My brother was playing Burnout on my tag and HDD but now he wants to play Burnout with his tag [We dont care about Live Points by the way] I was told there is a way to move it but we dont know how to cause everyone is too worried about their points and just think that Im wanting to cheat, all I want to do is give my brother his game save file from my HDD to his MU and tag instead of my stuff so he can take it to friends houses so can someone tell me how to move this please?

Go to the section on his xbox where you make a gamertag. If you scroll over to the right it will say Recover Gamertag. Enter his gamertag, email, password..etc, and there you have it.

There is not a way to move anything between accounts (at least not without hacking, and this is likely to corrupt the data or worse) as data like that is registered to the account that it was made under. Sorry, but your brother will have to start over under his account.

Edit: At C...L, that would only put the account recovered onto the system, which it already is in this case.
