《洛克人世界3》（Rockman World 3 / Mega Man III）是掌機平台上洛克人系列的第三部作品，由外包廠商Minakuchi Engineering開發，Capcom發行，於1992年12月11日在日本和北美同步推出。延續洛克人世界系列的傳統玩法，將玩家置於動作平台的挑戰中，但同時引入集氣射擊的新機制，使洛克人的攻擊方式更具策略性。遊戲整體難度偏高，尤其是敵人的耐久度較高、關卡設計需要精準操作，因此被認為是洛克人世界系列中最具挑戰性的一作。

延續經典的反派威利博士陰謀。故事背景設定在上一場與威利博士的戰鬥幾個月後，萊特博士的研究所收到一則壞消息：全球管理工業、交通和氣象的超級電腦發生異常，城市陷入混亂，同時武裝機器人趁機攻擊各地。萊特博士調查發現，這些異常源於未知妨害電波，而幕後正是威利博士在操控。洛克人將前往各個受侵襲的城市，擊退入侵的機器人軍團，逐步追查妨害電波的來源，最終對抗威利博士及其設計的新型機器人「龐克」，恢復世界秩序。

在玩法方面，洛克人世界3結合《洛克人3》和《洛克人4》的內容，每部作品各提供四個頭目，再加上兩關原創的威利博士關卡，玩家可以在前四個頭目中自由選擇挑戰順序。洛克人的主要攻擊方式是「Mega Buster」，可以發射無限小型射擊，或透過長按蓄力釋放更強大的能量彈。此外，可以召喚愛弟（Eddie）和寵物機器人Rush輔助作戰，Rush可變形成「彈簧模式」讓洛克人跳得更高，或「噴射模式」在關卡中飛行，Eddie則會隨機提供道具、能量罐或額外生命，幫助玩家應對各種挑戰。

音樂主要重新編曲自洛克人3和洛克人4，特別是在關卡選擇畫面及頭目介紹畫面上使用洛克人4的音樂，這也是洛克人世界系列中唯一使用傳統頭目介紹畫面音樂的作品。還首次引入愛弟作為固定的關卡輔助角色，在探索中能獲得隨機道具。在挑戰過程中可以多次進入已擊敗頭目的關卡，但進入後半戰時無法返回前半戰關卡。

本作還加入威利城作為中繼關卡，在擊敗前半四大頭目後會進入威利城，突破後則進入後半四大頭目的選關畫面。擊敗後半四大頭目後，威利城再次出現在選關畫面，最終強制進入威利基地挑戰結局關卡。值得一提的是，原創頭目龐克可以被所獲得的特殊武器攻擊，這在洛克人世界系列中十分罕見。

在市場評價方面，受到玩家和評論家的肯定，尤其是其高難度關卡、策略性集氣射擊以及對掌機平台操作精度的要求，使其在洛克人粉絲中保持經典地位。雖然部分玩家認為遊戲難度偏高，有時令人挫折，但對喜愛挑戰和策略的玩家來說，它提供極具成就感的遊戲體驗。總體而言，《洛克人世界3》在掌機平台上成功延續洛克人系列的核心魅力，並成為系列中最具挑戰性且值得收藏的作品之一。

Mega Man III (Rockman World 3 / ロックマンワールド3) is the third handheld entry in the Mega Man World series, developed by Minakuchi Engineering and published by Capcom for the Game Boy. Released on December 11, 1992 in Japan and North America, the game continued the portable line of the Mega Man franchise, maintaining the action-platform gameplay of its predecessors while introducing new mechanics—most notably, the chargeable Mega Buster. However, due to tougher enemies and stage designs requiring precise control, it is widely regarded as the most difficult entry in the Game Boy Mega Man World series.

The story takes place several months after Mega Man’s previous battle against Dr. Wily. Dr. Light’s laboratory receives alarming reports: a massive supercomputer, responsible for managing the world’s industries, weather systems, and transportation networks, has malfunctioned, causing chaos across the globe. Taking advantage of the confusion, an army of rogue robots begins attacking cities. Dr. Light discovers that the disturbances are being caused by mysterious jamming waves, and he suspects that Dr. Wily is once again behind the chaos. To restore peace, Mega Man sets off to defeat the rampaging robots, trace the source of the interference, and put an end to Wily’s latest scheme.

The gameplay structure in Mega Man III follows the traditional Mega Man formula, combining elements from the NES titles Mega Man 3 and Mega Man 4. Players can freely select among four initial Robot Masters—Gemini Man, Snake Man, Shadow Man, and Spark Man—and upon defeating them, gain access to four more bosses from Mega Man 4: Dive Man, Drill Man, Dust Man, and Skull Man, before ultimately facing Wily’s fortress.

Mega Man’s main weapon, the Mega Buster, allows him to fire unlimited small energy shots or charge up a powerful blast by holding down the attack button. Defeating each Robot Master grants Mega Man their unique weapon, expanding tactical options in later stages. He is also assisted by his robotic companions—Rush, who can transform into a springboard (Rush Coil) or jet (Rush Jet) to help traverse stages, and Eddie, a helper robot who appears at certain points to deliver random items such as health refills, weapon energy, extra lives, or E-Tanks.

Musically, Mega Man III features rearranged tracks from Mega Man 3 and Mega Man 4, with the stage select and boss introduction themes adapted directly from Mega Man 4. This installment is also notable for being the only Mega Man World game to use the traditional boss introduction music from the main series. Eddie makes his first appearance here, marking the beginning of his recurring role as an item-delivering helper throughout the series.

The game introduces several unique mechanics for the Game Boy platform. Players can revisit previously cleared stages, although once entering the second half of the game, backtracking to earlier levels is not possible. After defeating the first four bosses, Wily’s Fortress appears at the center of the stage select screen. Clearing this area unlocks the next set of Robot Masters, and upon defeating all eight, Mega Man proceeds to Wily’s base for the final showdown. Notably, the original boss Punk, designed as a “Mega Man Killer,” can actually be damaged by his own special weapon—something unique within the handheld series.

Upon release, Mega Man III received positive reviews from both critics and fans. It was praised for its improved visuals, tighter gameplay, and deeper combat mechanics compared to earlier handheld entries. However, its high difficulty drew mixed reactions—some players found the challenge rewarding, while others considered it overly punishing. Despite this, Mega Man III remains a standout title in the Game Boy lineup, celebrated for refining classic Mega Man gameplay into a compact yet challenging form, and is often cited as one of the most technically impressive and memorable handheld entries in the entire franchise.
