"Corrosion casts the player in the role of Sheriff Alex Truman as he attempts to break the monotony of life by piecing together the history and origins of a disturbed and unidentified car crash victim. Set entirely underneath an idyllic country farmhouse, in the deserted and claustrophobic confines of a mysterious and secret underground complex, players will explore a place nobody knew existed, and uncover a twisted past that gets more and more terrifying with every corner turned, every door opened, and every note read."
