Deus Ex: Human Revolution was the first backward compatible title for Xbox One to support multiple discs and users can expect more "multi-disc scenarios" in the future.
Multiple Xbox 360 disc support added to Xbox One backward compatibility
This is according to a comment made by Major Nelson on reddit who said the backwards compatibility engineers worked hard to bring the multi-disc game to Xbox One.
Microsoft said fans were asking for the feature, and its engineers listened. They "found a solution to enable" the feature which will help "further expand the titles included in Xbox One Backward Compatibility."
Xbox 360 title Deus Ex: Human Revolution - Director's Cut, which spans two discs, was made available for Xbox One earlier this week.
