Rich Fiore is an engineer who used a projection to display a game that he created on the side of his house. He used Unreal Engine to create the new game and transformed a Wii Remote into a fake gun to play with.

The purpose of the game is to use the gun to shoot the ghosts and spiders coming out of the windows of the house. Fiore even created a destructible environment that shows the walls of the house falling apart whenever it’s shot. 

In an interview with TechCrunch, Rich talked about his inspirations and where he hopes to take the game.

I honestly think that there is some major commercial viability to a project like this. Just picture all the events that you go to that would be infinitely more fun with this game. It might be difficult to adapt this to multiple environments, but the game shown in the video is just a demo. He already stated in the interview that he plans to continue working on the game and improve it. Hopefully by next Halloween this will be sold commercially.
