Call of Duty zombies is in my opinion one of the better games there is. It actually has to take a lot of strategy to play it because you have to know where your going and what your going to do when somebody important dies. Sometimes you don't even know that your the one that is keeping the team alive most of the time. Also it is fun because you have to communicate and listen to where the team is going. Most of the time with a really good team you can get to high levels really fast and also get a lot of money just by killing zombies.
