I went back through the videos to see what happened.

The girl thing, I hit her, she died, and Jae shot me from about 40 yards away, in the head, and since my health was blinking red, kill instantly, given to the girl.

The second one I was real pissed about was the Gravity Hammer one, and I hit him, the note popped up that he died, and then you hear his shotgun go off and kill me.

Failure.
