@believer258: I started the game on Hard and died constantly from the turrets. When I play it again (which I have no idea when will be) I'll definitely give it another shot now that I know just what's going on.
I'm trying to change the new Offline/Online (such as co-op, head tracking, etc.) features on a wiki page but it won't let me. The options stay grayed out and there's no way to change them. I've got over 1000 wiki points, if that's anything.
I think 4 was the best constructed and probably most entertaining from a game standpoint, tho it really lacked 3's emotional depth and character development. Not many really good character moments in this episode, I thought.
