《航海王：海賊無雙3》（日文名：ワンピース 海賊無双3，英文名：One Piece: Pirate Warriors 3）是由Bandai Namco Entertainment發行、Omega Force開發的動作無雙類遊戲，最初於2015年在PlayStation平台發售，後於2017年登上Nintendo Switch平台。結合《航海王》原作漫畫的劇情與《無雙》系列的爽快割草玩法，兼具動漫粉絲向內容與動作遊戲系統的作品，屬於《海賊無雙》系列的第三作，亦是許多系列愛好者認為完成度與劇情覆蓋最為均衡的一部。

在劇情方面，延續前作風格，依然以《航海王》的原作漫畫為基礎，從主角魯夫在風車村出發開始，一路推進到「德雷斯羅薩篇」的多佛朗明哥決戰，囊括大量原作經典篇章，如「阿拉巴斯坦篇」、「司法島篇」、「頂上戰爭篇」等，完整描繪草帽海賊團一路走來的成長與冒險。特別著重於角色成長與情感連結，在劇情模式中重新體驗夥伴的加入過程與他們各自的信念，而非僅僅是戰鬥過程的重現。儘管劇情仍採快速推進的方式壓縮原作內容，但透過戰鬥與劇情動畫穿插的方式，有效讓粉絲重溫作品情懷，也讓新玩家能迅速了解整體故事脈絡。

操作上，承襲無雙系列的一貫設計，有魯夫、索隆、娜美、香吉士、羅、薩波等超過三十位可操作角色，以擊倒成百上千敵人為主要樂趣。採用簡易的輕重攻擊組合系統，透過連段與特殊技能發動，讓戰鬥充滿節奏感與視覺爽感。每位角色都保有原作中的專屬能力與必殺技，例如魯夫可使用「二檔」、「三檔」變形，索隆以三刀流展開範圍攻擊，甚至像薩波、羅等角色也能還原其火焰與空間切割招式。Switch版本特別針對掌機模式與雙人合作進行優化，Joy-Con分離即可進行本地雙人對戰，讓同台遊玩變得更加便利與有趣。

在進階系統方面，透過「夢幻對決模式」收集角色與卡片強化素材，逐步升級角色能力。各角色還有羈絆值設計，透過共同出戰提升情感連結，可解鎖額外技能與支援效果。這種角色間互動強化玩家對團隊的認同感，也帶來更豐富的養成層面。

市場評價方面，被許多玩家認為是《海賊無雙》系列的高峰之一。首先在內容廣度上，是首次真正將漫畫主線大幅度整合進遊戲的作品，篇章跨度與角色數量皆遠超前兩作。其次，戰鬥節奏、操作手感與畫面特效在Switch版上保有穩定表現，即使在掌機模式下仍可維持流暢的敵人數量與打擊反饋。特別是在掌機平台上，能夠重溫《航海王》的龐大世界觀本身就極具吸引力。

然而也有部分批評指出，在關卡設計上仍保留了不少「守點」、「擊敗指揮官」等無雙遊戲的傳統機制，重複度略高，容易在長時間遊玩後產生疲乏感。此外，劇情雖然忠於原作，但為配合關卡壓縮情節，有些角色的內心描寫與轉折略顯簡化，對熟知原作的玩家來說可能略感失落。

整體而言，《航海王：海賊無雙3》是為喜愛《航海王》的玩家量身打造的動作遊戲。在忠實重現原作劇情與角色魅力的同時，也透過爽快打擊感與角色養成系統打造出具娛樂性與收集感的遊戲體驗。無論是想重溫草帽一行人冒險旅程的老粉絲，還是初次接觸《海賊無雙》的新玩家，都能找到屬於自己的航海樂趣。

One Piece: Pirate Warriors 3 (Japanese title: ワンピース 海賊無双3) is a musou-style action game developed by Omega Force and published by Bandai Namco Entertainment. Originally released for PlayStation platforms in 2015, it later made its way to the Nintendo Switch in 2017. The game merges the narrative of the original One Piece manga with the exhilarating, enemy-sweeping gameplay of the Warriors series, making it a title that appeals to both anime fans and action game enthusiasts. As the third installment in the Pirate Warriors series, it is widely regarded by fans as the most balanced in terms of content completeness and story coverage.

The game’s story mode faithfully follows the plot of the One Piece manga, beginning with protagonist Monkey D. Luffy’s departure from Foosha Village and progressing all the way to the Dressrosa arc, culminating in the showdown with Doflamingo. Along the way, it covers many of the series' most iconic arcs, such as Alabasta, Enies Lobby, and the Paramount War. Emphasis is placed not only on battles but also on the emotional growth and bonds of the Straw Hat Pirates, allowing players to relive the moments when each crewmate joins Luffy’s journey. While the story is condensed to fit the game’s structure, the mix of cutscenes and real-time combat sequences successfully captures the spirit of the source material, providing both nostalgia for longtime fans and narrative clarity for newcomers.

In terms of gameplay, Pirate Warriors 3 stays true to the core mechanics of the Warriors series. Players can choose from over thirty playable characters, including Luffy, Zoro, Nami, Sanji, Law, and Sabo, mowing down hordes of enemies in large-scale battles. The combat system features accessible light and heavy attack combos, alongside powerful special techniques that bring dynamic rhythm and visual flair to the action. Each character retains their unique abilities from the manga, such as Luffy’s Gear Second and Gear Third transformations, Zoro’s Three-Sword Style, and even Sabo’s and Law’s distinctive fire and spatial manipulation skills. The Switch version is optimized for handheld play and local co-op, with split Joy-Con support allowing two players to team up on a single console for cooperative battles, enhancing accessibility and shared enjoyment.

The game also includes a progression system that adds depth to the experience. In the “Dream Log Mode,” players can collect materials and cards to strengthen their characters. The bond system enables characters to develop support skills and unlock special interactions by fighting together, encouraging teamwork and offering an additional layer of customization and replayability.

Critically and commercially, Pirate Warriors 3 is often hailed as the peak of the series. It is the first entry to comprehensively integrate the manga's storyline into a video game format, with a breadth of characters and scenarios that surpass its predecessors. On the Switch, the game performs reliably, maintaining smooth enemy rendering and responsive controls even in handheld mode. The ability to explore the vast One Piece universe on a portable console is a major draw for fans, making it an ideal title for on-the-go play.

Nonetheless, some criticisms have been raised. The level design still relies heavily on traditional musou tropes like base defense and commander eliminations, which can lead to repetitive gameplay during extended sessions. Moreover, while the story remains largely faithful to the manga, certain emotional nuances and character developments are inevitably simplified due to time and structural constraints, which may disappoint players deeply familiar with the original narrative.

Overall, One Piece: Pirate Warriors 3 is a game crafted for fans of the One Piece franchise. It delivers a satisfying blend of faithful storytelling, flashy combat, and character development systems. Whether you're a long-time follower of the Straw Hat crew looking to relive their legendary journey, or a newcomer curious about the Pirate Warriors experience, this title offers a compelling and action-packed voyage through one of anime’s most beloved worlds.
