由 Banpresto 於 1990 年 12 月 29 日在任天堂 Famicom（紅白機）上推出的《英雄挑戰》（Great Battle Cyber / グレイトバトルサイバー），是著名跨界系列 Compati Hero Series 在 8 位元主機上的代表性動作作品之一。最具劃時代意義之處，在於將三大人氣特攝與機器人 IP——機動戰士鋼彈、假面騎士 與 超人力霸王——成功融合於同一個遊戲世界之中，開啟日後長達數十年的跨界傳奇。

在技術表現方面，展現紅白機末期已趨成熟的開發水準。採用當時極受歡迎的「SD（二頭身）」風格，將原本形象嚴肅的鋼彈與巨大的超人力霸王轉化為可愛又不失英氣的小型角色，使不同作品的主角能自然共存於同一畫面中而不顯突兀。關卡設計涵蓋都市、森林、熔岩地帶與外太空等多樣場景，雖然受限於硬體色數，但整體畫面依然細緻且動作流暢。音樂部分更是亮點之一，製作團隊將三大系列的經典主題曲改編為紅白機音源版本，並在角色切換時即時變換旋律，成功喚起玩家強烈的情懷與代入感。

故事背景設定在一個多重宇宙交織的世界。邪惡組織「暗黑軍團」突然發動全面侵略，綁架來自各個時空的英雄並企圖征服宇宙。面對這場前所未有的危機，來自不同世界的守護者決定攜手合作，組成「Great Battle」特遣隊。玩家將操作鋼彈、假面騎士與超人力霸王三大英雄，深入敵方據點，解救被囚禁或洗腦的夥伴，最終挑戰暗黑軍團的首腦。整體劇情雖然採取王道的「營救與反擊」架構，但成功傳達出友情、正義與團結對抗邪惡的核心精神。

在操作系統上，最大的特色是即時角色切換機制。在戰鬥中隨時切換三位主角，根據不同情況靈活應對。鋼彈（F91）擅長遠距離射擊並具備良好的滯空能力，假面騎士Black RX 則以快速的近身格鬥與強力攻擊見長，而 超人力霸王太郎 則擁有強大的投擲技與能量光線。這種依據敵人類型與地形選擇角色的操作方式，讓遊戲在動作之外增添了策略層次。

此外，還融入輕度的角色成長要素。在擊敗敵人後可以累積經驗值並提升等級，進一步強化體力與攻擊力，甚至解鎖新的必殺技。戰鬥回饋相當紮實，特別是在施放必殺技時所呈現的特效，帶來強烈的爽快感。同時，部分關卡亦包含探索與解謎元素，需要善用不同角色的能力來開啟隱藏路徑或突破機關，使三位英雄各自的特色都能發揮作用。

在市場評價方面，普遍獲得高度肯定。評論界認為，本作不僅成功整合多個知名 IP，更在遊戲性上展現出誠意與創新，是早期授權改編遊戲中難得一見的佳作。儘管部分資深玩家認為整體難度較為親民、流程略短，但其所帶來的視覺衝擊與情懷價值依然無可取代。如今，被視為 Compati Hero Series 的奠基之作，並為後續在超級任天堂平台上更加成熟的《Great Battle》系列鋪平道路，成為許多老玩家心中不可動搖的經典跨界神作。

Released by Banpresto on December 29, 1990 for the Nintendo Famicom, Great Battle Cyber (グレイトバトルサイバー) stands as one of the defining action titles of the early Compati Hero Series on 8-bit hardware. The game broke boundaries by bringing together three of Japan’s most iconic hero franchises—Mobile Suit Gundam, Kamen Rider, and Ultraman—into a single crossover experience, laying the foundation for a legendary multi-decade collaboration series.

In terms of presentation, the game showcases the technical maturity of late-era Famicom development. It adopts the highly popular “SD” (Super Deformed) art style, transforming traditionally serious characters like Gundam and Ultraman into charming, super-deformed heroes without losing their heroic appeal. The stages span a variety of environments, including cities, forests, lava zones, and outer space. Despite the hardware’s color limitations, the visuals remain detailed and fluid. Musically, the game delivers a nostalgic highlight by adapting iconic theme songs from all three franchises into chiptune form. When players switch characters, the background music changes accordingly, creating an immediate emotional connection for fans.

The story takes place in a fantastical Earth where multiple universes intersect. A sinister organization known as the Dark Empire launches a large-scale invasion, kidnapping heroes from different worlds and attempting to conquer the universe. In response, legendary defenders from across space and time—Gundam, Kamen Rider, and Ultraman—set aside their differences to form the “Great Battle” task force. The narrative follows a classic rescue-and-counterattack structure, as players infiltrate enemy bases, save captured allies such as RX-78-2 Gundam and Kamen Rider Ichigo, and ultimately confront the mastermind behind the invasion. It is a straightforward yet powerful tale centered on friendship, justice, and unity.

Gameplay revolves around a dynamic character-switching system that adds both action and strategy. Players can switch between three heroes at any time by pressing a command combination. Each character has distinct strengths: Gundam (F91) excels at ranged combat and aerial control, Kamen Rider Black RX specializes in fast melee attacks with strong hit detection, and Ultraman Taro offers powerful throws and energy-based beam attacks. Choosing the right hero depending on enemy types and situations becomes essential, adding depth beyond standard action gameplay.

The game also incorporates light RPG elements. Defeating enemies grants experience points, allowing characters to level up, increasing their health and attack power while unlocking special moves. The feedback is especially satisfying during the execution of these abilities, enhanced by flashy visual effects. Additionally, certain stages include exploration and puzzle-solving elements, requiring players to use each hero’s unique abilities to uncover hidden paths or activate mechanisms, ensuring balanced utility among all characters.

Upon release, Great Battle Cyber received strong praise for its ambitious crossover concept, innovative mechanics, and solid gameplay design. Critics highlighted Banpresto’s success in blending three vastly different intellectual properties into a cohesive and enjoyable experience—something rarely achieved in licensed games of that era. While some hardcore players found the difficulty relatively moderate and the overall length somewhat short, the game’s charm, visual appeal, and nostalgic value more than compensated. It is widely regarded as the cornerstone of the Compati Hero Series, paving the way for even more refined sequels on later platforms like the Super Famicom, and remains a beloved crossover classic among retro gaming enthusiasts.
