I go to my neighbour's house to play Modern Warfare, since I'm jealous of you guys. Man playing that scene at the Moscow Airport, crazy! So I did the level 3 times.
Ah, you are talking about the level known as "No Russian". That level was removed from some countries versions on the game. I've played it twice myself, but that's because I accidental wiped out all my MW2 game saves last Friday and I'm doing it again. I beat it on normal and I'm almost finished hardened. All I need to do is "veteran" and I'll have finally played a game through all levels (not counting beginner).
I also lost all my 2 player Co-Op missions, which sucks but I play with buddy Mikey and he and I have so much fun playing those together that it's not that big deal.
What I was most worried about losing was my online score. That's taken me at least 6 months to get. Thankfully, the MW2 servers store that data, so I'm still Prestige 2, level 27.
Man I love this game.
