Oh sorry guys about that I figured the beta was over but did not know. I would have loved to take the armor myself but I figured I would not get the game in time so there goes that. Heres hoping I do not have to pay for it myself when I finally do get the game. You are welcome TokyoStomp hope you enjoy the armor looks awesome I would if I had the game.
I think that code was for registering for in-game items in GCI, not the beta. You would eventually get an email with a PSN code for items if you bought the game. I don't know if the promotion is over or not.
