BF4 Bonus Gold Battlepack Opening
I got my code on my email and did all the steps. I entered the code finally on PSN and it lets me download it but I don't see it anywhere. I know you can open battlepacks at battlepack section, but ...
I recommend going into your download history in the PSN and re-downloading the battlepack, then open BF4, go to my Soldier, then battlepacks and see if it shows up after the redownload and restarting BF4.
