First of all, Great idea to send codes to via email (only to those who played early). I thought one of the cool parts about Halo 4 was supposed to be that you had a CHOICE in which specialization you wanted. Now because my contact email was linked to two accounts (one of which was automatically created by Xbox.com and cannot be deleted), my code was redeemed on the account that is worthless, never even played a second of Halo on it. Nothing I can do to change it. Thanks 343! Keep up the great work!
