《惡靈古堡4 加強版》（Biohazard 4 Wii Edition）是卡普空推出的經典生存恐怖遊戲《惡靈古堡4》的改良版本，於2007年在任天堂 Wii平台發行。原作於2005 年在 GameCube上推出的，後來在PlayStation 2版本中加入額外內容。在 Wii版中，不僅完整保留這些內容，還結合動作感應控制，帶來更具臨場感的操作體驗，成為當時生存恐怖遊戲的經典之作。

故事發生 2004年，主角里昂·S·肯尼迪（Leon S. Kennedy）是美國政府的特工。距離他在《惡靈古堡2》中倖存的浣熊市事件已經過去六年，此時的里昂接受一項艱鉅任務：前往偏遠的歐洲村莊，拯救被神秘邪教組織綁架的美國總統之女艾雪莉·葛拉漢（Ashley Graham）。到達村莊後，里昂發現當地居民被寄生蟲「Las Plagas」感染，變得異常狂暴，進而成為邪教組織「Los Iluminados」的控制傀儡。隨著深入探索，不僅需要對抗失去人性的村民和邪教信徒，還將面對眾多骇人的生物武器，以及背後的邪教頭目奧斯曼德·賽德勒（Osmund Saddler）。

里昂的旅程充滿懸疑和恐懼，他不僅要解救艾雪莉，還需解開「Las Plagas」的秘密，並找到方法消除感染。在這過程中，遇到神秘女子艾達·王（Ada Wong），她擁有自己的目的和計畫，增加劇情的複雜性與深度。最終，里昂與艾雪莉成功逃脫並摧毀邪教組織，但這段驚心動魄的經歷也揭開該系列未來的故事走向。

充分利用Wii遙控器和Nunchuk控制器的體感功能，改變以往在家用主機上使用傳統手柄操作的方式。使用Wii 遙控器進行準確的瞄準，無需依賴搖桿控制。透過感應遙控器的移動，輕鬆將準星對準敵人，這使得射擊更加精確且直觀。此外，搖晃Nunchuk還能觸發近身攻擊，使得戰鬥更具互動性。大幅提升沉浸感，特別是在面對大量敵人或強大頭目時，能迅速反應並做出動作。

在操作的細節上，保留原作的戰鬥風格，在瞄準時角色會停下腳步，這營造更強的緊張感與危機意識。還包含多種武器與道具管理，透過控制器便捷地打開物品欄、裝備和調整武器，提升戰鬥的靈活度。此外，還加入Quick Time Event（QTE）系統，在特定場景和劇情中需要迅速按下指定按鈕來避開危險或進行反擊，增強劇情的動態性。

關卡設計涵蓋村莊、城堡和軍事基地等多種場景，每個場景都充滿隱藏的危機和謎題。以半開放式的關卡進行，探索場景中的各個細節，包括收集資源、解鎖武器和裝備。村莊部分展現陰森的農村風景，充滿黑暗的氛圍和瘋狂的村民，而城堡則引入大量機關和陷阱，解開謎題、打敗陷阱守衛才能前進。軍事基地則包含高科技設備和更強大的敵人，考驗玩家的戰術策略和射擊能力。此外，還包含額外的內容，比如「艾達篇章」（Separate Ways），從艾達·王的視角重新審視事件的真相，並揭開她與組織的關聯。這額外內容讓人能更全面地了解遊戲世界觀和劇情，也增強重玩價值。

在推出後獲得廣泛好評。玩家和評論家普遍認為Wii的體感操作系統為遊戲增色不少，讓原本就非常出色的可玩性達到新的高度。視覺效果和場景設計在Wii上雖然與最新主機相比略顯過時，但整體畫面仍能表現出令人滿意的細節，尤其是氣氛營造效果依然出色。劇情、角色刻畫和緊張刺激的戰鬥場面獲得高度肯定。

操作系統被認為是對生存恐怖遊戲操控的成功創新，能輕鬆上手並享受到與敵人周旋的刺激感，精確瞄準和流暢操作也提高代入感。因此，《Biohazard 4 Wii Edition》被評為Wii上最具代表性的第三方遊戲之一。評論家特別讚賞卡普空對操作的調整，認為其體感操作並未破壞原作的恐怖氛圍，而是增強玩家的參與度。由於其優異的表現，Wii 版的銷量穩定上升，為卡普空帶來可觀的收益，並進而鞏固該系列在全球市場上的地位。

"Resident Evil 4: Wii Edition" is an enhanced version of the classic survival horror game "Resident Evil 4," developed by Capcom and released for the Nintendo Wii in 2007. The original game debuted on the GameCube in 2005, with additional content later introduced in the PlayStation 2 version. The Wii edition not only retains all the extra content but also incorporates motion-sensing controls, delivering a more immersive gameplay experience, making it one of the most iconic survival horror games of its time.

The story takes place in 2004, following protagonist Leon S. Kennedy, a U.S. government agent. Six years have passed since the Raccoon City incident in "Resident Evil 2," and Leon is now tasked with a dangerous mission: to rescue Ashley Graham, the kidnapped daughter of the U.S. President, from a remote European village. Upon arriving, Leon discovers that the villagers have been infected by a parasitic organism known as "Las Plagas," turning them into aggressive puppets controlled by the mysterious cult "Los Iluminados." As Leon delves deeper, he faces not only hostile villagers and cultists but also terrifying bioweapons and the cult’s leader, Osmund Saddler.

Leon’s journey is fraught with suspense and fear as he races to save Ashley, unravel the secrets of Las Plagas, and find a way to eliminate the infection. Along the way, he encounters the enigmatic Ada Wong, whose personal motives and hidden agenda add complexity and depth to the narrative. Ultimately, Leon and Ashley manage to escape and destroy the cult, but the harrowing ordeal sets the stage for the series’ future developments.

The game leverages the Wii Remote and Nunchuk controllers to introduce motion-sensing features, revolutionizing the traditional console gameplay experience. The Wii Remote allows for precise aiming without relying on joystick control, enabling players to easily point and shoot at enemies by moving the remote. This intuitive system enhances accuracy and immerses players in the action. Additionally, shaking the Nunchuk triggers melee attacks, adding a layer of interactivity to combat. This new control scheme significantly heightens the sense of immersion, particularly during encounters with large enemy hordes or powerful bosses, allowing for quick reflexive actions.

The gameplay retains the original combat mechanics, where the character halts while aiming, amplifying tension and the sense of vulnerability. The game includes a diverse arsenal of weapons and an inventory system that can be easily accessed and managed through the Wii controls. Quick Time Events (QTEs) are also present, requiring players to rapidly press specific buttons during key scenes to evade danger or counterattack, further enhancing the dynamic nature of the gameplay.

Level design spans various environments, including villages, castles, and military bases, each filled with hidden dangers and puzzles. The semi-open level structure encourages thorough exploration, with players scavenging for resources, unlocking weapons, and acquiring gear. The village portion immerses players in a dark, eerie rural setting with hostile villagers, while the castle introduces traps, puzzles, and formidable enemies. The military base segment features advanced technology and more powerful adversaries, demanding strategic thinking and precise shooting.

The game also features additional content such as the "Separate Ways" campaign, providing a new perspective on the events through Ada Wong’s eyes and shedding light on her connection to the organization she serves. This bonus content enriches the game’s lore and increases replayability by offering deeper insight into the overarching storyline.

Upon release, "Resident Evil 4: Wii Edition" received widespread acclaim. Players and critics praised the motion controls for enhancing the already exceptional gameplay, elevating its playability to new heights. While the graphics and visual fidelity on the Wii were not as advanced as on newer consoles, the game’s atmospheric design and detailed environments remained impressive, effectively conveying a sense of dread and tension. The gripping storyline, well-developed characters, and intense combat sequences were highly lauded.

The Wii control scheme was heralded as a groundbreaking innovation for survival horror games, offering intuitive handling that made it easier to engage in the game’s intense battles while maintaining the thrilling sense of danger. The combination of precise aiming and seamless control boosted player immersion significantly. As a result, "Resident Evil 4: Wii Edition" was recognized as one of the most definitive third-party games on the Wii. Critics particularly commended Capcom for the thoughtful control adjustments, noting that the motion-sensing gameplay did not detract from the horror atmosphere but rather enhanced player involvement.

Due to its exceptional performance, the Wii edition achieved strong and consistent sales, generating substantial revenue for Capcom and further solidifying the franchise’s global standing.
