Will halo 1 ans 2 work on an xbox-360?
Yes. The Xbox 360 is backwards-compatible with all original Xbox games.
Ok yay!!!! 2Ed. Dues an xbox-360 come with xbox-live? If not haw much is it?
It comes with one month of free online. Then sliver, which gives you all the downloads and friends options is free for as long as you own the console.
Gold just gives you online play along with everything sliver has. I think it runs around $6 a month.
