Light Gun Shooter Game

Intro

Full Metal Exorcist is intended to be a game in the form of a horror light gun game inspired by the House of the Dead and Resident Evil light gun games. It is a one-player game where the player stars as a Robocop-like non-human robot exorcist, controlled remotely by a human priest, that goes through a variety of locations “exorcising” spiritual and demonic enemies with a series of guns and simple cinematic actions.
