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.

From June 21 to June 28, you can get Battlefield 4 Second Assault for free, featuring four of the most fan-favorite maps from Battlefield 3. Don’t wait too long, though, because you only have until June 28 to snag these throwback maps.

You’ll take a step back in time with Battlefield 4 Second Assault, featuring four fan-favorite maps from Battlefield 3 – Operation Metro, Caspian Border, Gulf of Oman, and Operation Firestorm, reimagined with Frostbite 3 graphics and Battlefield 4 gameplay.
