I guess it was only a matter of time before someone "capitalized" on Slender and made some sort of parody for it.
As many of you know, Slender is a first-person horror game that pits the players against a man wearing a white-mask. The player can't fight the Slender Man, so they have to run away. In order to complete the "levels" you have to find notes that are scattered about the area. But, that is certainly hard to do with this creepy thing following you around.
AV Byte is responsible for this little gem. If you listen closely, I think they are imitating the Spiderman theme a bit, but I am not positive.
If you could talk to the Slender Man, what would you say?
