The Specializations have been e-mailed to players who played Halo 4 before 11/20/12. I was one of those players, and recieved the email. However, when my older brother entered the code, the only account that recieved the Specializations was his (Him, my little brother, and I were all signed in), so I was unable to actually get any other Specializations other than Wetworks and Operator. I’m SR-43, but I no longer have any incentive to rank up because I cannot choose the Specialization I wanted. I thought I would get it, but I didn’t.
