Gamers can purchase a disc-less dual-license digital version of Call of Duty: Ghosts. This version will include the Xbox 360 digital version of Call of Duty: Ghosts, as well as the Xbox One digital version of Call of Duty: Ghosts - linked and unlocked via a user's Xbox Live gamertag.
All you have to do is purchase your Digital Combo wait for delivery and then visit xbox.com and login with your account (this is the same as your Xbox Live gamer tag account).
Click 'redeem code' and enter the 25-digit code found in the Call of Duty: Ghosts Digital Combo box, then click Confirm.
Please note: This is not a boxed game - it is a box containing a digital download code ONLY.
