In the second part (Near Flint Intersection) I removed his armour using a combat shotgun but that scene has been cut from the video. And all shots did not hit his head. Only 2 were headshots (that's because his skin had short height) and rest hit him below. Even in colt only 1 bullet was hitting him at a time and the second bullet passed from the side. And I have noticed and have heard that both colt and combat shotgun work excellent even in mid range shooting. Even I saw that sousage uses colt for mid-range shooting that's why I always use colt.
And all my my guns had a great spread. I was using a pair of colts, Combat Shotgun, Tec9, AK-47 and a Sniper Rifle(did not use Sniper in any fights). All of these have a better spread and range than his Sawn-off Shotgun and deagle. And this is not our first fight. He has already killed me too many times and I had also reported him for using hacks. He used C-BUG + aimbot in LVPD just 10 mins before these clips although I did not record it. And there are more people who noticed that my aim is not stable at all. He was alone in this fight and I had nice guns so I killed him easily. In short range he always gives a Sawn-off headshot and uses Fast Reload Bug and plays on God Mode. And I am not lying at all. Even after using a FPS Adjuster I get only 20-30 fps in outer world and my ping is between 200-250. If I start using hacks my fps would go somewhere to 5-10 and the game would become unplayable. I have not much recordings of my fights but maybe my kill to death ratio that was shown in dissord by using /istats [HH].THE_MAN would prove that I get killed more times than killing players.
I still don't understand why the AntiCheat system was triggered. I was also warned once for using cheats and was kicked 2 weeks before but I had informed an admin about it and he said it was a false warning.
