Battlefield 4 Naval Strike expansion pack also introduces five new weapons, two additional gadgets, 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.
