AAX-G49X-7AMY-YAPY-PARB there you go. It might say it's already been used or something like that, but it should work. Already gave out one, guy said it didnt work at first, but he checked his inventory thingy and it gave it to him. So there you go man.
just read your post about DLC achievements and had to give you a personal message to say i completely agree and get really annoyed at these people whining about DLC breaking achievement limit rules and ruining 100% complete ratios etc! might seem random but i have been going mad over it lol
