《快打旋風II′－冠軍版－》（Street Fighter II′: Champion Edition，日語：ストリートファイターIIダッシュ -Champion Edition-）是由卡普空（Capcom）於1992年推出的經典格鬥遊戲，最初在大型電玩平台上發行，之後陸續移植至PC Engine、Genesis/Mega Drive、X68000及CPS Changer等多個平台。作為《快打旋風II》的首個重大改版作品，在前作的基礎上加入多項重要更新，使遊戲更加平衡且玩法更為多元。

在劇情與角色設計方面，首次將前作中作為電腦對手的四位「四大天王」（Balrog、Vega、Sagat、M. Bison）開放為可操作角色，不僅可以用他們挑戰CPU，也可以與其他玩家對戰。這些四大天王雖然在遊戲中的能力比原本僅限CPU操作時有所削弱，但仍然比原始八位角色強大，為比賽增加更多策略性和挑戰性。原先八位角色的技術則經過平衡性調整，例如Ryu與Ken的招式差異更加明顯，使得角色間的對戰更加公平且具競技性。

遊戲操作方面，引入鏡像對戰的功能，即可以與同一角色進行對戰，增強競技性與趣味性。在選擇鏡像對戰時，遊戲會自動為其中一名角色更換顏色以便區分，例如春麗的紅色服裝或布蘭卡的藍色皮膚，並在生命條下方顯示藍色名字標籤。這也使單人模式中玩家將面對所有12位角色，並增加一場鏡像對戰，使遊戲挑戰性和重玩價值顯著提升。

在視覺與音效方面，對角色立繪、背景色彩及部分角色的結局畫面進行更新，並在工作人員名單與結尾序列中加入新的背景音樂，使整體視覺與聽覺效果更加精緻。此外，可以在選擇角色時自主決定使用標準色或替代色方案，提供更多個性化選擇。

市場評價方面，自推出以來廣受玩家與媒體好評。在Gemesuto評選中，它被評為1992年度最佳遊戲；在Sega Mega Drive平台上的移植版本也獲得正面評價，《Fami通》甚至給予滿分10/10的高分。玩家對其在角色平衡、操作手感及鏡像對戰機制上的改進尤其讚賞，認為這是格鬥遊戲歷史上一個具有里程碑意義的版本，使《快打旋風》系列的競技性與耐玩性都得到顯著提升。

整體而言，《快打旋風II′－冠軍版－》不僅延續原作的快節奏打擊感和鮮明角色魅力，更透過角色可操作性、平衡性調整及視覺音效升級，奠定街機格鬥遊戲的經典地位，成為格鬥遊戲愛好者必玩的經典作品之一。

Street Fighter II′: Champion Edition (Japanese: ストリートファイターIIダッシュ -Champion Edition-) is a classic fighting game developed and published by Capcom in 1992. Originally released for arcade platforms, it was later ported to multiple systems including PC Engine, Genesis/Mega Drive, X68000, and CPS Changer. As the first major update to Street Fighter II, Champion Edition introduced several important enhancements, making the game more balanced, competitive, and versatile.

In terms of characters and gameplay, this edition allowed players to control the four “Grand Masters” (Balrog, Vega, Sagat, and M. Bison), who were previously exclusive CPU opponents in the original World Warrior version. Players could now use these characters against the CPU or in player-versus-player matches. While these Grand Masters were slightly toned down compared to their original CPU versions, they remained stronger than the original eight characters, adding a new layer of strategy and challenge. The original eight fighters also received refined movesets and adjustments to balance competitive play, with Ryu and Ken’s fighting styles becoming more distinct from each other.

One of the notable gameplay innovations in Champion Edition was the introduction of mirror matches, allowing players to face off against the same character. To differentiate between the two, one character would retain their standard palette while the other would use an alternate color scheme, such as Chun-Li’s red outfit or Blanka’s blue skin, with a blue name tag under their health bar. This feature increased both the challenge and replayability of the game, and in single-player mode, it expanded the experience to include all twelve characters, including a mirror match.

Graphically, the game made minor updates, such as enhanced color palettes for each stage, redrawn character portraits, and revised ending visuals for some fighters. The staff roll sequence also featured new background music, creating a more polished visual and auditory experience. Players could also select either the standard or alternate color scheme for each character during character selection, allowing for more personalization.

Street Fighter II′: Champion Edition received widespread critical acclaim. It was awarded the 1992 Game of the Year by Gemesuto and garnered positive reviews for its Sega Mega Drive port, with FamiCom giving it a perfect 10/10 score. Critics and players particularly praised the game’s improved character balance, refined controls, and the new mirror match system, noting that it enhanced both competitiveness and replay value.

Overall, Champion Edition not only preserved the fast-paced action and distinctive character appeal of the original Street Fighter II, but also introduced meaningful improvements in character selection, gameplay balance, and audiovisual presentation. These updates cemented its status as a landmark entry in the fighting game genre, making it a must-play classic for fans and a defining chapter in the Street Fighter series.
