So i got this game today and I have tried the first mission 6 or 7 times and die every rime. First I had it on stalker difficulty but then changed it to novice. I will unload clip after clip of ammunition all seemingly accurately and I have not yet killed anyone. I don't understand the problem. One time I was inches from one of them and I fired a whole clip into him and he proceeded to kill me while I was reloading.
