Slender: The Eight Pages, formerly known as Slender is a free experimental game developed by Parsec Productions. It was released as a beta in June 2012 for Windows and Mac OS X.
Lots of people are talking about this game like it's "da best horror game evar!11".
Here's what this game REALLY has to offer: Boring gameplay. Bad level design. Bad graphics. Cheesy Slenderman model. Boring jumpscares. Not scary in the slightest.
