《終極快打旋風2 最後挑戰者》（英文：Ultra Street Fighter II: The Final Challengers，日文：ウルトラストリートファイターII ザ・ファイナルチャレンジャーズ）是由CAPCOM製作並發行的格鬥遊戲，於2017年作為Nintendo Switch的首發期作品之一推出。經典1991年名作《Street Fighter II》的再強化版本，重新包裝為現代畫面並追加新模式與角色，是向原作致敬的同時，也試圖讓新世代玩家能以嶄新方式體驗這款劃時代的格鬥神作。

劇情背景與主軸仍維持《Street Fighter II》的世界觀，並無明確主線劇情，而是以每位角色的個別故事與結局構成。故事圍繞著來自世界各地的格鬥家們參加全球格鬥大賽的經過與目的，像是追尋自我極限的隆（Ryu）、為父報仇的春麗（Chun-Li）、追求力量的維加（M. Bison）等，透過彼此對戰推動個人劇情，最終達到角色個人的結局。此版本新增兩名角色：邪惡隆（Evil Ryu）與暴怒肯（Violent Ken），兩者都屬於黑化型態，分別體現角色內心的破壞性面向，帶來更多劇情與戰鬥層次。

操作保留傳統六鍵式輸入系統，包括三段強度的拳與腳技。角色可進行跳躍、蹲下、普通攻擊與特殊技能輸入，並透過指令輸入如「波動拳」、「昇龍拳」、「旋風腳」等經典技能施放。在Switch版本中，使用Joy-Con手把進行傳統按鈕輸入，也可以在“Way of the Hado”（波動之道）模式中，透過體感操作來模擬施放隆的技能，像使用Wii般體驗揮拳與波動拳的樂趣。該模式為第一人稱視角動作模式，透過Joy-Con做出各種動作來擊退敵人，雖非主線玩法，但作為附加模式增添趣味性與互動感。

畫面上，提供兩種圖像風格：一種是忠於原作的像素復古畫面，另一種則是由UDON Entertainment重新繪製的高解析2D美術風格，讓玩家可自由選擇懷舊或現代風格的視覺體驗。配樂與音效也可切換經典與重製版，提升自訂性與懷舊感。

市場評價方面，獲得褒貶不一的反應。許多老玩家認為這款作品成功重現經典2D格鬥的精髓，操作手感紮實、節奏明快、角色平衡度優秀，尤其在格鬥遊戲相對稀缺的Switch平台上，提供對完整且可攜式的格鬥體驗。角色陣容完整，共19名角色，加上畫面切換、音樂選擇與多人對戰模式，讓其具有收藏價值與重玩性。

然而，批評聲音主要集中在內容份量與售價之間的落差。部分玩家認為除畫面重製與新角色之外，遊戲機制與整體架構與90年代版本變化不大，對於熟悉此系列的玩家來說創新性不足。加上遊戲售價偏高，使一些玩家認為性價比不夠。此外，“波動之道”模式雖具創意，但操作精度與體感反應不如預期，較易淪為短期噱頭。

總體而言，《終極快打旋風2 最後挑戰者》是以懷舊與傳承為主軸打造的格鬥遊戲作品，雖然在內容創新與深度上未必能與現代格鬥大作如《Street Fighter V》或《Guilty Gear Strive》相提並論，但對於喜愛《快打旋風II》原作的老玩家，或希望在Switch上輕鬆遊玩2D對戰遊戲的新手來說，這仍是值得一試的經典復刻。CAPCOM透過這部作品證明傳統格鬥的魅力依舊歷久彌新，只要操作紮實、畫面精緻、節奏明快，就能跨越時代與世代的隔閡。

Ultra Street Fighter II: The Final Challengers (Japanese title: ウルトラストリートファイターII ザ・ファイナルチャレンジャーズ) is a fighting game developed and published by CAPCOM, released in 2017 as one of the launch window titles for the Nintendo Switch. It is a revitalized and enhanced version of the legendary 1991 classic Street Fighter II, reimagined with modern visuals, additional modes, and new characters. This title serves both as a respectful tribute to the original and as a fresh entry point for new players to experience one of the most iconic fighting games of all time in a contemporary format.

The game retains the world and spirit of Street Fighter II, without a central narrative thread. Instead, it features individual backstories and unique endings for each fighter. The storyline centers around a global martial arts tournament in which fighters from around the world participate for various reasons: Ryu seeks to test the limits of his strength, Chun-Li fights to avenge her father, and M. Bison pursues power and domination. Each encounter between characters contributes to their personal journeys and leads to a distinct conclusion. This version introduces two new characters: Evil Ryu and Violent Ken, both representing darker, corrupted versions of their original selves, adding new layers of narrative and gameplay dynamics.

In terms of controls, the game preserves the traditional six-button input layout, featuring three strengths each of punches and kicks. Characters can perform standard movements such as jumping, crouching, and basic attacks, along with command-based special moves like the iconic Hadoken, Shoryuken, and Tatsumaki Senpukyaku. On the Switch, players can use the Joy-Con controllers for classic button-based inputs, but there’s also a unique mode called “Way of the Hado”, where players use motion controls to simulate Ryu’s moves in a first-person perspective. This mode provides an arcade-like experience reminiscent of the Wii era, allowing players to physically mimic punches and energy blasts. While not part of the core game, it adds an interactive and fun bonus feature.

Visually, the game offers two distinct graphical styles: one is the original pixelated retro look, and the other is a newly redrawn high-resolution 2D art style created by UDON Entertainment. This allows players to switch between nostalgic visuals or modern aesthetics according to their preference. Similarly, the soundtrack and sound effects can be toggled between the classic and remastered versions, enhancing both customization and retro appeal.

Reception of the game was mixed. Many longtime fans appreciated its faithful recreation of the 2D fighting experience, highlighting the tight controls, fast-paced action, and well-balanced roster. On the Switch—a platform with relatively few traditional fighters—it stood out by offering a fully portable and accessible 2D fighting game. With a total of 19 playable characters, multiple visual and audio options, and robust local and online multiplayer, the game was praised for its replay value and collectibility.

However, criticism mainly focused on the perceived gap between content and price. Some players felt that aside from the visual upgrades and two new characters, the core mechanics and structure remained largely unchanged from the 1990s, offering little innovation for veterans of the series. The relatively high price point also led to complaints about value for money. Additionally, while the “Way of the Hado” mode was seen as creative, it was criticized for lacking precision and depth, making it feel more like a novelty than a lasting feature.

In conclusion, Ultra Street Fighter II: The Final Challengers is a fighting game driven by nostalgia and legacy. While it may not rival the depth or innovation of modern titles like Street Fighter V or Guilty Gear Strive, it delivers a solid and visually refined experience that appeals to fans of the original Street Fighter II and newcomers seeking a classic 2D fighter on the Switch. Through this release, CAPCOM demonstrates that the essence of traditional fighting games—tight mechanics, striking visuals, and rhythmic pacing—remains timeless and capable of bridging generations.
