I just called my local gamestop and they gave me a 16-character-long code over the phone. How exactly do you put it in?

He also said that although they are giving out early access codes, they have most likely closed the access for the actual demo! I have no idea what to do. I hope I am wrong but it seems almost pointless to try anymore and just wait for the public release.

Any help is greatly appreciated.

enter it in as you would enterinn microsoft points or how ever you were redeem something for the psn

but go to the area on the dashboard thats like redeeming a poitns card for the xbox 360
