The biggest shortcoming in this version of the game is the amount of content you get. With only one map available, there will never be much variation in your strategy. However, with dozens of achievements up for grabs and online leaderboards to compete on, there's definitely some replay value here. World at War: Zombies is a great port of the extremely successful multiplayer mode from Call of Duty: World at War. The lack of content, high price point, and occasional connection issues with the servers are somewhat disappointing, but gunning zombies with your buddies is still a blast.
