Like the other titles in the Dead Space franchise, Dead Space 3 takes place in the 26th century. Mankind has colonized the stars but is in desperate search of new energy sources. One potential method was found in the Chixulub crater on Earth: an extraterrestrial artifact, dubbed the "Black Marker", which produces a constant electromagnetic field in defiance of the law of conservation of energy. Though human scientists hoped to harness the Black Marker for its unlimited energy potential, they soon discovered that the purpose of its field is to re-animate and mutate dead flesh, resulting in outbreaks of "Necromorphs". EarthGov immediately shut down the project, but a number of Red Markers, reverse-engineered copies of the Black Marker, had already been created and needed to be hidden; even worse, one of the project's lead researchers, Michael Altman, went public with it, promising that the Markers were sent to "make us whole" through a process called "Convergence". A religious movement, Unitology, seeks the Markers in the hopes of unlocking salvation. Isaac Clarke (Gunner Wright), the protagonist of the franchise, has already survived two outbreaks of Necromorphs, as chronicled in the first two installments of the series. He is joined in this game by Ellie Langford (Sonita Henry), who also survived the second game, as well as two EarthGov soldiers, Capt. Robert Norton (Robert Gant) and Sgt. John Carver (Ricardo Chavira), in an attempt to end the Necromorph threat once and for all.
