Is there possibility to play regular single player missions in co-op mode or are there specific co-op levels built for it?
They are seperate levels from the single player, A seperate story with two different operatives that takes place while sam is out doing the chaos theory missions (there is a point in one of the levels where the two stories tie together sorta (kinda funny)
CT coop gets my vote for most innovative gameplay idea this year. Coop mode is soooooooooo badass. Just make sure you play with a friend, and not some random asshole.
