You had to preorder the game from GAMESTOP.
That was the only way to have Ghost's mask from MW2.
For the new ghosts mask you have to buy the season pass.
I have the hardend edition that came with the game and season pass (digital version).
I have the ghosts mask, and some patches and backgrounds.
Plus the Free Fall map.
I did not preorder my game from Gamestop so I don't have the MW2 mask.
I got my copy on the PSN store. Pre-order.
