Dead Space 2: Severed reintroduces Gabe Weller and Lexine Murdoch, two of the lead characters who originally appeared in the critically acclaimed Dead Space Extraction. In a story that runs parallel to Isaac's blood-curdling adventure in Dead Space 2, players will take on the role of Weller as he fights against his own onslaught of Necromorphs, attempting to save both himself and Lexine.
