《絕命異次元 逃亡記》（英文名：Dead Space: Extraction，日文名：デッドスペース エクストラクション）是由EA Redwood Shores 與Eurocom開發、Electronic Arts發行的Wii專用射擊遊戲，於2009年推出，是知名科幻驚悚系列《Dead Space》的前傳作品。為Wii平台特別量身打造，改以「軌道射擊（rail shooter）」的形式呈現，結合Wii獨特的體感操作與沉浸式氛圍，帶來與系列主作截然不同的遊玩體驗。

故事劇情設定在《Dead Space》初代事件的前一年，地點則是在Aegis VII殖民地與USG Ishimura號太空船上。玩家扮演一群生還者，包括偵探Nathan McNeill、警衛Gabe Weller以及科學考察家Lexine Murdoch等角色，他們在發現神秘異星遺物「Marker」後，整個殖民地陷入瘋狂與死亡的詭異狀態。居民紛紛發狂自殘，一種稱為「死靈變異體（Necromorph）」的恐怖生命體也開始屠殺人類。為了逃出生天，必須在充滿血腥與混亂的環境中求生，揭露事件背後的真相。劇情強調角色之間的互動與情感衝突，穿插大量過場動畫與語音對白，敘事節奏緊湊，氛圍濃厚，是一款極具電影感的驚悚遊戲。

在操作系統方面，充分運用Wii的體感控制特色。以第一人稱視角呈現，採用軌道式設計，無法自行移動角色，只能專注於瞄準與擊殺敵人，類似《死亡之屋（House of the Dead）》這類街機風格射擊遊戲。使用Wii Remote進行瞄準與射擊，Nunchuk則用於切換武器或啟動特殊功能，如發射震波、使用「靜止模組（Stasis）」讓敵人或物體減速等。部分場景還會要求進行即時反應操作（QTE），例如劃動Wii遙控器躲避攻擊、強行打開門鎖或操縱重力裝置。也有升級系統，可強化武器性能，並收集日誌、音訊檔案等支線素材，補完劇情。

視覺與聲音設計方面，即使在Wii硬體限制下，依然展現出系列一貫的昏暗、美術細緻的科幻恐怖風格。燈光與陰影營造出壓迫感極強的環境，搭配耳語、尖叫、機械雜音與突如其來的配樂，讓人長時間處於神經緊繃的驚悚氛圍中。由於故事發生於封閉太空船與殖民基地之中，密閉空間與突襲式敵人出現手法成功營造出原作恐怖感，同時又透過節奏緩急與角色劇情推進保持吸引力。

市場評價方面，發售後獲得廣泛好評，尤其在遊戲媒體間評價頗高。《IGN》給予8.5分，稱讚是「Wii平台罕見的成熟恐怖作品」，並認為劇情與射擊體驗相當緊湊出色。《GameSpot》則指出雖然遊戲類型由自由移動變成軌道射擊，但透過優秀的敘事手法與創新的互動演出，依然成功延續《Dead Space》的恐怖與世界觀。特別是合作模式支援雙人同時遊玩，使得本作在家庭主機平台上更具娛樂性與重玩價值。

然而，部分玩家也指出軌道射擊的設計限制探索與自由度，對於喜愛原作那種開放式解謎與資源管理的玩家而言，或許不夠耐玩。此外，畫面表現雖然在Wii上已屬上乘，但與當時HD主機的《Dead Space》相比，仍有一定落差。儘管如此，依然被視為Wii平台上最優秀的恐怖射擊遊戲之一，也是該系列中少數有深度角色描寫與劇情厚度的作品。

總結來說，這是將系列世界觀成功轉化為體感射擊形式的前傳之作。雖然犧牲自由移動與開放性，但換來的是更精緻的故事節奏與恐怖演出。對於Wii玩家來說，這是一款少有的成熟向、劇情導向且極具氣氛的射擊遊戲，也為《Dead Space》的宇宙增添豐富背景與情感深度。

Dead Space: Extraction (Japanese title: デッドスペース エクストラクション) is a rail shooter developed by EA Redwood Shores and Eurocom, and published by Electronic Arts exclusively for the Wii in 2009. Serving as a prequel to the renowned sci-fi horror series Dead Space, this game was specifically tailored for the Wii platform, utilizing its unique motion controls and immersive interface to deliver a distinctly different gameplay experience from the main titles in the franchise.

The story is set one year before the events of the original Dead Space, taking place on the Aegis VII colony and the USG Ishimura spacecraft. Players assume the roles of various survivors, including detective Nathan McNeill, security officer Gabe Weller, and scientific researcher Lexine Murdoch. After discovering the mysterious alien artifact known as the "Marker," the colony descends into madness and death. Civilians begin to exhibit psychotic, self-destructive behavior, and horrific creatures called Necromorphs start massacring the population. To survive, the characters must navigate the blood-soaked chaos, uncover the truth behind the outbreak, and escape alive. The narrative focuses heavily on the relationships and emotional conflicts between characters, with numerous cinematic cutscenes and fully voiced dialogues, creating a suspenseful, film-like storytelling atmosphere.

In terms of gameplay mechanics, Dead Space: Extraction fully embraces the Wii’s motion-control capabilities. The game is presented from a first-person perspective and follows a rail shooter format, meaning players cannot control character movement freely but must focus solely on aiming and shooting, similar to classic arcade shooters like House of the Dead. The Wii Remote is used to aim and shoot, while the Nunchuk enables players to switch weapons or activate special abilities, such as deploying shockwaves or using the "Stasis Module" to slow enemies or moving objects. Some scenes incorporate quick-time events (QTEs), requiring swift Wii Remote gestures to dodge attacks, unlock doors, or manipulate gravity-based puzzles. An upgrade system allows players to improve weapon performance, and optional logs and audio files can be collected to enhance the game’s lore.

Visually and audibly, despite the Wii’s hardware limitations, the game successfully captures the dark, atmospheric sci-fi horror aesthetic the Dead Space series is known for. Dim lighting, dramatic shadows, and eerie environmental design build a strong sense of claustrophobia and tension. The sound design features unsettling whispers, sudden shrieks, mechanical hums, and jarring music cues, constantly keeping players on edge. The setting within confined spaces like derelict ships and claustrophobic colony halls further heightens the sense of dread, while the pacing alternates between tense quiet moments and sudden action sequences to keep players engaged.

Upon release, Dead Space: Extraction received widespread critical acclaim, particularly from gaming media. IGN awarded the game an 8.5 out of 10, praising it as a "rare mature horror experience on the Wii" and highlighting its gripping narrative and intense shooting gameplay. GameSpot noted that although the switch from free movement to rail shooting might seem restrictive, the game still succeeded in maintaining the franchise’s signature horror atmosphere and immersive world through clever storytelling and interactive presentation. The inclusion of a two-player co-op mode added replay value and made the game more accessible for home console play, especially among friends or families.

However, some players criticized the rail shooter format for limiting exploration and freedom, which might disappoint fans of the original game’s open-ended puzzles and resource management. While the visual presentation was strong for the Wii, it naturally fell short of the high-definition fidelity seen in the mainline Dead Space games on other consoles of the time. Nevertheless, Dead Space: Extraction remains one of the best horror shooter titles on the Wii, notable for its depth of character development and narrative richness within the series.

In conclusion, Dead Space: Extraction is a well-crafted prequel that successfully adapts the Dead Space universe into a motion-controlled rail shooter. While it sacrifices freedom of movement and exploration, it gains tightly-paced storytelling and intense horror presentation. For Wii players, this title stands out as a rare, mature-themed, story-driven shooter that also adds emotional weight and rich lore to the Dead Space mythos.
