Known urban legend. the Slender Man is a mythical creature with a tall, thin body and a blank face. He can shorten and lengthen his limbs at will, and has powers that can induce paranoia, insomnia, and coughing fits. He can teleport at will, and generally resides in forests shrouded in blackness. “Not much is known, as no specific information has been found about origins,” explains one fan site that details the legend, “but his objective and habitat are made very clear. He has the need to kidnap children.”

The less you know about this game until you play it, the better. (Also, do yourself a favor and avoid watching any of the reaction videos until you’ve gone through a few playthroughs.)
