Could you summarise the MW2 story, please? I'd like to hear it because I totally didn't get what happened in that game, except for fighting against Russians in Washington in the end.

MW2 story....

My friend's gunna die! *rips knife out of chest and throws it into eye of baddie. Cliffhanger ensues as your other friend picks you both up in a choppa.

Basically, except for the changes I made.
