Yes.
There is a new feature called Combat Training on Black Ops.
It is there to help you to worm your way into the multiplayer battefield without your online stats suffering.
Now then, to access this you must be connected to the internet.
You then go to Multiplayer and go onto the top option (I think it's online or something.) then choose the lobby as Combat Training.
Combat Training has its own ranking system but is SEPERATE to the mulitplayer online.
Hope this helps!
