During the final sizzle reel of the the Xbox One count down launch event Microsoft showcased something rather surprising (or maybe not too surprising?): a quick splash screen with the logo of Metal Gear Solid V: Ground Zeroes and the wording "Exclusive Xbox Content"

This, of course, means that the nostalgic mission that will grace the PlayStation versions of the game will only represent one side of the coin, with Microsoft getting its own share of exclusive content, and no one getting to play the whole thing...unless you buy the game twice, obviously.
