It was quite recently, in Penumbra: Black Plague. After putting off playing it for some time, I finally got up to a point where you need an arm to activate a hand scanner, and some nice fellow offers to saw off his arm so that you can advance. Turns out that all he really wants is to saw through the door between you and him so that he can eat your brains out.
Would have been scarier if it weren't for that damn virus in your head shouting 'come at me brother' in a really annoying voice.
