《洛克人世界》（ロックマンワールド / Mega Man: Dr. Wily’s Revenge）是卡普空於1991年推出、由外包公司Minakuchi Engineering負責開發的掌機版《洛克人》系列第一作，同時也是Game Boy平台上最具代表性的動作遊戲之一。這部作品在系列歷史中具有劃時代意義，因為它成功地將紅白機上的《洛克人》風格完美移植到掌上型遊戲機中，並成為之後四款《洛克人世界》續作的起點。

在故事方面，延續主系列的世界觀。由萊特博士（Dr. Light）所製造的超級機器人洛克人（Mega Man），一再挫敗邪惡天才威利博士（Dr. Wily）征服世界的陰謀，讓人類重獲和平。然而，野心勃勃的威利博士並未就此死心，他暗中改造萊特博士原本設計用於工業用途的機器人，並打造出一支新的戰鬥機器人軍團，再度向世界展開侵略。為了阻止威利的陰謀，洛克人再次披上戰甲，踏上戰場。這次，威利博士甚至製造一個專門為對抗洛克人而設計的特殊戰鬥型機器人──恩克（Enker），使得戰局更加艱險。

遊戲流程採用經典的關卡選擇系統，最初可以挑戰來自《洛克人1》的四名頭目：剪刀人（Cut Man）、冰人（Ice Man）、火焰人（Fire Man）與電氣人（Elec Man）。每打倒一位頭目後，便能獲得其專屬武器。當這四名頭目全數被擊敗後，選關畫面中央會出現威利城（Wily Castle），進入後將遭遇來自《洛克人2》的四名頭目──氣泡人（Bubble Man）、快手人（Quick Man）、閃光人（Flash Man）與熱火人（Heat Man）。最後，洛克人會與恩克展開最終決戰。恩克的武器「鏡面破壞炮（Mirror Buster）」能吸收洛克人的攻擊並反射回去，戰鬥難度相當高。擊敗恩克後，洛克人追擊威利至太空中的威利要塞，最終利用鏡面破壞炮將威利打敗，成功粉碎他的陰謀。

在操作方面，以初代《洛克人》的系統為基礎，保留系列經典的橫向卷軸射擊與跳躍動作。與後期作品不同，並沒有滑行（Slide）或E罐（Energy Tank）等功能。大部分特殊武器的發射動作經過修改，變成類似投擲的姿勢。血量與武器能量也被縮減為19格，而非家用機版的28格，使得整體節奏更加緊湊。

選單系統採用全畫面設計，特殊武器的名稱以兩個字母簡寫顯示（如「CU」代表Cut Man的武器），這種簡潔的設計後來成為整個《洛克人世界》系列的標準配置。遊戲在關卡完成後無法重返已破關的場景，這與家用機版本不同，也使得必須謹慎規劃武器使用與能量分配。此外，威利城階段具有特別的機制：若玩家在後半關卡Game Over，將會被送回選關畫面並失去在威利城中取得的所有特殊武器，這使得《洛克人世界》成為系列中唯一能「失去武器」的作品。

視覺與音樂方面，雖然受限於Game Boy的單色顯示，但依舊成功還原《洛克人》系列的魅力。角色與敵人精緻的像素圖像，以及細膩的場景設計，讓玩家在小螢幕上也能感受到強烈的動作張力。音樂則以8位元音效重製了原作曲目，節奏明快且旋律鮮明，被許多老玩家視為Game Boy平台上最具代表性的遊戲配樂之一。

在市場評價方面，發售後取得極大的成功。由於完美融合家用機的精髓與掌機特有的便攜性，在玩家之間引起熱烈迴響，首批出貨即突破百萬套銷量，後來甚至被再版為「Player’s Choice」名作。評論者普遍讚賞遊戲的關卡設計、武器平衡與操作手感，並認為這是當時Game Boy上最具完成度的動作遊戲之一。

此作不僅奠定《洛克人世界》系列的基礎，也讓Minakuchi Engineering獲得卡普空的信任，之後接手製作《洛克人世界2》至《洛克人世界5》等多部作品。隨著時間推移，本作仍被視為Game Boy經典之一。2011年6月7日，以原汁原味的形式登上3DS Virtual Console；2024年6月7日，又被加入Nintendo Switch Online Game Boy遊戲庫，讓新世代玩家得以再次體驗這款復古傑作的魅力。

總結來說，《洛克人世界》不僅是《洛克人》系列首次成功移植至掌機的代表作，更是Game Boy時代象徵性的動作遊戲之一。在保持系列核心精神的同時，加入適合掌機節奏的調整，為後續掌機動作遊戲奠定重要範例，至今仍被許多玩家懷念為「最純粹的洛克人體驗」。

Mega Man: Dr. Wily’s Revenge (Japanese title: ロックマンワールド / Rockman World) is the first handheld entry in Capcom’s legendary Mega Man series, released in 1991. Although published by Capcom, the game was developed by the contracted studio Minakuchi Engineering. It became one of the most iconic action games on the Game Boy platform, marking a turning point in the franchise’s history for its successful adaptation of the Famicom’s Mega Man gameplay and spirit into a portable format. It would also go on to lay the foundation for four handheld sequels in the Rockman World line.

The story continues directly from the main series universe. After countless battles where the super robot Mega Man—created by the brilliant Dr. Light—thwarted the world domination plans of the evil genius Dr. Wily, peace returned to humanity. Yet Wily’s ambitions never ceased. Working in secret, he reprogrammed Dr. Light’s industrial robots into combat units and built a new army of war machines, once again threatening the world. To stop his schemes, Mega Man dons his armor and heads into battle. This time, however, Dr. Wily has created a special combat robot specifically designed to counter Mega Man—Enker—a formidable foe who turns the tide of battle with his reflective weapon, the Mirror Buster, capable of absorbing Mega Man’s shots and sending them back with devastating power.

The gameplay follows the classic Mega Man structure, allowing players to choose their starting stage. The first four bosses—Cut Man, Ice Man, Fire Man, and Elec Man—are taken from the original Mega Man. Defeating each boss grants Mega Man their unique weapon, which can then be used strategically against others. Once these four are conquered, the central stage on the selection screen unlocks Wily’s Castle, featuring four additional bosses from Mega Man 2: Bubble Man, Quick Man, Flash Man, and Heat Man. The final showdown takes place against Enker, followed by a climactic space battle in Wily’s fortress, where Mega Man ultimately defeats Wily using the Mirror Buster and restores peace once more.

In terms of controls, the game retains the foundation of the original Mega Man’s side-scrolling run-and-gun mechanics. However, it omits later features such as the Slide move and Energy Tanks (E-Tanks). Many of the special weapons feature new throwing-style animations, and both Mega Man’s health and weapon energy are reduced to 19 units (from the console version’s 28), tightening the overall game pace.

The weapon selection screen adopts a full-screen menu design, displaying abbreviated two-letter weapon codes (such as “CU” for Cut Man’s weapon). This minimalist interface later became the standard across the Rockman World series. Unlike the console versions, stages cannot be revisited once cleared, encouraging players to manage their resources carefully. Additionally, Wily’s Castle introduces a unique mechanic: if the player receives a Game Over during the later stages, they are sent back to the stage selection screen and lose all weapons acquired within the castle—making this the only Mega Man title in which weapons can be permanently lost.

Visually and musically, the game makes impressive use of the Game Boy’s limited monochrome display. Despite hardware constraints, it preserves the charm of the console series with detailed pixel art and well-crafted environments that deliver a strong sense of action even on a small screen. The music, adapted from the NES originals into crisp 8-bit compositions, maintains a lively rhythm and memorable melodies. Many long-time fans consider its soundtrack one of the most recognizable and beloved on the Game Boy.

Upon release, Mega Man: Dr. Wily’s Revenge achieved significant commercial success. It captured both the essence of the console titles and the portability of handheld gaming, quickly selling over one million copies and later reissued as part of the “Player’s Choice” label. Critics praised its level design, weapon balance, and responsive controls, calling it one of the most polished and complete action titles available on the Game Boy at the time.

The game’s success solidified Minakuchi Engineering’s relationship with Capcom, leading the studio to develop Mega Man World 2 through Mega Man World 5 in subsequent years. Even decades later, Dr. Wily’s Revenge remains celebrated as a defining Game Boy classic. It was re-released in its original form on the Nintendo 3DS Virtual Console on June 7, 2011, and again on Nintendo Switch Online’s Game Boy library on June 7, 2024, allowing a new generation of players to experience this retro masterpiece.

In summary, Mega Man: Dr. Wily’s Revenge is not only the first successful handheld adaptation of the Mega Man franchise but also a landmark title of the Game Boy era. By maintaining the series’ core spirit while fine-tuning the gameplay for portable pacing, it became a model for future handheld action games and is still fondly remembered today as one of the purest Mega Man experiences ever made.
