Hmm...Okay
First off: Mattman shut the F*** up and go cry in your corner, no one cares. There have been so many zombie movies its impossible not to accidentally rip one of them off...besides, I'm reminded more of night of the living dead :D
Second: This was far harder than the second, as has been said; but that does not make this better unfortunately. The guy may appear to be moving slowly to everyone else, but he's moving fine because of how small the map is. If it was bigger, I'd hope he was faster like in the second one. But then the one big problem comes up that I don't like in this game: It's far, FAR too easy to get cornered, and then you can't shoot half the time because it goes through them. However, that is the only thing I've noticed that isn't particularly lovable about this game, so you're doing fine despite what any naysayer may say; though I have yet to see a single one of those in the reviews :D
