Slender: The Arrival (2013) from Blue Isle Studios
“One of the most terrifying games in recent memory.”
From GameSpot.com:
“As a sort-of myth born on the Internet, Slender Man is probably one of the first genuinely compelling monsters to grace pop culture in a long time. The related games and their variants and mods, as well as the stories and YouTube videos surrounding them, show the genesis of 21st century folklore. While a little rough around the edges, The Arrival is fascinating because it plays on modern fears through a modern medium. For that, it has managed to breathe new life into a genre once thought dead. Slender is not an experience you will soon forget, and at $10, is priced just about right for its short length. Just be sure to play at night with headphones for full effect. Good luck.”
