Developed by Psionic, Ghostscape 3D is the latest horror title to get a Steam Greenlight campaign. Created using Unity and available as a work in progress title through the Google store for Android or PC online using the Unity web player; Ghostscape 3D is set in an old haunted house that will challenge you and of course try to scare you.
The developer mentions that Ghostscape will have lots of items to collect, puzzles and scary goings on, with the entire game including the art and music by himself. It will be interesting to see just how scary this game will actually be, as coming from a Paranormal Investigator I've yet to play ANY game that is truly scary.
