I love having that silly game to play with friends... but I must say, I hate the special zombies, they pretty much ruin it for me. I love getting headshots or even armored zombies that will very logically resist more bullets... but the ones with machine guns... nope, hate them. They aren't even armored, but the only part that can get damaged is the head and you can't even aim in peace as they also fire toward you. Maybe with more friends to act as a distraction, that could be okay... but in single or two players, this is dreadful... and adding a player needs another game and another console.
