I just finished it on the #2 difficulty. Too easy, but that first level where you have to take down the police station by yourself was killing me on the next higher level because I didn't get the controls. The controls still suck. That is my biggest complaint with this game. Give me a quick-aim button and I am happy. Once you have some muldoons it as not that big of an issue. By the time I got to the assassination mission, I had figured out the controls and was OK. However, I can't even begin to describe how frustrating it is to have some Soviet Soldier right in front of you and you can't seem to point your weapon at him. It was the close-combat that was the worst. When you had some distance it was OK. If a guy comes around the corner right in front of you, you just point and unload some ammo into him. No need to take careful aim at that range.
