It's great when a game throws you a curved ball. This has been in development for ages (often a bad sign), but Call of Cthulhu: Dark Corners of the Earth is like venturing into a theme park house of horrors run by Hannibal Lecter and Papa Lazarou. It's a twisted, horrifying shooter that's aiming for Doom levels of nastiness.
Based on the 1920s horror-fiction of HP Lovecraft, Call of Cthulhu is more about playing on fears of the unknown than drooling six-eyed monsters. Which means that when the six-eyed monsters do appear, the shock is even greater. Your fears actually manifest themselves on screen too, with your character suffering from hallucinations and panic attacks directly proportional to how scary things get. Even when we were just opening a door, the expectation of what lay behind it made the camera go out of focus and swing about in terror, as if it wanted to escape more than we did.
And with good reason, too - with all kinds of bloodthirsty clammy-skinned maniacs hiding in the shadows and bizarre fish-creatures bursting up through the floorboards, this game is a consistent, dusk-coloured nightmare. Add the nerve-shredding death sequences, where everything turns grey and slows down as the game becomes a desperate fight to take as many yellow-toothed madmen with you before they swarm in for the kill... Trust us, come review, this'll knock you out the water.
