The single-player and campaign modes are actually really great stuff. But like nearly all Call of Duty games, that is the content you'll breeze through within your first week playing if even for just a few hours a day. The bulk of the ride ends up being multiplayer and zombies and that is where the problems really lie. This is a game that I'm sure will eventually get the extra content, balancing, and bugs worked out along a series of patches and end up being much better than it is today. But unfortunately the buggy, laggy, unbalanced, and content-sparse game we get at launch is the only one I was given to review. And the balance of the excellent single-player with below average multiplayer ends up for an average overall experience.
