A prequel to the original Dead Space, Dead Space: Extraction was a Wii-exclusive rail shooter that's been ported for release as part of the PlayStation 3 version of Dead Space 2. It tells the unpleasant tale of a group of people attempting to escape the horror of Aegis VII, only to find that things aren't all that terribly much better aboard the ISS Ishimura. After being shot down on approach, they discover that the ship is infested with hideous, twisted necromorphs and find themselves trapped in a desperate battle for survival.
