I've been playing the game for some time now. I don't understand why so many bad reviews. I enjoy playing the zombies and all the additional research and equipments you can receive. I really do enjoy playing multiplier, but it could be difficult at times. One of the reason why I gave it five stars out of six.Is because they need better skins and weapons skins. Let's add some cool characters like mortal kombat or something. Wouldn't it be pretty cool to run around with zub zero or scorpion. How about street fighter and b guile and have american camo weapons. Just an example, I think would be pretty cool.
