So the new Xbox One backward compatible list for this month has yet to release and we are about to finish this month. So on Reddit people have found The Witcher 2: Assassin’s of Kings free on Xbox.com now we have not heard a confirmation on if this is a GWG title and a BC title. The assumption is that it could be both but you never know, a mistake could happen. You can download it right now and i highly suggest you do it before it gets taken down. Especially for all you that are not familiar with the series, this could be a good start before starting The Witcher 3.
Stay tuned on more information on Games with Gold and Backward Compatibility on Xbox One!
