I gave my self a custom challenge today set for 3 hours and i need to get 15 headshots.
When i look at my progress it says 14/15 i am positive i have gotten at least 30 kills from swat. I dont know whats wrong please help.
Not every kill is a headshot, you need to get he medal, maybe your buddy shot them once or twice in the body and you just hit them in the upper body and they died.
