Isaac aided Kendra and Hammond as they repaired the Ishimura, slowed by the onslaught of the Necromorphs. The attack separated Isaac from the others. Only Kendra Daniells, Zach Hammond, and Isaac survived, while both of the pilots were killed. Shortly after abandoning their shuttle the group was ambushed by Necromorphs. Upon finding the Ishimura the Kellion was struck by a meteorite and forced to crash land in the Ishimura. Isaac Clarke was one of the five crew members aboard USG Kellion when it was assigned to repair the communications aboard the USG Ishimura. He lived with Nicole Brennan, his girlfriend, but his career stagnated about the same time she was promoted to the Ishimura.

Isaac attempted to reunite with his father, but he’d gone missing and his personnel files were classified. He enlisted in the service and was praised for his skill. He went to a lesser-known college than the one he strived for, due to financial issues, but graduated with high honors and took after his father and became a system engineer. His mother gave all her money to the church rather than finance her son’s education. Losing her husband made his mother, Octavia Clarke, into a devout Unitologist. Isaac’s father, Paul Clarke, was a renowned ship designer who left for space when Isaac was only a child. He is assigned to respond to the distress signal from the USG Ishimura, the first of the planet cracking line of ships. At the time of events on the Ishimura, he is 43 years old. Isaac Clarke, the protagonist of Dead Space, is a systems engineer who works for the Concordance Extraction Corporation (C.E.C).
