A frequently retweeted tweet says the physical PC version of Metal Gear Solid V: The Phantom Pain does not actually contain the game, but rather a 9 MB stub Steam installer on an otherwise empty Blu-ray disc. This was found on Destructoid where they mention a the game will be a 28 GB download, though they don't say how they arrived at that figure, nor do they indicate why this tweet is being so widely accepted as fact, though we have no specific reason to believe it isn't accurate.
