Hellboy: The Science of Evil is a video game based on the comic book character of the same name. It was released for the PlayStation 3, Xbox 360 and PlayStation Portable on June 24, 2008 in North America, followed by an August 15 release in Europe and August 28 release in Australia.Players control Hellboy in a third-person perspective as they progress through a series of levels broken up into six chapters. Levels consist of separate stages and routes occupied by multiple groups of enemies that differ between chapters. In most cases, all enemies in the current area must be defeated in order to move to the next phase of the chapter, with ghostly barriers of smoke blocking paths while foes remain present. To combat opponents, Hellboy uses his stone "right hand of doom" for most hand to hand combat situations, with heavy and quick attacks that can be mixed together for varied combinations.
