Yup – it is finally coming to backward compatibility for real.
No matter what version you have it will work from July 8th. Here is Rockstar’s official announcement:
Today we’re happy to announce that Red Dead Redemption will be released as part of Microsoft’s Xbox One Backward Compatibility program this coming Friday, July 8th.
Starting on Friday, every Red Dead Redemption Xbox 360 owner will be able to play the game directly on their Xbox One, regardless of which version of the game they own (Red Dead Redemption, Undead Nightmare and Red Dead Redemption: Game of the Year Edition). And for those who have yet to experience it, the game will be available to purchase on Friday from the Games Store on Xbox One.
I can’t wait to get into this game again. This is one of my highlights over the last decade.
