I don't like it cuz it's not realistic at all. I've played everyone of them except BO3 and I didn't like them also I highly doubt that you got 100 kills on average a game. I don't like them cuz they keep wasting time on things and they shouldn't keep going in the future they should go in the past cuz it gets boring after about an hour or so. They make stuff up as they go and they put more effort into there zombies mode (which is the only thing I like) than there actual story and there multiplayer
