As a standalone title it's successful both online and off, but it pales in comparison to it's predecessors.
Platform: Xbox 360
Developer: Infinity Ward
Released: November 8, 2011
Gameplay:
Relatively the same online multiplayer which has made the series what it is, but with too few additions to make it a worthwhile upgrade. Very disappointing campaign which does its job of wrapping up the plot of the first two games, and nothing else.
Offline: C
Online: B
Visuals:
Identical to the previous entry. Still good, but should be better two years later.
Then: (Current)
Now: A-
Audio:
No noticeable differences from previous titles. A smaller cast of voice actors, but still great individually.
Sound: A-
Music: B
