The game starts out with a transmission between Isaac Clarke and his girlfriend Nicole Brennan, whose suicide was a major plot twist in the original game.

The game was released on Xbox 360, Playstation 3, and PC on January 25th, 2011.

Isaac Clarke now has lines of dialogue, however, the familiar formula of the original remains unchanged consisting of claustrophobic encounters in dark corridors as well as in open zero-G environments, tactical dismemberment with hard hitting engineering tools and lots of heart-pounding scares throughout. In Dead Space 2, Isaac takes the fight to the Necromorphs, suggesting a much more aggressive style of gameplay than what was seen in the original Dead Space.

The church of Unitology and the ominous Earth Government continue to play an important role in Isaac's fight against the Necromorphs. Following his encounter with the marker in the first game, Isaac is now plagued by disturbing visions. Set three years after the first game, the player once again takes control of Isaac Clarke as he continues his fight against the Necromorph threat.
