My brother is coming over for the long weekend, and I don't want him wrecking my K/D ratio when he plays MW2 all day while I'm at work. He has his own XBL account (my old one), is there a way to copy over his account to my xbox, just for the duration of his trip, he'll want to have his account back on his xbox when he gets home.
If not, I guess he's bringing over his xbox, haha.
