Bad Company 2, Battlefield 3 and Dragon Age: Origins are now available via Xbox One backwards compatibility, Microsoft has revealed. Sadly, the three EA titles don’t yet appear to be part of the EA Access game vault, which would make them free for subscribers.
Battlefield 3 is currently only available to those who own the disc version.
Also added to the backwards compatibility list were Ghostbusters, The Splatters, Strania and Scrap Metal.
