Passage: Electronic Arts announced Dead Space in September 2007. The game was developed at their studio in Redwood Shores, California. A 2006 rumor had suggested that the studio was working on a System Shock sequel. This was later confirmed by Dead Space designers Ben Wanat and Wright Bagwell, who stated that it was originally intended to be System Shock 3, before the release of Resident Evil 4 inspired them to go back to the drawing board and develop it into something more along those lines. The game's executive producer, Glen Schofield, said that the team aimed to create something 'darker and creepier' than their previous titles: "We are all such huge fans of the horror and sci-fi genres; we wanted to create the most terrifying game we could, and keep the player on the edge of their seat the entire time." The design team reportedly spent time analyzing a wide variety of horror films in order to find inspiration for in-game scares.Previews drew attention to the high levels of gore and violence in the game, in particular the tactic of "strategic dismemberment", emphasized by Schofield as "the primary theme of Dead Space". The Necromorphs cannot be subdued by a single shot, rather they have to be incapacitated by shooting off their tentacles and appendages. A series of developer diaries released for the game had featured one episode about the system, in which developers mentioned that using conventional tactics, such as aiming for the head or torso, would only serve to aggravate some of the Necromorphs. In order to make the corpses look more realistic, the development team studied photos of car crash victims and war scenes.
