Black-ops will have an offline version of the multiplayer, with AI opposition. Also you will be able to level up as if you were online =)
Yes.
If you're offline, you're not connected to anyone but your own console, so you can't play multiplayer.
if you mean offline then no sorry well if it was i would be playing it but i am sorry :(
no , but call of duty modern warfare reflex (cod4) has
You cant exactly make a gun in black ops, but you can customize a gun in multiplayer create a class mode and play online (or offline) with the customized gun.
Combat training if u want to play offline
no you can play solo offline but you will need broadband iff you want to play multiplayer online.you can play split-screen offline though
You go to Multiplayer, then local, then Splitscreen- not sure otherwise if that doesn't work.
There is. Just go to settings and make the "Number of enemies" higher.
At the main menu you go to multiplayer, then go to local. Then you set up the game.
In Black Ops, you don't get an offline multiplayer account. It only shows your playercard from your online account. So the answer to your question is; you can't level up on your Black Ops splitscreen account because you don't get splitscreen accounts in Black Ops.
Long Campaign games likr ratchet and clank and world of war are good. and if u have black ops a can verse computers offline but it might get boring.
