When playing with a friend who has alot of the BL achievments and you dont have many yourself sometimes if your lucky a few or your friends achievments might rub off on you. But this must be done in system link or it wont work. It happened to me on one of my old profiles that i used.
Does not work all the time, and for the slow people out there it does not work if you already have the achievments!
