Call of Duty: Modern Warfare 3 picks up where Modern Warfare 2 left off with the invasion of Manhattan by Russian forces. You will blaze through 20 action-packed missions located in England, Russia, America, Germany, and France, playing as a Russian Federal Protective Services agent, an SAS Operative and a tank gunner. The Spec-Ops missions from MW2 will make a return, split into "Mission" and "Survival" modes. Also, Call of Duty: MW3 will have the amazing CoD-style multiplayer that you have come to known.
There are a lot of things I regrted after I finished this game, but it weren't the same kind of regret you can have when you finished a wonderful game. In the previous Modern Warfare games, some characters didn't have to die, that was enough, and in MW3, there is the state of th art of the "can't die character" who finaly dies!
