It is impossible to transfer anything that you've earned in spit screen mode to Xbox LIVE without modifying the game.
No but you can do splitscreen.
No guest can be allowed to join in xbox live, but if you to want to play splitscreen that is possilble by going to Multiplayer: then Splitscreen ~ Koolface
Yep, and WaW has splitscreen offline as well.
No, but you can play with other players around the world if you have xbox live gold.
Yup. You can either do it on splitscreen with two controllers, or over Xbox Live.
you can do it by going on the main menu n that but beware that you can only do it by xbox live and not splitscreen
Nah man you can't, which me and my brother think is total bs. But you can play splitscreen on live with two different xbox live accounts
Is xbox live possible with a dongle
You can't. You must earn them all again on Xbox Live, as well as the ranks, perks, weapons and emblems. Infnity Ward and Microsoft did not allow players to do this because players could cheat to aquire everything, which they do anyway by using hacked servers.
