Is it possible to enable the developer console for single player?

I remember that there was a way to enable the console for MW2 and black ops, but then MW3 came along and there was no way to enable it. Is it possible for this game?

Use cheat engine to find the value. But Treyarch Anti-cheat now scans zmobies and single player, so don't bother, you will get banned fully from the game.
