Just recently there's been a server based on the game Slender,the game is surprisingly fun and well made i recommend you bring friends to assist you in escaping.(trailer here (

HOW TO PLAY. This game is similar to slender as you go around and find randomly placed notes as you journey through the forest....and find notes the game gets increasingly harder you'll find the notes on rocks trees in certain buildings and areas.....and as you retrieve all notes and place the ripped notes together you can escape and get one of the games 3 different ending none of which i will spoil....
It's really fun and i think you should try it it's pretty scary..and i recommend that you turn of sharders and go full screen (it makes it much more ominous with shaders)But before you start you need to go into rtb and type in Blank and download both blank faces...otherwise he will have a blockhead face.And you also need to turn on download music and sounds in your options so you can hear the custom sounds....and music (preview of the music here
