The goal in first-person horror/terror Slender is to find 8 creepy manuscripts about the paranormal creature Slender Man and avoid going insane. The more directly the player views Slender Man and the closer he is, the faster your sanity will drain. He appears rather startlingly in-game, like old-school Michael Meyers from Halloween.

The Slender Man myth started from a Something Awful thread of fabricated paranormal images. Apparently, the creature has made his rounds in several games, but Hadley/Parsec Productions' stressful game has people talking.

[EDIT:] If you wish to brave Slender, here are the current download links for Mac and Windows.

I consciously avoided turning around while preparing this blog post and trying Slender. I may just go to sleep here.
