The trend of free Battlefield expansions continues.

Update: The DLC is now free on PC through Origin, as well as the PlayStation Store in North America.

Europe should get it later today with the store update.

Original story: EA has made the Battlefield 4 add-on Naval Strike available to download for free on Xbox One, for Gold members.

This is done as part of an ongoing promotion to celebrate the Battlefield series. So far, we’ve seen a number of Battlefield 4 as well as Battlefield Hardline expansions get discounted to $0 across all platforms.

At the time of writing, only the Xbox One version has received the discount. PC and PlayStation 4 will no doubt follow later today.

We’ll update the story as soon as we get word on other platforms.
