look for Nicole. The ship is overrun by Necromorphs, forcing Isaac to defend himself by weaponizing his mining tools and "Resource Integration Gear" (RIG) spacesuit capabilities. Due to the Red Marker's influence, Isaac experiences recurring visions of Nicole, who guides him to return the Marker to the planet. Towards the end of the game, it is revealed that one of the rescue team members, Kendra Daniels, is a double agent. She betrays Isaac, but is killed by a large Necromorph creature before she can escape, while Isaac commandeers her ship and escapes Aegis VII after defeating the creature and allowing the Marker to be destroyed by a sabotage attempt he had initiated earlier. The sole survivor of the entire ordeal, Isaac soon hears something behind him and looks back to see a horrific hallucination of Nicole. Dead Space 2 Dead Space 2 reveals that Isaac has become mentally disturbed and unstable after he destroyed the Red Marker on Aegis VII, and that he was captured by EarthGov and taken to the Sprawl, a massive space-station built into the remains of Titan, Saturn's largest moon. Once there, EarthGov scientists extract information from his mind to build another Marker, and he is later confined to a hospital on the Sprawl due to a dementia-like mental illness caused by the first Marker. A Necromorph outbreak in the Sprawl instigated by the Marker copy soon occurs, thrusting Isaac into a struggle to survive the Necromorph epidemic. Haunted by hallucinations of the deceased Nicole Brennan, Isaac manages to destroy the Marker copy and undo its influence on his mind. Isaac succeeds in escaping with another survivor, Ellie Langford, before the explosive destruction of the station, and goes into hiding from EarthGov authorities as his mind still retains information about the Markers. Dead Space 3 Dead Space 3 occurs a few years later. While Isaac Clarke and Ellie Langford returned to Earth and dated for a while, their relationship fell apart. As he is struggling with the breakup in his apartment on the moon, Unitologists led by Jacob Danik activate a Marker near the colony, causing a Necromorph outbreak. Isaac is rescued and enlisted by EarthGov soldiers to help locate Langford, who had traveled to Tau Volantis, one of Earth's oldest off-world colonies, in search of the true origins of the Markers and a means to stop the Necromorph scourge once and for all.
