Story:

Modern Warfare 2 is set several years after the conclusion of Call of Duty 4. Sergeant "Soap" MacTavish will return as a non-playable character, and has been promoted to captain in the Special Air Service. MacTavish will lead an elite, multinational commando unit, Task Force 141, to counter the resurgent Russian Ultra nationalist organization. The group is now led by Vladimir Makarov, a former associate of Imran Zakhaev with his own nationalistic ambitions. Makarov has been portraying Zakhaev's death as an act of martyrdom to garner support for his cause, and has built a strong power base in Russia over the years. In response to the threat posed by Makarov, the global community established Task Force 141 to stop him. The player will take on the role of Task Force member Sgt. Gary "Roach" Sanderson.


Multiplayer Features:

- A "Special Forces" mode will be featured in Modern Warfare 2, comparable to the "Mile High Club" epilogue mission in Call of Duty 4: Modern Warfare, consisting of isolated missions in a variety of settings unrelated to the campaign story.
