@hayhor In this case with the present state of this game being dominated by cheaters this is more than likely being done through mods.
Considering that people slide toward you just absorbing your shots without taking damage, and they hipfire landing a perfect headshot that downs you much faster than legit gunshots, this is more than likely cheating. I just want to make sure there is no way to do it before I start reporting people for it. Maybe if the cheaters have a second person, maybe one operating a mouse while another holds a controller they could time it someway, but I'm guessing it's being done with illegal keybinds the way they used to tap strafe with controller, and they combine this with cheats that have aimbot/rapid fire/zero recoil like the beam cheat.
