Call Of Duty Modern Warfare 3 Offline Multiplayer Crack

I don't have Xbox live or even internet, but I would still like to create my own class (as far as I know you have to be on level 4 for that and you have to be online to level up) on COD 4. I also have modern warfare 3 and in there you can level up in the local multiplayer. I was wondering if you can do the same in the first game.
