This game is a great game and really funny if you had the right music to it. What you get in the game is the mall music with ravage, bloodthirsty zombies in it. Just play some hard rock or metal with it and it will be awesome. The ai engine is very well, and still funny in some parts, I mean, you see a zombie mutilating a human in one spot, and another just hanging out in the park. This game is huge in possibilities, where you can beat the game with everything done, or you coulsd just go through the entire city and come back and get picked up by the helicopter (if you beat the game with everything done, you'll have a very nice suprise, because the games not done yet!). The horror engine is good if you are playing it for the scare, but for the laughs, its great too.
This game has something in it that it seems like in real life you can wake up and kill hundreds of zombies before breakfast, and that will be your job. It just makes it seem so natural.
This game is good to buy and to play during the night and day, no matter what, it will be scary or funny, its your choice.
