All Xbox One games will follow the same guidelines for Achievements and Gamerscore. ”On Xbox One games are games. All games follow the same policies for Achievements and Gamerscore,” a Microsoft spokesperson told XBLA Fans.
This policy came into question when Microsoft released the Achievement list for Halo: Spartan Assault, which revealed that the game will carry a Gamerscore of 1,000. In addition to a higher point count, games purchased through the Microsoft Games Store can also receive additional Achievements after their release.
