I don't think this is real as the Multiplayer menu never has the main advertising/disc cover picture.
And the main menu never plays the reveal trailer music.... Pretty sure this is fake.
apart from the fact when you switched from the main menu to the multiplayer menu the music continued to play. On all the other cods the music stopped! so im pretty sure its fake
quote from the article: "we wanted to confirm just in case so we reached out to one of our Infinity Ward contacts and they confirmed it is indeed fake."
