Battlefield 4's Major Expansions Are All Free on Xbox
EA is currently offering the selection of major expansions for Battlefield 4 on Xbox One and Xbox 360 for free following the 'Road to Battlefield 1' event that took place recently.
You don't need Xbox Live Gold to pick these deals up, but you do need to subscribe in order to use them. Once you've got the expansions, they're yours to keep forever so you might as well considering the expansions are usually $15 each.
The expansions are China Rising (X360/XBONE), Second Assault (X360/XBONE), Naval Strike (X360/XBONE), Dragon's Teeth (X360/XBONE), and Final Stand (X360/XBONE).
