Isaac Clarke, no longer suffering from hallucinations or the effects from the previous games, is awoken by Captain Robert Norton and Sergeant John Carver of the Earth Defense Force explaining that they require Isaac's help to find Ellie Langford, the pilot from Dead Space 2, who has gone missing with her team. The trio is soon attacked by Unitologist soldiers led by Jacob Danik, leader of the Unitology cult movement, but escape. Once in orbit around the frozen planet of Tau Volantis their ship breaks apart due to the countless mines left in orbit around the planet. Isaac and Carver team up with Ellie, Jennifer Santos, and Austin Buckell as they attempt to end the Necromorph threat once and for all by turning off the machine. Danik, using the Codex, turns off the Machine himself, rather than destroy the machine it causes the Convergence Event to resume. As the incomplete Necromorph Moon, free of the Machine's control, descends towards Tau Volantis collecting the up markers, Isaac Clarke and John Carver make their last stand.
