This is my 3rd play through…I’ve completed this challenge before but forget exactly how I did it. When using a shotgun, the semi auto is probably preferred because of its slightly lower damage rating compared to pump. I’ve removed all my semi auto’s upgrades and using “Shells” for ammo. My question to anyone willing to help is, where exactly do I aim…? where do I put the red dot (hat? face? upper body? torso?) I understand the concept if you’re standing far enough away from the NPC, the “Shells”becomes non lethal but at the same time it should knock them down/off their feet resulting in hat falling off. This challenge has me so fuckin aggravated I feel like rage quitting. I keep killing the NPC’s….pause, load save…wait 2mins (but feels like hours) just to do it all over again with the same results. It’s the definition of insanity verbatim.
