《瑪利歐網球 狂熱》（Mario Tennis Fever）是《瑪利歐網球》系列的第九部作品，也是首款於Nintendo Switch 2登場的瑪利歐體育類遊戲。任天堂將其安排於2026 年2月12日發售，正好呼應《超級瑪利歐兄弟》系列40週年紀念，因此自消息公開以來便備受矚目。

在操作與系統設計上延續《瑪利歐網球 Ace》的基礎框架，但加入更多攻防選項。除能使用上旋球、削球、高吊球等基本球種之外，還新增滑步追球與飛身擊球兩項防守動作，並且強化透過左右角度、前後移動來變換比賽節奏的攻擊方式，讓整體戰術性更為鮮明。比賽中最具突破性的系統莫過於「狂熱球拍」（Fever Racket）。透過比賽累積計量表，便能施展專屬於該球拍的「狂熱擊球」（Fever Shot）。每一支狂熱球拍都有不同能力，例如能在場地上製造巨大冰塊的「冰結球拍」、讓對手縮小的「超小蘑菇球拍」、甚至能創造分身的「影子球拍」，合計多達三十種。這些設計為比賽帶來誇張而充滿驚喜的變化，也使得每場對決都有不確定性。

在劇情模式中，首次嘗試風格強烈的冒險故事。故事敘述瑪利歐與其他角色在一座神秘島嶼上遭遇怪物，結果全體都被變成嬰兒，並因此失去原有的網球技巧。必須帶領這些「寶寶」角色重新學習網球技巧，透過一連串對戰擊敗怪物，才能恢復原本的模樣。這種設定既荒誕又熱血，被官方形容成「宛如七龍珠外傳等級的誇張劇情」。此外，本作也是Baby Luigi首度在系列中成為正式登場角色、Baby Wario第一次出現在家用主機遊戲、而Baby Waluigi則是首次現身。劇情模式的設定不僅滿足系列粉絲對角色新鮮感的期待，也擴展網球比賽之外的敘事張力。

除單人劇情，亦收錄多樣化模式。由「閒聊花花」擔任實況主播炒熱賽事氛圍的「錦標賽」模式、挑戰逐層攀登的「任務高塔」、以特殊規則展開混亂對決的「特別遊戲」，以及融入《超級瑪利歐兄弟 驚奇》元素的特別舞台，讓玩家在傳統球場外也能享受到截然不同的體驗。配合Switch 2的Joy-Con進化，還支援「揮動模式」，可以直接揮動控制器模擬網球動作，增添體感樂趣。

角色與對戰內容同樣豐富。提供系列史上最多的38名角色，加上三十種功能各異的狂熱球拍，依照喜好組合出最適合自己的戰術搭配。線上功能方面，能選擇規則自由的「房間對戰」，或挑戰實力排名的「排位賽」，並能自行設定是否允許使用「狂熱球拍」。這讓不同層級的玩家都能找到最適合的對戰方式，從輕鬆娛樂到嚴肅競技皆可滿足。

市場期待度方面，自公開後便引發熱烈討論。除作為Switch 2的首款瑪利歐體育作品自帶話題性外，遊戲中誇張的球拍特效、全面強化的攻防操作，以及首次嘗試劇情冒險的設定，都使得粉絲與媒體普遍抱持高度期待。不少評論認為本作有望在「運動遊戲」與「派對娛樂」之間找到全新平衡，並延續瑪利歐系列的跨世代吸引力。

總體而言，《瑪利歐網球 狂熱》不僅是系列的進化之作，也展現任天堂為Switch 2打造娛樂盛宴的野心。在競技與娛樂、傳統與創新之間取得融合，無論是單人玩家還是多人對戰愛好者，都能在這款遊戲中找到專屬的樂趣。隨著2026年2月發售日的臨近，這款作品勢必將成為任天堂40週年紀念的核心亮點之一。

Mario Tennis Fever is the ninth entry in the long-running Mario Tennis series and the very first Mario sports title to debut on the Nintendo Switch 2. Scheduled for release on February 12, 2026, the game also serves as a centerpiece for the Super Mario Bros. 40th anniversary celebration. Since its announcement, it has generated significant buzz among fans and media alike.

Building on the foundation of Mario Tennis Aces, the game refines and expands its mechanics to deliver deeper tactical play. In addition to classic shots such as topspin, slice, and lob, players can now use defensive moves like quick slides and diving saves. Offense has also been enhanced with greater emphasis on angle control and tempo shifts, allowing for more layered strategies. The biggest innovation, however, comes from the new Fever Racket system. By charging a Fever Gauge during rallies, players can unleash powerful Fever Shots unique to each racket. With thirty distinct Fever Rackets—ranging from the Ice Racket that freezes parts of the court, to the Mini-Mushroom Racket that shrinks opponents, and the Shadow Racket that creates a clone—matches are infused with unpredictability and spectacular effects.

The game also introduces an ambitious story mode with a dramatic, almost over-the-top flair. The plot sees Mario and other characters stranded on a mysterious island where they are transformed into babies by monsters, losing their tennis abilities in the process. Players must retrain these baby versions of the characters, battling enemies in tennis matches to restore them to their original forms. This quirky yet intense premise, described by Nintendo as “Dragon Ball-level exaggerated,” adds narrative depth to the series. It also marks notable character milestones: Baby Luigi makes his first proper series appearance, Baby Wario debuts on a home console, and Baby Waluigi enters the franchise for the very first time.

Beyond the story, Mario Tennis Fever offers a wealth of modes. The Tournament Mode features live commentary by the in-game character Chitchat Flower, while Mission Tower challenges players with ascending stages of escalating difficulty. Special modes with unique rules, as well as courts inspired by Super Mario Bros. Wonder, expand gameplay variety. Thanks to the enhanced capabilities of the Switch 2 Joy-Con controllers, the game also supports a “Swing Mode,” allowing players to physically mimic tennis swings for a motion-controlled experience.

The roster and customization options are richer than ever, boasting the series’ largest lineup with 38 playable characters and 30 unique Fever Rackets. Online play accommodates both casual and competitive audiences, with flexible custom rule sets in Room Matches and skill-based Ranked Battles. Players can also choose whether or not to enable Fever Rackets, ensuring a balance between pure competitive play and chaotic, party-like fun.

From a market perspective, the game has already stirred strong anticipation. As the Switch 2’s first Mario sports title, expectations are high, and fans are especially excited by the combination of over-the-top racket effects, polished mechanics, and a fresh narrative adventure. Critics have suggested that Mario Tennis Fever could strike a new balance between sports gameplay and party entertainment, further cementing Mario’s cross-generational appeal.

Overall, Mario Tennis Fever represents not just an evolution of the series but also a bold showcase of Nintendo’s vision for the Switch 2. Blending competition with entertainment, and tradition with innovation, it promises something for everyone—whether solo players seeking a story-driven challenge or groups looking for lively multiplayer fun. With its February 2026 release fast approaching, it is already shaping up to be one of the cornerstone titles of Nintendo’s 40th anniversary celebrations.
