That is a good question, I know once you login to the game you can choose what to redeem in the social menu. I would suggest contacting 2k support about itBraining is hard for me, is the early adopter pack single redemption only?
I won't be able to log in to my main on Xbox before the 27th but have a chance to at least play a bit on the PS4. If I log in on my Shift, would everything I've done for B3 then be tied to the PS4 account?
As I said, braining hurts
