When I written my impression, I had played 2 mission and now I did 2 more official of the story and one battle of the campaign.
I've set the game at normal and I claim it's very hard to impossible.
I guess it must another plot to reduce me because I doubt I have the same version as everybody. I'd need to set the game at easy maybe and there is no way that I'm going to do that.
So I won't play this. And I can't wait to see the guys that can beat that game in COD. Seriously...
