Microsofts Marc Whitten har bekræftet, at spil, der udkommer både på Xbox 360 og Xbox One, har separate achievements, og at spillerne kan øge deres gamerscore ved at spille de samme titler på begge platforme.
I et interview med IGN forklarer Whitten hvordan achievements fungerer på de to generationer af konsoller:
"Every game has its own set of achievements, so if you're playing Call of Duty: Ghosts on Xbox 360 and on Xbox One, you can earn a separate set of Gamerscore in each game. But on the Xbox One version, you're getting a much richer set of features, such as seeing your achievements progress on the Xbox One console, being able to unlock new achievements throughout the year, and earning real prizes inside and outside of the game. Xbox One also enables a new concept of challenges, where games will be offering special time-based opportunities to earn various goals and collect the rewards".
