Call of Duty Black Ops is four player split-screen, and 2 can play split-screen online.
The best one would have to be Call of Duty 3 on PlayStation 2. Yes you can go online on it.
All of the newer call of duty games can be played online. I've been playing since Call of Duty 4, and they are making Call of Duty 8 right now, and all have been online enabled.
yes, call of duty world at war has online. you go into multiplayer and click play online.
I'd say Call of Duty 3 because there is no online mode so he won't be harassed by other players. Also the language won't be as offensive in the regular game as it would be online with other people talking to him.
