While i'm a good lover of single player games, co-op has become more and more of a selling point on games today for me as, well, it's usually just funner this way.

Now, I had thought of picking up this game until I heard that Co-op wasn't actually campaign or free mode, but more mission like. And me, trying to save myself the time of stumbling across spoilers or something, could someone kindly say what co-op is like? Preferably add on a bit on how it is split screen as well.
