《洛克人X 週年紀念合集2》（Rockman X Anniversary Collection 2，日文名：ロックマンX アニバーサリー コレクション2）是CAPCOM於2018年推出的復刻合輯，專為紀念《洛克人X》系列而打造，對應平台包括Nintendo Switch、PS4、Xbox One與PC。「週年紀念合集」的第二部分，收錄從《洛克人X5》到《X8》的四部作品，完整還原PS1與PS2時代的原始風貌，同時加入現代玩家友善的功能與補充內容。主要面向喜愛動作平台遊戲與經典洛克人系列的老玩家，但也為新玩家提供體驗X系列中後期風格與演進的機會。

劇情方面，延續初代洛克人的世界觀，但主角由原本的「洛克人」轉為更具戰鬥風格的「X」，一位擁有自由意志的高智能機器人。他與同伴Zero聯手對抗一波波被病毒感染或反叛的機器人，這些敵人被稱為「獵人叛變者（Mavericks）」。在《X5》至《X8》中，劇情逐漸變得更為黑暗與複雜，探討自由意志、犧牲與技術腐敗等主題。

劇情聚焦在「歐米加病毒（Sigma Virus）」大舉爆發，導致地球面臨毀滅。X與Zero必須阻止太空殖民地墜落地球的災難。《X6》延續前作事件，描寫Zero失蹤後X獨自作戰的艱難局面。《X7》則引入全新角色Axl，同時首次嘗試3D/2D混合玩法。《X8》回歸橫向捲軸並強化動作系統，講述地球人與機器人如何走向月球殖民計劃的過程中，再次爆發的新危機。

操作方面，這四部作品基本保留經典的橫向捲軸動作設計，核心玩法包括跳躍、牆跳、衝刺、蓄力射擊、吸收Boss能力等特色機制，並在不同作品中逐步演進。例如，《X5》和《X6》強調角色裝備與零件的配置策略；《X7》首次引入3D場景探索與自動鎖定射擊；而《X8》則回歸2.5D並強調角色切換與連段技能。每部作品都可以選擇X、Zero，部分還可使用新角色Axl，形成三位一體的操作體系。對喜愛挑戰與高技巧操控的玩家來說，這些作品提供豐富的關卡設計與多樣的戰鬥體驗。

合輯本身也加入一些現代功能，如「Boss Rush模式」、「劇情資料庫」、「原畫館」與「音樂播放器」，讓粉絲可以重溫系列歷史、欣賞美術設定，並聽取完整的系列原聲音樂。還提供「新人模式」與「自動儲存」等輔助設計，降低原作高難度對新玩家的門檻，讓更多人能順利通關體驗劇情。

在市場評價方面，獲得整體正面反應。玩家與評論普遍認為本作誠意十足，不僅忠實還原原始遊戲內容，也針對現代平台做出穩定移植與畫質優化。特別是《X8》的高畫質表現，在Switch平台上表現流暢，讓不少玩家驚喜。媒體則對《X7》的3D嘗試評價兩極，一方面肯定其創新意圖，但另一方面認為操作與鏡頭仍不夠成熟。然而，《X5》、《X6》和《X8》則被多數粉絲視為系列中後期的高峰之作，尤其是劇情深度與角色塑造在這些作品中逐步成熟，讓X系列更具敘事性與情感張力。

總結來說，《洛克人X 週年紀念合集2》是為懷舊玩家與動作遊戲愛好者打造的集大成之作。不僅保留X系列的經典玩法，也讓現代玩家有機會一探機器人與人性掙扎的未來敘事。儘管其中部分作品在當年原始發售時口碑不一，但作為完整的合集，仍成功地讓X系列得以延續並進入新世代玩家的視野。如果曾經喜愛洛克人，這套合集是值得重遊的經典之旅。

Mega Man X Legacy Collection 2 (Japanese title: ロックマンX アニバーサリー コレクション2, also known as Rockman X Anniversary Collection 2) is a remastered compilation released by Capcom in 2018 to celebrate the Mega Man X series. Available on Nintendo Switch, PlayStation 4, Xbox One, and PC, this second volume of the anniversary collection features Mega Man X5 through X8, faithfully preserving the original experience from the PS1 and PS2 eras while adding modern conveniences and bonus content. It’s primarily aimed at longtime fans of action-platformers and the Mega Man franchise, but it also provides a gateway for new players to explore the evolving style and tone of the latter half of the X series.

The storyline continues the Mega Man universe but shifts the spotlight from the original “Mega Man” to “X,” a highly advanced Reploid with free will. Alongside his companion Zero, X battles waves of Reploids infected by a mysterious virus or rebelling against humanity—these are the so-called “Mavericks.” From X5 to X8, the narrative takes on a darker and more complex tone, delving into themes like free will, sacrifice, and the corruption of technology.

The arc begins with the outbreak of the “Sigma Virus,” threatening Earth with destruction. X and Zero must stop a space colony from crashing into the planet (X5), followed by X6, where X fights alone after Zero’s disappearance. X7 introduces a new character, Axl, and attempts a hybrid 2D/3D gameplay approach. X8 returns to classic side-scrolling action in 2.5D, focusing on the colonization of the moon and a new crisis that emerges during humanity’s next step forward.

In terms of gameplay, all four titles maintain the core side-scrolling action formula that defines the series—jumping, wall-kicking, dashing, charged shots, and boss ability absorption. Each entry evolves this foundation: X5 and X6 emphasize character customization and equipment; X7 introduces 3D exploration and auto-lock shooting; X8 refines 2.5D visuals and expands on character switching and combo mechanics. Players can choose between X and Zero across the series, with Axl added to form a three-character system in X7 and X8. For fans of skill-based action, these entries offer rich level design and diverse combat experiences.

The collection also includes modern enhancements like “Boss Rush Mode,” a “Story Database,” a gallery of concept art, and a full music player to revisit the franchise’s iconic soundtrack. Accessibility options such as “Rookie Hunter Mode” and auto-save help lower the difficulty curve, making the collection more approachable for newcomers.

Critically, Mega Man X Legacy Collection 2 received generally positive reviews. Fans and critics praised the faithful recreation of the originals, the stability of the ports, and the visual upgrades—particularly X8, which runs smoothly on the Switch and surprised many with its performance. While X7’s 3D experimentation received mixed feedback—some appreciating the ambition, others criticizing its clunky controls and camera—the other titles, especially X5, X6, and X8, are often regarded as high points in the later series for their story depth and character development.

In summary, Mega Man X Legacy Collection 2 is a comprehensive package designed for nostalgia-seeking fans and action game enthusiasts alike. It preserves the core elements of the X series while making them accessible to a new generation of players. Despite varied reception during the original releases, this collection offers a cohesive way to experience the series’ evolution, exploring the ongoing conflict between technology and humanity. For anyone who once loved Mega Man, this is a classic journey worth revisiting.
