''The teaser trailer for Slender: Source has lurched its way onto the internet. The Half Life 2 mode is currently being developed by indie studio Ethereal Entertainment. The mode will expand the Slender experience. The mod is a survival horror co-op game in which players work together to collect a number of dolls while avoiding the terror that is the Slenderman.''
Just in time for New Years! Blacklight Studios (Ethereal Entertainment) have released a new update concerning Faceless which had previously won Best Upcoming Mod over on Moddb.
It showcases some creepy stuff, and their own take on Slenderman has finally gotten life. It's terrifying. It also reveals a bit of the story behind the game.

Some issues have arisen in some article that have been put up by Kotaku, and Joystiq regarding Faceless as well as some concerns towards the future of the project. So, please bear with me as myself, and some devs try shining some light on everything that has happened.

Faceless (Slender: Source) developers release a video of Faceless for Halloween. It shows their Slenderman model in action, as well as it seems to be from his POV.
