i played coop with a friend the whole campaign.
what i find odd is that there is no cutscenes for multiplayer.
the worst part of it was the weird ass level design, the later levels get a bit better as it become a little more linear instead of the labyrinth of the first to second episode, it wraps it up a rather alright experience, good for a history lesson but frankly there are better games out there that offer a better experience overall.
