no I've checked all over the place and i don't think it does, though it says 2 player co-op on the box.

Absolutely infact it is highly recommended by Ubisoft
No, you can not do splitscreen.
Cant play it offline with the new DRM 2, you need a always on internet connection to play this game even just for solo gameplay.
You can't, modern warfare 2 has only one player online but it has splitscreen which is only local play.
to play two player split screen on modern warfare to you must first choose multiplayer at the main menu. you then choose splitscreen and then you set up a game and play each other. you can also play 4 player but you unfortunately cant play two player splitscreen whilst online (halo you can !!!) hope this helps
