In the most appropriate piece of retailer exclusive downloadable content ever, Amazon Japan shoppers get a special cardboard box as DLC when purchasing Metal Gear Solid V: Ground Zeroes. What kind of cardboard box is it? Konami won’t say because the DLC code isn’t for Ground Zeroes, it’s actually for use with Metal Gear Solid V: The Phantom Pain.
As of now, the special cardboard box, presumably an item Snake can hide in, is only available from Amazon Japan.
Metal Gear Solid V: Ground Zeroes comes out in North America on March 18 for PS3, PS4, Xbox 360, and Xbox One.
