Metal Gear Solid 5: Ground Zeroes will contain exclusive in-game content for Xbox One, according to a tease from Spike TV host Geoff Keighley.
The announcement was made during Spike's Times Square launch special for Xbox One.
Other than this slight nugget, no other information was provided.
The PS4 versions of the game will also contain PlayStation 4 exclusive content in which you play as Naked Snake taking photographs and recreating scenes which will then unlock the ability to play as classic Solid Snake.
Metal Gear Solid: Ground Zeroes is coming to PS3, PS4, Xbox 360 and Xbox One in northern spring 2014. It is a prequel to Metal Gear Solid 5: The Phantom Pain.
