What is this and how do people hab golden things around their erkennungsmarke ?

Du kannst kein english oder??
Naja jedenfalls kriegt man das wenn man die limited edition gekauft hat bzw vorbestellt hat.
Wenn du die normale version hast, kriegst es nicht ^^

You can change frames of the dog tag by going to Operative Status>Dog Tags> and then pressing square button on your PS3 Controller and each type of dog tags like mystery, medals and awards have differen frames. And also Golden Frames are from pre-ordering game from certain shops.
