Call of Cthulhu: Dark Corners of the Earth combines an action-horror game with a fairly realistic and immersive first-person shooter, with good stealth elements. The game is based on the works of H. P. Lovecraft, author of `The Call of Cthulhu` and progenitor of the Cthulhu Mythos, and in particular the game is a reimagining of Lovecraft's 1936 novella The Shadow Over Innsmouth. Set mostly in the year 1922, the story follows Jack Walters, a mentally unstable private detective hired to investigate a disappearance case in Innsmouth, a strange and mysterious town that has cut itself from the rest of the United States.
