Dead Space: Extraction

Dead Space Extraction is a first-person rail shooter introducing new enemies, characters, weapons and environments to the dead space series. Players also have some degree of control over the camera. The game uses the pointer function of the wii remote for aiming at enemies and can also be controlled through the wii zapper. Twisting the Wii Remote or Wii Zapper activates a weapon's secondary firing mode, and swinging the Nunchuck (or shaking the zapper) can perform a melee attack or shake off enemies that have grabbed onto the player. Players can use a kinesis option at any time to make objects float, draw closer, or throw them at enemies. Kinesis can also be used to grab flying projectiles and fire them back.

 The story begins with a small crew of miners, among them a man named Sam Caldwell, who are helping to extract the Red Marker from Aegis VII. The crew begins to suffer hallucinations, including Sam, who begins killing his crewmates in what may or may not be self-defense. Before he can escape, a P-Sec squad arrives and kills him.
Some time later, Detective Nathan McNeill, who is working on the case file of the rampage, meets an old friend, Gabriel Weller, now serving on the Ishimura. Upon arrival, the two discover that this outbreak has spread to the entire colony and they are attacked by Necromorphs. They also discover Lexine Murdoch, Sam's girlfriend (as seen in a short prologue), and agree to take her to safety. The group races to find a shuttle and eventually find one in the Megavents, thanks to a man named Warren Eckhardt, an executive from the mining company. The four of them fly to the Ishimura for help but are warned to return to the surface. The group refuses which results in the Ishimura shooting them down with its cannons, causing the shuttle to crash into the Ishimura and forcing the group to spacewalk to a nearby airlock.

After entering the Ishimura, the group discovers the ship itself is infested with Necromorphs. As they attempt to move to the bridge, which they believe will be safer, they encounter Nicole Brennan in the medical bay who elects to stay behind in case anyone else arrives. The rest of the group continues on but they fall into the sewage system, where Lexine is attacked by Swarmers and pulled into a water tank; the group assumes she has died. Dr. Karen Howell discovers Lexine, who has somehow survived, and the two find McNeill, Eckhardt, and Weller. McNeill, Weller, and Lexine continue on while Howell attempts to shut down the sewerage system, guarded by Eckhardt. While Howell berates Eckhardt for replacing staff with fanatical Unitologists, she is attacked by a Necromorph tentacle. Eckhardt flees and locks the door behind him. When he finds the others, Eckhardt lies, saying Howell locked the door in order to sacrifice her life for the group.
In order to search for a shuttle to get off the Ishimura, McNeill and Lexine split up from Weller and Eckhardt to search multiple shuttle bays. Weller and Eckhardt find a shuttle but Weller catches Eckhardt finishing a recording of a message to a member of the Church of Unitology. Weller watches the message; Eckhardt says that he was sent to find a person who was immune to the effects of the Marker, and who could protect others from its effects as well, and he believes that Lexine is that person. He also explains that he arranged Howell's death because she was beginning to suspect his intentions. When Weller is done watching the message, Eckhardt shoots Weller and tells him of his plans, only to be killed by a Necromorph himself. McNeill and Lexine find Weller and escape on the shuttle right after McNeill shuts down the power to the cannons on the Ishimura that were preventing them from leaving, although he had to cut off his arm in the process. As they escape, they hear a transmission from the USG Kellion. Lexine tries to warn them away but they do not receive the message.
In an epilogue, Lexine is attacked from behind by a Necromorph. The scene gives the impression that McNeill (who had been seeing things and hearing voices, just as all infected do) has transformed into the Necromorph and is attacking Lexine. One can see that the ship she is being attacked on is the shuttlecraft the three protagonists had boarded. At the last moment, she grabs a pistol and aims it at the Necromorph. The scene ends with the muzzle of the gun flashing.
