1996年於Neo Geo街機基板（MVS）登場，並在之後移植至AES與CD家用主機的《神凰拳》（Operation Ragnagard），是由Saurus開發、SNK發行的一款2D對戰格鬥遊戲。在90年代中期格鬥遊戲百家爭鳴的時代，並未選擇走主流的寫實或動漫風格，而是以極具實驗性的預渲染點陣圖技術與神話題材作為核心，打造出一款在視覺與氛圍上都極具衝擊力的異色作品，也因此在Neo Geo龐大的作品群中顯得格外孤高而前衛。

在基本資料與整體表現方面，最引人注目的莫過於其大膽採用「偽3D預渲染點陣圖」的技術路線。開發團隊先以3D建模方式塑造角色，再轉換為2D點陣圖呈現，讓人物帶有強烈的立體感與厚重的金屬質地，並透過光影變化強化肌肉線條與神性威壓。這種表現方式與當時流行的純手繪風格形成強烈對比，雖然評價兩極，但成功塑造出一種壓迫感十足的「神與神對決」氛圍。場景設計同樣走宏大路線，搭配雷電、火焰與能量爆發等誇張特效，使整體畫面充滿毀滅性的張力。音樂則以交響樂風格為主軸，結合沉重的打擊音效與低鳴聲響，進一步烘托出末世神話的史詩格局。

在劇情設定上，描繪的是一場跨越各大文明的神話大戰。當至高神的力量逐漸衰退，象徵世界終結與重生的「諸神黃昏」預言開始應驗，各地的神祇與傳說英雄紛紛覺醒並聚集於此。來自不同神話體系的存在，包括掌控雷霆的戰神、象徵破壞與重生的神明，以及代表光與闇的超越存在，都為了爭奪新的神之王座而投入戰鬥。這場名為「神凰拳」的競技不再只是單純的比武，而是一場攸關世界秩序重塑的生存之戰。每一位角色都背負著自身的信仰與使命，在混沌之中尋求最終的支配權與存在價值。

在操作與系統設計方面，展現出與傳統SNK格鬥遊戲截然不同的手感與節奏。遊戲極度強調空中戰鬥的比重，角色不僅擁有多段跳躍與滯空能力，還能在空中進行衝刺與軌道變換，使戰場從地面大幅延伸至空域，形成多層次的立體攻防。這種設計讓玩家可以進行連續的空中追擊與華麗連段，帶來近似「空戰格鬥」的獨特體驗。同時，遊戲中的能量蓄積系統允許玩家主動累積力量，並依據能量等級釋放不同層級的神術與必殺技。當能量達到頂點時，角色可施展極具魄力的神級奧義，畫面往往伴隨著全面性的光影爆發或吞噬一切的黑暗效果，呈現出壓倒性的破壞力。此外，由於角色採用預渲染圖像，其動作節奏與碰撞判定也顯得格外厚重，每一次攻擊都伴隨強烈的震動與視覺回饋，使整體打擊感顯得極具份量。

在市場評價方面，被普遍視為一款風格極端鮮明的作品。評論界對其視覺表現與神話題材給予高度肯定，認為它在Neo Geo平台上開創一種前所未見的美術方向，成功將不同文化的神祇融合為一場壯觀的「神話大亂鬥」。然而，其預渲染角色所帶來的動作銜接感與操作節奏，也讓部分玩家感到不易上手，尤其是習慣傳統流暢點陣動畫的玩家，往往需要時間適應這種偏向厚重且略帶延遲感的操作風格。

即便如此，《神凰拳》在後世的評價依然穩固，並逐漸被視為 Neo Geo 時期極具辨識度的「實驗性傑作」。雖然它的知名度不及同期的主流大作，但其獨特的視覺語言與誇張的神力表現，使其在復古玩家與收藏市場中佔有一席之地。它不僅象徵著 90 年代遊戲技術探索的一次大膽嘗試，也是一部讓玩家能親身體驗「弒神之戰」壯闊魅力的另類經典。

Released in 1996 for the Neo Geo arcade system (MVS) and later ported to the AES and CD home consoles, Operation Ragnagard (known in Japan as Shinkouken) is a 2D fighting game developed by Saurus and published by SNK. Emerging during the fiercely competitive fighting game boom of the mid-1990s, the title stood apart by rejecting mainstream visual styles in favor of an experimental approach built around pre-rendered sprites and mythological themes. This bold direction gave it a striking identity, making it one of the most unconventional and avant-garde entries in the Neo Geo library.

In terms of overall presentation, Operation Ragnagard is best known for its use of “pseudo-3D” pre-rendered sprite technology. Characters were first modeled in 3D and then converted into 2D sprites, resulting in a distinctive visual style defined by heavy shading, metallic textures, and pronounced musculature. This approach sharply contrasted with the hand-drawn pixel art that dominated the era. While reception to the style was divided, it undeniably created a powerful sense of scale and intensity, reinforcing the theme of divine combat. The stages are equally grand, filled with dramatic effects such as lightning, flames, and explosive energy bursts, all contributing to a sense of overwhelming destruction. The soundtrack leans heavily into orchestral compositions, supported by deep percussion and resonant tones, amplifying the game’s epic, mythological atmosphere.

The story unfolds in a mythological realm where gods from various cultures coexist. As the power of the supreme deity begins to wane, the prophecy of an impending apocalypse—akin to Ragnarok—starts to materialize. In response, divine beings and legendary heroes from across different mythologies awaken and converge. These include thunder gods, deities of destruction and rebirth, and celestial beings representing light and darkness. The “Operation Ragnagard” tournament is not merely a contest of strength, but a battle to determine who will ascend as the new supreme ruler and reshape the world’s order. Each character enters the conflict driven by their own beliefs and purpose, seeking dominance in a chaotic struggle for transcendence.

From a gameplay perspective, the system diverges significantly from traditional SNK fighters, offering a unique sense of weight and spatial dynamics. A key feature is its strong emphasis on aerial combat. Characters possess multi-layered jumps, extended air time, and the ability to dash or alter their trajectory mid-air, effectively expanding the battlefield into vertical space. This allows for elaborate aerial combos and pursuit strategies, giving the game a distinctive “air battle” feel. In addition, the power gauge system enables players to manually charge energy, which can then be unleashed in varying levels of special moves and super attacks. At maximum charge, characters can perform devastating god-tier techniques, often accompanied by dramatic full-screen visual effects such as blinding light or engulfing darkness. Due to the pre-rendered animation style, movements carry a heavier, more deliberate rhythm, and each hit is reinforced by strong visual feedback and screen-shaking impact, emphasizing the sheer force behind every attack.

Critically, Operation Ragnagard is often regarded as a highly distinctive and polarizing title. Reviewers praised its ambitious visual experimentation and its bold fusion of mythologies, recognizing it as a unique “mythological crossover” within the Neo Geo catalog. However, the unconventional animation and heavier gameplay feel posed a challenge for players accustomed to the fluidity of traditional 2D fighters, requiring time and adjustment to fully appreciate its mechanics.

Despite its mixed reception at launch, the game has since earned a reputation as an experimental cult classic. While it never achieved the widespread popularity of SNK’s flagship franchises, its unique aesthetic and exaggerated portrayal of divine power have secured it a dedicated following among retro enthusiasts and collectors. Today, it stands as both a testament to the technological experimentation of the 1990s and a distinctive experience for players seeking a grand, godlike battle unlike anything else on the Neo Geo platform.
