Unpopular opinion: not every shooter needs head shots

[aileron]

I'm mostly going to echo what others have said... If it's supposed to be realistic then a head shot to the face or to someone without a helmet should kill almost always and always incapacitate. I'm not even sure how much a helmet would do, depends on the era, the type of weapon and the type of helmet I guess. That being said, who says video games are supposed to be realistic? They're just supposed to be fun.
