《星之卡比 新星同盟》（日語：星のカービィ スターアライズ，英文：Kirby: Star Allies）是由HAL研究所開發，任天堂於2018年3月在Nintendo Switch平台發行的橫向卷軸動作遊戲。為《星之卡比》系列的主要作品之一，延續系列一貫的可愛畫風與輕鬆節奏，並在操作與玩法設計上引入「同盟系統」，讓卡比能夠招募敵人成為夥伴，共同戰鬥與解謎，強化系列傳統的吸收能力機制，成為Switch上廣受歡迎的家庭合作遊戲之一。

劇情方面，以夢幻世界「夢之泉」為舞台，開場由宇宙深處某個神秘黑暗勢力釋放出詭異的黑心碎片，這些碎片落入夢之泉世界，引發大地異變，也讓原本溫和的角色變得暴躁。卡比在受到碎片影響後意外獲得一種全新的「同盟之力」，能將原本的敵人轉化為隊友，展開旅程阻止黑暗勢力擴散。最終的敵人是神秘的邪神「虛無（Void Termina）」，卡比與他的新盟友們需要穿越各式各樣的關卡，合作戰勝不斷強化的敵軍勢力，恢復世界的和平。

玩法與操作方面，承襲卡比系列的核心系統：卡比吸入敵人並獲得其能力，共有28種如火焰、冰凍、電氣、劍術等。新加入的「投擲愛心」機制是遊戲最大特色，按下特定按鍵將敵人變為同伴，最多可以同時帶領三名AI或玩家控制的角色一同行動。這些同伴不僅能進行攻擊，也能與卡比的能力產生聯動效果，例如將劍附加火焰變為「火焰劍」，或讓冰能力配合石頭變成「滑冰攻擊」等，這種能力組合是解謎與通關的核心。

在單人遊玩時，同伴由電腦控制，AI表現足夠應對大多數場面；而多人遊玩則允許最多四名玩家在同一台Switch上本地合作進行冒險，帶來熱鬧的遊戲體驗。整體操作相當直覺，適合全年齡層。除了主線劇情模式外，遊戲也提供數種挑戰與小遊戲模式，例如「真・最終頭目戰」和「夢之盟友模式」，後者能讓玩家操作過去系列中登場的經典角色如瑪古洛亞、塔朗薩、帝帝帝大王等，提供更多變化與樂趣。

在市場評價方面，發售初期雖受到部分玩家批評其難度偏低與遊戲流程過於簡短，但隨著任天堂陸續釋出多波免費更新，新增眾多可用角色、模式與挑戰內容，使得整體遊戲內容大幅豐富，逐漸扭轉口碑。整體銷量表現亮眼，截至2023年已突破400萬套，是卡比系列歷代銷售表現最佳的作品之一。畫面方面，運用Switch主機效能展現高解析度卡通渲染風格，色彩繽紛且特效流暢，音效與配樂延續系列明快可愛的風格，並重新演繹多首經典旋律，深得粉絲喜愛。

總體而言，《星之卡比 新星同盟》是適合與家人或朋友一同享受的合作型平台動作遊戲，不僅延續卡比系列的傳統魅力，更透過同盟系統賦予新鮮變化，讓戰鬥與解謎都更加豐富。對於喜愛輕鬆遊戲節奏與合作樂趣的玩家來說，是親切且充滿童趣的Switch佳作，也為長壽的卡比系列寫下一段可愛又刺激的新篇章。

Kirby: Star Allies (Japanese: 星のカービィ スターアライズ) is a side-scrolling action game developed by HAL Laboratory and published by Nintendo for the Nintendo Switch in March 2018. As a main installment in the Kirby series, it carries on the franchise’s trademark charming art style and light-hearted pace while introducing the innovative “Friend System.” This new mechanic allows Kirby to recruit former enemies as allies to battle alongside him and solve puzzles, enhancing the traditional copy ability formula and making it one of the most beloved family-friendly co-op games on the Switch.

The story takes place in the fantastical world of Dream Land, where a mysterious dark force from deep space unleashes sinister black heart fragments that rain down upon the land. These fragments disrupt the natural order, turning even peaceful characters aggressive. After being affected by one such fragment, Kirby awakens with a new power: the ability to befriend enemies by throwing hearts at them. Embarking on a journey to stop the spread of this dark energy, Kirby must gather allies and traverse diverse levels filled with enemies and traps. The ultimate antagonist is a godlike entity named Void Termina, and the climax sees Kirby and his newfound friends battling through waves of ever-strengthening foes in a quest to restore peace to the world.

In terms of gameplay, Kirby: Star Allies retains the core mechanic the series is known for—Kirby inhales enemies and gains their abilities. There are 28 unique powers in the game, including fire, ice, electricity, swordplay, and more. The standout new feature is the “Heart Throw” mechanic, where pressing a specific button allows Kirby to convert enemies into teammates. Up to three AI- or player-controlled allies can join Kirby, creating a four-character team. These friends not only assist in combat but also enable ability combinations, such as turning a sword into a flaming sword or merging ice with stone to perform a sliding attack. These combinations are key to both puzzle-solving and progressing through stages.

In single-player mode, the AI handles ally characters competently, making it easy to enjoy the game solo. In multiplayer, up to four players can team up on the same Switch console, creating a festive and cooperative experience. The controls are intuitive and accessible, making the game suitable for players of all ages. Beyond the main story mode, Star Allies also includes additional challenge and mini-game content, such as “The Ultimate Choice” boss rush mode and “Guest Star Mode,” which lets players control iconic characters from past entries like Magolor, Taranza, and King Dedede, offering greater replay value and variety.

At launch, the game received some criticism for its relatively low difficulty and short runtime. However, Nintendo gradually released multiple free updates that added a wealth of new content, including additional playable characters and gameplay modes, significantly enhancing the overall experience. Over time, this led to improved reception from players and critics alike. The game went on to become one of the best-selling titles in the Kirby franchise, surpassing 4 million units sold by 2023.

Visually, Star Allies utilizes the Nintendo Switch’s capabilities to deliver crisp, colorful cartoon-style graphics with smooth animations and vibrant effects. The sound design and music maintain the series’ cheerful tone, and several beloved classic tracks were rearranged, delighting long-time fans.

In conclusion, Kirby: Star Allies is a cooperative platforming game perfect for families and friends to enjoy together. While preserving the traditional charm of the Kirby series, it brings a fresh twist through the Friend System, enriching both combat and puzzle mechanics. For players who enjoy relaxed pacing and collaborative gameplay, it’s a delightful and whimsical experience—and a standout installment that adds a new, exciting chapter to the legacy of the Kirby series.
