Call of Cthulhu: Dark Corners of the Earth

It's time for you to draw upon your skills in exploration, investigation, and combat as you battle the evil incarnate. Call of Cthulhu: Dark Corners of the Earth combines both action and adventure elements into a first-person horror experience. You'll combat enemies using the environment, powerful and evil artifacts, Alien technology, and authentic 1920s weaponry. Cthulhu enemies can roam freely around the environment–opening doors and tracking you down single-handedly or in groups. A detailed damage and healing system breaks down the healing process into conditions and treatments.
