I'm very sure that One tap headshot is actually a glitch in free fire but the company made it normal instead of fixing it , the aim should never go automatically to the head and that's based in the sensitivity and etc... , This destroyed the good game experience and now everyone is playing like a hacker , they should make auto aim only in body and then it can go up to head by some skills of course , if they make this fixing and optimization I promise you the game will be good as the beginning
