- "This is Temple. The bridge is fucked. I don't know what went on in there, but I'm not sticking around in case whatever did it comes back. I'm heading for Hydroponics, to find Elizabeth."
- —Jacob, in the audio log Temple on the Bridge
Jacob Temple was an engineer who worked aboard the USG Ishimura. He was mentioned as Acting Chief Engineer in various audio logs. His logs chronicled his journey throughout the disaster aboard the ship.
The Second Aegis VII Incident
During the early stages of the Necromorph outbreak, Jacob and his Engineering crew are trying to maintain the Ishimura's engine room. However, as time passed by and the infection spreaded, the members of his crew started showing signs of dementia. After realizing the danger, Jacob abandoned his position on the Engineering Deck and he searched for his girlfriend named Elizabeth Cross. Jacob frequently left the audio logs of his journey that Isaac Clarke found throughout the ship. He eventually reunited with Elizabeth and the two attempted to escape from the vessel together.
Their reunion was cut short when they are intercepted by Challus Mercer. The two are gagged and Elizabeth was killed after Mercer rammed a metal spike into her head which was a process that was used by the Unitologists in preparation of the Necromorph transformation. Temple was killed shortly afterward by the same method in front of Isaac who could only stand by and watch.
- Temple is only seen alive in one chapter. All of the other "Encounters" consisted of collecting his audio logs.
- Jacob can be seen in Dead Space 2 during the "Previously on Dead Space" montage.
- Jacob Temple's journey as it was experienced through his audio logs resembled Isaac Clarke's in a number of ways. He seems to travel roughly the same path as Isaac, often attempting to fix the very problems that Isaac eventually fixes. He is also seeking his girlfriend named Elizabeth Cross and according to the audio logs, he reunited with her on the Mining Deck which was the same deck which Isaac sees Nicole again. In fact, it could be that Isaac is only about a chapter or two behind Jacob Temple's journey after the Necromorph infestation.
- It is impossible to save Temple. The door to the room where he is being held remains in "Standby" mode until Mercer exits the room after killing Temple.
