《銀河戰士 Metroid Prime》（日文名：メトロイドプライム）是由Retro Studios開發，任天堂負責發行，於2002年首度推出的第一人稱動作冒險遊戲。雖然原本是在GameCube上登場，但Wii平台則透過《Metroid Prime Trilogy》合集於2009年重新推出，並針對Wii的體感功能進行完整優化，帶來更直覺的操作體驗。是《銀河戰士》系列首次採用第一人稱視角，成功將探索與戰鬥完美結合，並深深影響日後整個「第一人稱冒險」類型的發展。

劇情設定在《Metroid》與《Metroid II: Return of Samus》之間，傳奇女戰士薩姆斯·亞蘭（Samus Aran），這次她接獲銀河聯邦的任務，前往宇宙海盜佔領的軌道研究站調查異常活動。在調查過程中發現，海盜們正在研究一種名為「Phazon」的神秘放射性物質，試圖利用它進行基因改造與生物兵器開發。研究站爆炸後，薩姆斯追蹤線索來到名為「Tallon IV」的未知星球，在這裡展開探索、戰鬥與揭開Phazon秘密的孤獨冒險。

以第一人稱視角進行，但不同於傳統射擊遊戲，重心放在探索、環境解謎與裝備收集上。最大特點是充分運用Wii遙控器與Nunchuk組合的體感功能，以Nunchuk控制角色移動，以Wii遙控器自由瞄準並射擊，類似當時流行的光線槍操作感，使戰鬥更直覺且沉浸感強烈。切換不同光束、導彈、掃描器等功能也只需簡單按鍵或手勢操作，令整體節奏更加流暢。

裝備系統是遊戲核心之一，需透過探索逐步找回失落的裝備，例如雙重跳躍的「高跳靴」、穿越窄道的「球形模式」、發射強力能量的「冰凍光束」等，每獲得一項新能力，就能打開更多原本無法進入的區域，形成「能力驅動探索」的關卡設計（即Metroidvania風格）。掃描系統也是亮點，用掃描器分析環境、敵人甚至是背景故事碎片，深入了解Tallon IV星球的歷史與Phazon的真相。

戰鬥方面，注重節奏與觀察，許多敵人與Boss擁有特定弱點與攻擊模式，單靠火力猛攻無法取勝，必須靈活運用環境、裝備與自身反應。快速瞄準與自由視角讓Boss戰變得更加刺激，尤其是面對大型生物如Flaahgra、Meta Ridley等時，體感操作帶來更緊湊的臨場感。

市場評價上，在Wii版發行時依然獲得極高評價，許多評論認為即便隔多年，關卡設計、氣氛營造與系統完成度依然不輸當代新作。特別是針對體感操作的最佳化，不僅沒有破壞原本的探索節奏，反而讓射擊與操控體驗變得更加自然，令新舊玩家都能輕易投入其中。音樂與音效設計也是備受讚譽的部分，從孤寂空靈的地表音樂，到緊張刺激的Boss戰配樂，每段旋律都深刻烘托出星球探索時那種既神秘又危險的氛圍。不過，也有部分玩家指出，由於本身節奏偏慢、依賴大量回溯探索，對於喜歡快節奏動作或即時刺激的玩家而言，可能會感到略微沉悶。此外，掃描與資料蒐集對於劇情理解雖然重要，但也讓某些玩家覺得過於繁瑣，需要投入較多耐心與細心才能完整體驗世界觀。

總結來說，《Metroid Prime》Wii版是經過時間考驗，依然閃耀光芒的經典之作。以深度的探索、細膩的關卡設計、沉浸式的科幻氛圍，再加上針對體感進化的優化操作，成功將銀河戰士系列帶入新世代，並且成為Wii平台上不可錯過的重要代表作之一。如果喜歡結合射擊、探索、解謎並且擁有濃厚孤獨感的冒險遊戲，絕對值得嘗試。

Metroid Prime (Japanese title: メトロイドプライム) is a first-person action-adventure game developed by Retro Studios and published by Nintendo, first released in 2002. Originally debuting on the GameCube, it was later re-released for the Wii in 2009 as part of the Metroid Prime Trilogy collection, fully optimized for the Wii’s motion controls to deliver a more intuitive gameplay experience. It marked the Metroid series' first foray into first-person perspective, successfully combining exploration and combat, and profoundly influencing the development of the "first-person adventure" genre thereafter.

The story is set between the events of Metroid and Metroid II: Return of Samus. Legendary bounty hunter Samus Aran is assigned by the Galactic Federation to investigate suspicious activity at an orbiting research station seized by Space Pirates. During her investigation, Samus discovers that the Pirates are experimenting with a mysterious radioactive substance called Phazon, aiming to use it for genetic modification and bioweapon development. After the station's explosion, Samus follows the trail to the unknown planet Tallon IV, embarking on a solitary journey of exploration, combat, and unraveling the secrets behind Phazon.

Although presented from a first-person perspective, unlike traditional shooters, the focus is placed on exploration, environmental puzzles, and equipment-based progression. A major highlight is the extensive use of the Wii Remote and Nunchuk for motion controls: the Nunchuk handles movement, while the Wii Remote allows free aiming and shooting, providing a light-gun-like feel that made combat more intuitive and immersive. Switching between different beams, missiles, and the scanner is also streamlined through simple button presses or gestures, maintaining a smooth and natural gameplay flow.

The equipment system is one of the game’s cores. Players gradually recover lost abilities through exploration — such as the High Jump Boots for double jumping, the Morph Ball for navigating narrow passages, and the Ice Beam for powerful energy attacks. Each new upgrade unlocks access to previously unreachable areas, forming a "progression-driven exploration" structure, typical of the Metroidvania style. The scanning system is another standout feature, allowing players to analyze the environment, enemies, and lore fragments to uncover the deep history of Tallon IV and the truth behind Phazon.

Combat emphasizes rhythm and observation rather than sheer firepower. Many enemies and bosses have specific weaknesses and attack patterns that require strategic thinking, environmental use, and quick reflexes. The ability to freely aim makes boss battles especially thrilling — facing massive creatures like Flaahgra and Meta Ridley feels even more intense with motion controls adding a sense of immediacy and presence.

Upon its Wii release, Metroid Prime received high critical acclaim once again. Many reviewers noted that, even years after its original release, its level design, atmospheric storytelling, and gameplay depth were still on par with contemporary titles. The motion control optimization was particularly praised: rather than disrupting the game's original exploration pace, it made shooting and movement feel even more natural, welcoming both veteran fans and new players alike. The game’s music and sound design were also widely celebrated, perfectly capturing the eerie isolation of planetary exploration — from haunting surface melodies to heart-pounding boss battle tracks, every piece enriched the sense of mystery and danger.

However, some players noted that the game's inherently slower pace and heavy reliance on backtracking might feel tedious to those preferring fast-paced action or immediate thrills. Additionally, while scanning and collecting data is crucial for fully understanding the story, some players found it somewhat tedious, requiring patience and attention to detail to truly appreciate the world-building.

In conclusion, the Wii version of Metroid Prime stands as a timeless classic that continues to shine even years after its debut. With its deep exploration, intricate level design, immersive sci-fi atmosphere, and refined motion control enhancements, it successfully ushered the Metroid series into a new era, becoming one of the must-play titles on the Wii platform. For those who enjoy adventures that blend shooting, exploration, and puzzles with a strong sense of solitude, Metroid Prime remains an experience well worth trying.
