Ordinarily, you toss a video like this on YouTube, and every comment shouts it down as fake. But anyone who's played indie horror hit Amnesia: The Dark Descent knows this guy's skin-crawling, pupil-dilating, sphincter-clenching, headphone-grabbing reactions are on the level.

Amnesia was really scarry but after the first time I died and barely suffered any consequences from it the game got less scarier.
I wish the game would punish the player more for dying.
