@bosbarret Replace the man with knife with 2 regenerating humanoid zombies. It's rather hard to land 2 headshots one after another at that range (he had about 1 second if they charge right away, give or take) and with that mindset.
He just emptied his mag (clip) in the head of the already killed hound, since he wanted the MC to stop yelling. Apparently he didn't have magic reload skills, and empty guns are considerably less dangerous.
Damn convenient if the key gets absorbed into his body.
