Though it was controversial in the lead-up to its release, it is hard to argue against the idea that Call of Duty: Modern Warfare 3 Zombies makes good use of its open-world concept. As disappointing as it may be to see Urzikstan reused, as it weakens CoD Zombies’ environmental storytelling, there is a lot going on within each match. Players can team up with the other players roaming around the map, complete contracts that range from cargo deliveries to bounty hunts, and travel to a number of different locales in hopes of collecting a powerful MWZ schematic. However, when it comes to enemy variety, there is always room for improvement.
