Set three weeks before the events of the original Dead Space, the story begins with a small group of space colonists on Aegis VII experiencing the origins of the Necromorph infection, which begins after the excavation of The Marker from the planet and bringing it aboard the Ishimura.

The game was originally released on disc for the Wii in 2009 and later released on the PlayStation 3 and PSN in conjunction with Dead Space 2. Electronic Arts chose to market this entry as a "guided first-person experience," though the game's level of interactivity is not that different from the average on-rails shooter. Dead Space Extraction is a prequel to the original Dead Space that swaps out the third person perspective for a guided, on-rails shooting experience.
