Dead Space: Extraction is a 2009 rail shooter co-developed by Visceral Games and Eurocom and published by Electronic Arts for the Wii. A port for PlayStation 3 was released in 2011 alongside Dead Space 2. A spin-off within the Dead Space series and a prequel to the original game, the story follows survivors from the Aegis VII mining colony as the planet and newly-arrived ship USG Ishimura is overrun by deadly monsters called Necromorphs. Gameplay involves going through scripted sequences with different characters, using assigned weapons to kill Necromorphs by severing their limbs. Each version respectively supported the Wii Zapper and PlayStation Move peripherals.

Conceived during the development of Dead Space, production began in 2008 using Eurocom's EngineX game engine. Electronic Arts treated it as a test for mature games in the Wii gaming market. The aim was to create a survival horror experience within the genre and hardware limitations. The script was written by Antony Johnston, who worked on the original game and its expanded media. Jason Graves and Don Veca respectively returned as composer and audio director. The original release met with poor sales but good reviews, with critics praising its gameplay and use of the Dead Space setting while faulting pacing issues and a lack of content. Reviewers of the PS3 port praised its Move usage, but faulted the low graphical quality.

Dead Space: Extraction is a science fiction rail shooter and is viewed from a first-person perspective. Taking the role of multiple characters across the campaign, the player navigates through the Aegis VII colony and the mining ship Ishimura from a first-person cinematic perspective. The original Wii version controls using the Wii Remote and Nunchuk, incorporating both motion controls and an option to use the Wii Zapper. In the PlayStation 3 (PS3) port, the controls are altered to support both the DualShock controller and PlayStation Move. In contrast to the diegetic UI design of the original game, players can press a controller button to display weapon slots, current ammunition and health in the screen corners.

The campaign is split into ten chapters, with progress dictated by the narrative, though in some sections the player is allowed to freely direct the camera or choose routes through environments. The narrative is told in real-time, using a combination of in-engine cutscenes, and video and audio logs picked up within the environment. Gameplay is similar to a light gun shooter; enemies approach the player and are shot using the equipped weapon. The main enemies of the game, Necromorphs, can only be killed by severing their limbs. Up to ten weapons can be found, with two different firing modes per gun. The default Rivet Gun, which has unlimited ammunition, is always set to one of the weapon slots. The others are filled with weapons picked up during progress through a level. Two abilities used by the player are Stasis, which slows object motion for a short time, and Kinesis, which allows the player character to pick up and throw or move objects.

Each chapter gives players a rating based on their performance, awarding stars used to upgrade the player's abilities and weapons. Upgrades and ammunition can also be found within the environment. There are four difficulty modes, with the lowest being "Normal" and the highest being "Impossible". The two highest difficulties are unlocked upon completing the campaign. Both versions of Extraction feature local cooperative multiplayer. Players can drop in at any point during both the campaign and the challenge missions. Both players can take down Necromorphs, take turns on puzzles, and divide between different tasks during certain set pieces.

Dead Space: Extraction takes place in the year 2508, centuries after humanity narrowly escaped extinction due to resource depletion by "cracking" planets to extract their resources in a three-year process. The events of Extraction play out prior to the events of Dead Space, and in parallel to the prequel comic and the tie-in movie Dead Space: Downfall. During the second year of an illegal mining operation on the planet Aegis VII funded by the Church of Unitology, the colonists discover a monolith-like artifact they identify as a Marker, an object sacred to the Unitologists' beliefs. In reality, the Marker is a copy of an alien object that triggers the destruction of both the colony and the associated mining ship USG Ishimura using reanimated mutated corpses referred to as "Necromorphs".

The game follows several characters as they escape the Aegis VII colony onto the Ishimura. They are colony detective Nathan McNeill; Ishimura soldier Gabe Weller, who is less affected by the Marker; Lexine Murdoch, a colony resident who can likewise resist the Marker's influence and softens its impact on those close to her; Warren Eckhardt, an executive from the Ishimura; and Ishimura doctor Karen Hollwell. The opening section follows Sam Caldwell, an Aegis VII miner. Nicole Brennan, a central character from Dead Space, appears as a supporting character.

A team from the Aegis VII colony including Sam Caldwell transport the Marker into the colony. During the transport, the crew suffer hallucinations, and Caldwell kills his teammates when they seemingly go mad and attack him. After receiving a call from his fiancée Lexine about a mass suicide of Unitologists, Caldwell is shot dead by a security squad led by McNeill, who perceived his behaviour as an insane rampage.
