You can pick up Battlefield 4's Second Assault expansion free right now on Xbox One and Xbox 360.
More free Battlefield DLC is now available as part of EA's "Road to Battlefield 1" campaign. The latest freebie is Battlefield 4's Second Assault expansion, which normally sells for $15. Right now, it's only available for free on Xbox One and Xbox 360, but if this follows with past offers, PlayStation and PC players can eventually expect to get in on the promotion as well.
Originally released in December 2013, Second Assault includes four multiplayer maps, all of which are new versions of ones from Battlefield 3. These include Operation Metro, Caspian Border, Gulf of Oman, and Operation Firestorm. Second Assault also adds five new weapons and 10 additional assignments.
Xbox One (4.42 GB)
Xbox 360 (1.34 GB)
The Second Assault page on EA's Origin site still lists the content at $15, while the same is true for the PlayStation Store pages. We'll update this post with more details on those platforms when it's made available.
In May, EA made Battlefield 4's Final Stand DLC free as part of the Road to Battlefield 1 campaign. That offer, and others that came before it--for Battlefield 4 and Battlefield Hardline alike--was good for one week only.
Battlefield 1 comes out in October for PS4, Xbox One, and PC. For more, check out this rundown of all of the confirmed maps and modes.
