Afraid of Monsters
Afraid of Monsters is a Half Life mod that turns Half Life into an amazing survival horror game. In the game you play as David Leatherhoff, a guy addicted to drugs. Recently, David Leatherhoff’s been suffering from halucinations. Afraid of Monster is based on Half Life and so is a first person shooter, but this mod takes Half Life into the realm of survival horror.
Highly violent third person shooter set in space with tons of scary aliens and death scenes.
