I believe the beta unlocks should transfer over. Like the dog tag you unlock. I have a triple kill dog tag from an air stomp, and probably will never be able to do that again. So for like $10 everything from the beta transfers over like the level, prestiges, attachments, etc. And automatically, the dog tags and things like that. i have over 60 dog tags, and about 10+ hours in the beta and that is a lot of time to put back into a game to not get back all the things i have unlocked.

if you want to add me
The only thing you will keep is your Beta/Alpha dog tag. Nothing else is carried over.
