From now until September 19, you can pick up every expansion pack for Battlefield 4 for the low, low price of free. For those who were steadfast in their resolve to "wait until the DLCs are super cheap" your time has come... three years after the game's release. Huzzah!
As we approach the end of the road, we’ve got something really special for anyone looking to get some Battlefield 4 action in before Battlefield 1 ships on October 21. From September 14 until September 19, every expansion pack for Battlefield 4 is now available for free. That’s right, all of ‘em. And we’ve even got themed Community Missions to go along with them.

That includes China Rising, Second Assault, Naval Strike, Dragon's Teeth, and Final Stand. Links to all expansions on all platforms can be found at the Road to Battlefield 1 site. You had best act fast here because the offer ends on the 19th!
