I think this game was awesome.  If you didn't play the mission No Russian you missed a good twist in the plot.  The mission Loose Ends was a hard but during the download part it also had a good twist at the end.  The Gulag was a fun place for a mission.  The ending was awesome too.  It might just been my computer but some times computers moved slowly. Multiplayer was awesome to I haven't gotten to prestige yet but so far it has been awesome.  I love how unlike World at War you can use shotguns as secondary weapons not primary.  Special Ops was awesome too . . . I haven't beat all those either.  The Musem bonus level is awesome too.
