Bungie - I currently have 2 beta codes for use, but I'm only getting 1 option. I mainly want to use it for my Xbox 1 when it comes to production but for Beta purpose, I'd like to try it first on my PS3 on the 17th. Please let me know if there's a way to use one code for PS3 and another for Xbox One. How do I select which beta code goes to a platform??
