Can I have my code?!?!?!

So it’s pretty aggravating that I’ve reached level 70 can’t level up or unlock other armor specializations and I’ve been playing since the game came out. I know the code was sent out but I never received it and theres no way of notating 343 directly. I would appreciate getting the code to unlock those specializations and be able to level up.

Please somebody help me out with this I know there’s guys out there with the same problem

No new codes are being given out, the promotion is over. The specialisations will eventually be given to everyone.

There is no estimate as to when that is.

EDIT: Very early next year. https://twitter.com/bsangel/status/279077757844082688
