《洛克人 ZERO / ZX 傳奇合輯》（日文名：ロックマン ゼロ&ゼクス ダブルヒーローコレクション，英文名稱為Mega Man Zero/ZX Legacy Collection）是由 CAPCOM推出的懷舊型重製作品，於 2020年登陸 Nintendo Switch等多平台。集合原本分散於Game Boy Advance與Nintendo DS上的六款作品：包含《洛克人ZERO》1至4代，以及《洛克人ZX》和《ZX Advent》兩部作品。對於系列的老玩家來說，這是經典重現的珍貴合集；對新玩家而言，則是深入洛克人世界支線時代的重要入門之作。

劇情建立於《洛克人X》系列之後的世界觀，也就是未來的機械生命體時代。《ZERO》系列圍繞著主角「Zero」展開，他原本是《洛克人X》中的重要角色，在沉睡百年後於混亂的未來被一位少女科學家「雪兒」喚醒，加入抵抗軍，對抗由X化身或其意志衍生而來的壓制體制「Neo Arcadia」。這四部曲的故事線黑暗、沉重，主題直指人類與機械生命體的共存矛盾與倫理衝突。

而在《ZERO》結束之後，《ZX》接續個世界觀。在《ZX》中，主角不再是固定角色，而是新的年輕人（Van或Aile），他們透過與傳說中的「生體金屬」（由X與Zero的意志構成的AI武裝）融合來戰鬥，踏上尋找自我、對抗控制與混亂的道路。此系列更加強調個體選擇與成長，並引入更開放的地圖與非線性的任務結構，讓探索元素更加濃厚。續作《ZX Advent》則延續這樣的系統，加入更多轉換形態與戰鬥自由度。

在操作體驗上，對原作的核心手感幾乎沒有改動，依舊保留極富挑戰性的橫向捲軸動作風格。Zero的快速斬擊、牆跳與衝刺技巧，ZX系列的形態轉換與多方向射擊，在Switch的控制器上皆能順暢呈現。CAPCOM也針對現代玩家的習慣進行優化，例如新增「輔助模式」，讓新手可以在遊戲中受到較少傷害，並在地圖中設置更多「存檔點」，使流程變得友善許多。此外，《ZX》和《ZX Advent》原為DS雙螢幕遊戲，本合集透過重製畫面配置，讓玩家能以不同的模擬方式重現當年的雙畫面感，這點在移植層面上表現相當用心。

在視覺呈現方面，選擇保留原始像素風格，或使用柔化處理的濾鏡，使畫面更適合現代高解析度螢幕觀看。不論是哪種風格，人物設計與背景表現仍保有當年濃厚的未來科幻風格，尤其ZERO系列的戰鬥動畫與BOSS設計仍然出色。

推出後，在全球市場獲得廣泛好評。許多遊戲媒體與玩家認為這是CAPCOM對舊作最誠懇的重製之一，不僅保留原味，還加入了\許多便利功能。經典樂曲重新收錄、原畫與插畫的「畫廊模式」、專為此作新增的「Z Chaser」挑戰模式，都讓這款合輯擁有不止是重溫回憶的價值，更成為耐玩性極高的獨立作品。

雖然少數評價指出《ZX》系列中的地圖導引不夠明確，容易迷路，對初次接觸的玩家略顯困難，但這反而也保留銀河戰士式探索風格的挑戰魅力。綜觀而言，這不僅是對一段經典系列的致敬，更讓這些優秀作品在新世代平台上得以重新發光，成為動作遊戲愛好者與洛克人粉絲必備的收藏之一。

Mega Man Zero/ZX Legacy Collection (Japanese title: ロックマン ゼロ&ゼクス ダブルヒーローコレクション) is a nostalgia-driven remaster released by CAPCOM in 2020, available on multiple platforms including Nintendo Switch. This compilation brings together six classic titles that originally appeared on the Game Boy Advance and Nintendo DS: Mega Man Zero 1 through 4, along with Mega Man ZX and ZX Advent. For longtime fans, it represents a precious return to a beloved series, while for newcomers, it serves as an ideal introduction to one of the most significant narrative branches in the Mega Man universe.

The story is set in a future era following the events of the Mega Man X series—a time dominated by mechanical lifeforms. The Zero series focuses on the character Zero, a major figure from the X series, who awakens from a century-long sleep in a chaotic future. Rescued by a young scientist named Ciel, he joins a resistance movement against the authoritarian regime of Neo Arcadia, a society initially established by X but now corrupted. The narrative across these four games is notably darker and heavier than previous entries, delving into themes of coexistence and the ethical dilemmas between humans and machines.

After the conclusion of the Zero saga, the ZX series picks up the timeline in the same universe. Unlike its predecessors, ZX introduces new protagonists—Van or Aile—young individuals who merge with “Biometals,” AI-based weapons infused with the wills of X and Zero. These characters embark on journeys of self-discovery while resisting control and disorder. The ZX titles place greater emphasis on personal choice and growth, and incorporate a more open-world map system with nonlinear mission structures, enhancing the exploration aspect of gameplay. The sequel, ZX Advent, expands on this with additional transformation abilities and more dynamic combat freedom.

In terms of gameplay, the collection remains remarkably faithful to the original mechanics. It retains the fast-paced, side-scrolling action that the series is known for. Zero’s signature quick slashes, wall jumps, and dashes, along with the ZX series’ transformation system and multi-directional shooting, all translate seamlessly to the Switch’s control schemes. CAPCOM has also introduced several quality-of-life improvements to accommodate modern players. A Casual Scenario Mode allows newcomers to take less damage and enjoy the story more easily, while Save Assist enables more frequent checkpoints throughout levels. Since the ZX games were originally dual-screen DS titles, the collection provides multiple display options to replicate the dual-screen experience in creative ways, showing particular care in adapting these games for modern consoles.

Visually, players are given the choice between retaining the original pixel art style or applying a smoothing filter for a more modern, high-resolution look. Regardless of the setting, the futuristic aesthetic of the series remains intact. The Zero games, in particular, are praised for their vivid combat animations and memorable boss designs.

Upon release, the collection was met with widespread acclaim globally. Many gaming outlets and fans praised it as one of CAPCOM’s most respectful remaster efforts. It not only preserves the authenticity of the originals but also enhances them with useful new features. The inclusion of classic music tracks, a “Gallery Mode” full of official artwork and illustrations, and the all-new Z Chaser mode—where players race through stages against the clock—add significant replay value, turning this into more than just a nostalgic repackage.

While some criticism was directed at the ZX games’ navigational system—specifically the unclear map guidance which may lead to confusion for first-time players—this is also seen by some as a deliberate homage to the “Metroidvania” style of exploration. Ultimately, Mega Man Zero/ZX Legacy Collection stands as both a heartfelt tribute to a classic era and a powerful reintroduction of these exceptional titles to a new generation. It’s an essential addition for action-platformer enthusiasts and a must-have for any Mega Man fan.
