My gamer tag is Big Daddy1445. I pre-ordered Halo 4 and picked it up 11/06/2012. I played it live before 11:59:59 pm Eastern time 11/20/2012. I am over 17 years of age and live in the United States. I did not receive the code(s) via my Microsoft-registered email account to allow me to pursue the optional specializations other than Operator and Wetworks, which I have completed. Please send me the code(s) to allow me to pursue the other specializations. Thanks.
