The game will release at the end of November. The first chapter will be free, with the other chapters to follow costing a fee. The game looks entertaining enough to warrant a look at upon release. Also, the developers have launched a Kickstarter to support development, and add more features to the game. It's a pity they missed the Halloween window, but those who have to visit their families on Thanksgiving will tell you, the end of November can be pretty frightening in its own regard.
