i live with 3 other people and we got bought an xbox 360 for christmas but i'll be moving out soon and wanna get my own 360 but all my achievements are on the current 360. is there a way of migrating them onto a new 360 or will i have to start again?

i'm a new 360 user so apologise if this is a dumb question

Are you on Xbox Live? If so, all you have to do is recover your gamertag to your new console, and all your achievements should be intact.

Otherwise, you would need a memory card or HDD transfer cable.

You can if the account that has the achievements is a Live account (can be a Silver account). If so, when you create a new profile on a different 360, simply choose 'recover Gamertag'. Usually takes about 20 minutes.

i don't have live no but i'm planning on getting it very soon so that shouldn't be a problem, thanks guys

No problem, but you can just make it a free Silver account if all you want to do is transfer your Gamerscore.

Like people have said you can recover your gamertag on a new console. This does not transfer your game saves. You will need a Memory card to transfer those. I had to do this when I switched from a 20 to 60 gig drive.

Get a Memory card.
