Call of Duty: Modern Warfare 3 for Wii doesn't have split screen because the Wii doesn't have enough RAM to handle split screen.
on xbox 36o you can play split screen online
Yes. Four player split-screen local Multiplayer.
Simply go on multiplayer then click local and finally click split screen.
You can't. Try modding split screen/single player. If you meant modding for splits screen/single player (Like infinite ammo,jump hieght,disable AI spawn) use Modio.
You can play solo or split screen offline, and private/public xbox live matches online needless to say, it is maximum 2 players though.
Go to multiplayer, then go to split screen.
No only on campaign is split screen
Go to the main menu in mw3 and go to special ops (It's on the left of the screen)

you can have split screen off line , but can not have two people playing on xboxlive with split screen.
