I haven't played 4. But in a number of threads here I've read people being upset about a lack of real life guns and guns not working like they do in real life relating to reloading and stuff in posts made by people who know about guns.
Now I don't know much about guns. If you showed me one I could probably tell you which end the bullets shoot out of and that would be pretty much it. I probably wouldn't be able to identify a specific model of gun or what country it was made in or anything else about it.
So I was wondering what do people who don't know much about guns who have played 4 think of the guns in 4?
