when you get hit on the back of the head by a blunt weapon like a baseball bat, your screen should go black, and then you cant move for 30-60 seconds depending on how strong of a weapon it is. a sledge hammer would knock you out for 60 seconds and a weaker weapon like a flashlight would knock you out for 30. your body can be dragged by other players and you can be hand cuffed. if someone injects you with an adrenaline needle, you should instantly wake up. if you are injected with morphine, you should be be unconscious for 25 more seconds. but you can only be given morphine twice to prevent you from being unconscious for ever. this would also give people more of a reason to carry adrenaline and morphine on them.
edit: got flagged for “off-topic” wtf
this would also lessen the ammount of KOS, as people could knock them out, take the items they want from them, and then they can leave them there with the leftovers they didn’t need so they dont lose all their stuff, only what the guy who hit them wants
