This game just got released as a beta a week or so ago and has been doing the rounds on the usual areas but haven't seen it on here.
It's based on the Slender man mythos, if anyone's not heard of him (I hadn't) it's basically this dude that stalks and kidnaps children, and if you encounter him you experience nausia, memory loss etc. He is tall, has long arms, no face and wears a suit.
Anyway enough of the BS, go and download the game. You just have to collect 8 pages dotted around various landmarks within an enclosed area of wooded area. As you collect the pages the ambeint sound grows in tension and becomes unbearable by page 5.
You are being hunted by Slender, there's only 1 of him, you have no defence, if you look at him for too long you lose, if he grabs you you lose. Your torch has limited battery and you can barely sprint for 25m, and afterward you are very slow.
I'm at work so don't have direct links to download, but it's a free game released by some genious, available on most mirror sites and is approximately 55mb there is a Windows and OSX version.
I'll post a reaction video of my friend playing later when I get chance, it even made me jump and I wasn't playing haha.
