《MILESTONE 射擊遊戲收藏集 闇羽天鴉 Wii》（日文名稱：カラスWii マイルストーンシューティングコレクション）是由日本遊戲公司Milestone Inc.製作並發行的彈幕射擊遊戲合輯，於2008年發行於任天堂Wii平台。是對該公司在街機與Dreamcast平台上發表過的多款射擊遊戲的重製與彙整，特別針對射擊遊戲愛好者及街機懷舊玩家而設計。核心作品為《KAROUS（闇羽天鴉）》，並收錄如《Chaos Field》、《Radirgo Noa Wii》與《Illvelo》等多部風格獨特的射擊遊戲，提供完整的射擊遊戲體驗集。

其中，《KAROUS（カラス）》為最具代表性的遊戲，也是Wii版本主打特色。採橫向捲軸的彈幕射擊遊戲，畫面風格強烈地採用灰黑色調與未來科技感設計，形成獨特的「陰鬱科技美學」。劇情設定在一個反烏托邦未來世界，主角Karous是女性駕駛者，操控著飛行裝備對抗控制社會的強大機械勢力。雖然劇情在遊戲中不是明確主軸，但透過關卡背景與音樂表現出孤獨與抗爭的感覺。

遊戲系統方面，《KAROUS》與其他Milestone作品相似，加入大量自訂與升級要素。機體可以收集經驗球進行升級，並針對武器、劍技與護盾進行強化，透過不同等級的成長來改變彈幕形態與威力。操作部分以Wii遙控器和Nunchuk進行基本移動與射擊，亦可選擇使用經典控制器以模擬街機搖桿操作，忠實呈現原始手感。遊戲節奏快速，敵彈密集但圖像清晰，強調的是閃避技巧與資源運用的策略性。

而整個合集中所包含的遊戲各有風格：
《Chaos Field》強調BOSS連戰與「現實／混沌」雙重世界切換系統，面對多重型態的強敵並切換攻防節奏；
《Radirgo Noa Wii》則採用漫畫風格的彩色畫面與輕鬆音樂，融合一般射擊與近距離武器的組合玩法，調性明亮但挑戰度不低；
《Illvelo》則是融合迷幻色彩與瘋狂關卡設計的另類射擊作品，充滿創意與混亂美學。

整體視覺方面，這些遊戲雖非以寫實畫質取勝，但皆擁有極強的視覺辨識度與風格統一性。Milestone一向走非主流藝術路線，無論是黑白輪廓風、漫畫化角色設計、或是未來電子風的圖像構成，都讓這些作品在射擊遊戲市場中保持獨樹一幟的地位。音樂部分同樣值得一提，《KAROUS》與《Radirgo Noa Wii 》的配樂風格皆為電子音樂或實驗性音軌，極具節奏感與未來感，與畫面節奏形成完美呼應。

市場評價方面，在主流媒體評價中表現平平，但在小眾射擊遊戲社群中頗受好評。許多玩家認為是對Milestone過去作品的最佳彙整，並感謝Wii版本提供家庭平台上的街機彈幕體驗。不過也有批評指出Wii版的畫面解析度未經大幅強化，與原版相比提升有限；且體感操作支援較弱，大多仍建議使用傳統手把進行遊玩。《Fami通》給予27/40的評價，肯定遊戲性與收藏價值，但指出其視覺表現與操作介面偏向硬核玩家，對新手或一般Wii用戶來說門檻略高。

總結來說，這是專為垂直射擊與彈幕遊戲愛好者設計的收藏型作品。雖然技術層面未達現代主機的標準，但其獨特藝術風格與系統深度仍足以吸引核心玩家長時間鑽研。對於喜愛經典街機風格、尋求挑戰與風格化彈幕美學的玩家而言，值得珍藏與回味的射擊遊戲合輯。

"Milestone Shooting Collection: Karous Wii" (Japanese title: カラスWii マイルストーンシューティングコレクション) is a bullet-hell shoot-’em-up compilation developed and published by Japanese studio Milestone Inc., released for the Nintendo Wii in 2008. This title serves as a remastered collection of several arcade and Dreamcast-era shooters produced by the company, curated especially for fans of the genre and arcade nostalgia. The centerpiece of the collection is Karous, while other titles included are Chaos Field, Radirgo Noa Wii , and Illvelo—each offering a distinctive take on the shooting genre.

At the heart of the collection is Karous (カラス), the flagship title and the most thematically defining entry. A horizontally scrolling bullet-hell shooter, it’s characterized by its stark monochromatic visuals and futuristic, dystopian aesthetic—a style often described as “melancholic techno-beauty.” Set in a bleak future ruled by authoritarian machines, the story follows Karous, a female pilot fighting against an oppressive mechanical regime using advanced aerial weaponry. Although the narrative takes a back seat, the game conveys a strong atmosphere of solitude and resistance through its environmental design and haunting musical score.

Karous and other Milestone titles in the collection share a gameplay philosophy focused on customization and progression. Players collect experience orbs during combat to level up their ship, with enhancements available for weapons, melee sword techniques, and shield systems. These upgrades not only increase power but also alter the bullet patterns, encouraging strategic planning and skillful execution. Controls support both the Wii Remote/Nunchuk combo and the Classic Controller, allowing for arcade-style play that preserves the original tactile experience. The game features fast-paced action, dense bullet patterns, and clear visuals that reward precise dodging and resourceful play.

Each game in the collection brings a distinct style:

• Chaos Field emphasizes relentless boss battles and a unique dual-world mechanic, where players can shift between “Reality” and “Chaos” modes to adapt to enemy attack patterns and alter their strategies mid-fight.
• Radirgo Noa Wii adopts a bright, comic book aesthetic paired with upbeat music. It mixes traditional shooting with melee combat, allowing close-range attacks, which adds a fresh dynamic. While visually lighthearted, it still offers a formidable challenge.
• Illvelo takes a more abstract, psychedelic approach, combining wild stage designs and chaotic visual elements in a surreal, almost nonsensical bullet-hell experience. It’s creative and visually overwhelming, catering to players who enjoy unorthodox design.

While the games don’t aim for photorealism, each features a strong and cohesive visual identity. Milestone’s art direction leans toward the non-mainstream: be it black-and-white silhouettes, comic-inspired character designs, or futuristic digital motifs, the titles maintain a distinctive presence within the genre. The soundtrack is another highlight—Karous and , Radirgo Noa Wii in particular, feature electronic and experimental tracks that match the rhythm and atmosphere of gameplay, creating a tightly woven audiovisual experience.

Critically, the collection received mixed reviews from mainstream outlets but found appreciation within niche shooter communities. Many fans saw it as the best way to experience Milestone’s catalog, and praised the Wii version for bringing arcade-quality shoot-’em-ups into the home environment. However, criticisms included the lack of significant graphical upgrades from the originals and weak implementation of motion controls, with most recommending the use of traditional gamepads. Famitsu awarded it 27 out of 40, praising its gameplay and collector value, while noting that its hardcore-focused visual and interface design may pose a steep learning curve for casual Wii users.

In summary, Milestone Shooting Collection: Karous Wii is a compilation tailored for vertical shooter and bullet-hell enthusiasts. Though technically dated by modern standards, its artistic uniqueness and gameplay depth make it a compelling experience for dedicated fans. For those who appreciate classic arcade vibes, stylized bullet patterns, and challenging mechanics, this collection stands as a memorable and worthy addition to any Wii library.
