《SD 鋼彈 G 世代 火線縱橫》（日文名：SDガンダム ジージェネレーション クロスレイズ，英文名：SD Gundam G Generation Cross Rays）是由萬代南夢宮（Bandai Namco）發行的戰略模擬角色扮演遊戲，於2019年推出，Nintendo Switch版本同步發售。鋼彈系列中的《G Generation》分支之一，延續該系列將多部鋼彈動畫作品集結在同一遊戲中、讓玩家自組夢幻部隊參戰的基本風格。其最大特色，是專注於「宇宙世紀以外」的四部非UC系作品——《機動戰士鋼彈W》、《機動戰士鋼彈SEED》、《機動戰士鋼彈00》與《機動戰士鋼彈鐵血孤兒》，包含這些作品的主線劇情與衍生OVA、外傳小說內容。

劇情方面，採取章節式關卡結構，每部鋼彈作品以「Generation」單元呈現，自由選擇從哪一部作品開始。每個單元忠實還原原作劇情，包含重要戰役、角色名言、經典場景與劇情轉折，並以過場動畫與語音演出補足劇情深度。可以逐步參與如「利歐 VS 威塔」的激戰、「強化人與自然人之爭」、「殘酷的火星童兵革命」等橋段，對於熟悉鋼彈原作的粉絲而言，這些場景與角色的互動非常具有情懷。

操作與系統層面上是回合制戰棋玩法。戰場以方格形式呈現，每回合可指令我方單位移動、攻擊、防禦、使用技能或進行聯合攻擊。從上百架鋼彈機體與駕駛員中組建小隊，每架機體有其射程、武器、EN能量值與耐久度，駕駛員則有專屬技能與能力值影響戰況。特別的是，導入細緻的「開發與設計」系統，讓玩家不只收集現有機體，還能藉由機體的升級與進化，解鎖其他更高階型號。例如讓一架初期型鋼彈逐步升級為高性能改造型，甚至透過設計功能創造全新機體。

戰鬥系統方面，延續系列的「鏈接攻擊（Link Up）」與「支援攻擊」概念，能讓隊伍之間彼此支援造成連鎖傷害。此外，組建「艦隊編成」，安排戰艦與隊員的搭配，並配置特殊戰術指令（如廣域修復、集中砲擊等），增加作戰深度。地圖中的任務目標也有主、次條件區分，完成隱藏挑戰可獲得更高報酬與稀有單位，使遊戲的重玩性極高。

Switch版本針對掌機與TV模式皆有優化，在介面上更適合觸控操作與快速切換單位指令。圖像則為SD比例的3D模組，戰鬥演出雖非寫實風格，但招式特效流暢華麗，例如自由鋼彈的光束亂舞、能天使高達的TRANS-AM發動，都以動畫風表現忠實再現原作氣勢。

市場評價方面，獲得相當穩定的中上評價。在Metacritic上，Switch版本平均分數約落在71分之間。粉絲與媒體普遍認為，這是《G Generation》系列近年最完整、最具戰略深度的作品，收錄單位豐富、角色語音齊全，對鋼彈粉絲尤其是非UC系愛好者而言是一場盛宴。許多玩家讚賞其對四部作品的細膩再現與大量支線機體的可收集性，加上機體開發路線清晰易懂，構成十分耐玩的軍武收集體驗。

不過，也有評論指出本作對新玩家可能稍顯門檻過高，操作介面略為複雜，教學部分不夠直觀。某些關卡節奏偏慢，導致遊戲前期體驗略顯冗長。此外，未包含宇宙世紀作品，對只熟悉初代、高達Z或逆襲的夏亞等經典粉絲來說吸引力可能不如以往的G世代大集合版本。

總結而言，《SD 鋼彈 G 世代 火線縱橫》是內容豐富、策略深度高且充滿情懷的戰棋SRPG作品，尤其對於熟悉《鋼彈W》《SEED》《00》與《鐵血孤兒》的玩家而言幾乎是必玩之作。雖然在節奏與系統複雜度上對初學者不那麼友善，但一旦熟悉機體育成與戰術配置後，便能享受到高度自由與成就感兼具的鋼彈戰場體驗。如果有喜歡的鋼彈作品，可以用自己的方式改寫戰場歷史。

SD Gundam G Generation Cross Rays (Japanese title: SDガンダム ジージェネレーション クロスレイズ) is a strategy simulation RPG published by Bandai Namco, released in 2019 with a simultaneous launch on the Nintendo Switch. As a part of the G Generation spin-off within the larger Gundam franchise, the game continues the tradition of bringing together multiple Gundam anime series into one crossover battlefield, allowing players to assemble their dream squads. What sets this entry apart is its exclusive focus on four non-Universal Century (non-UC) series: Mobile Suit Gundam Wing, Mobile Suit Gundam SEED, Mobile Suit Gundam 00, and Mobile Suit Gundam: Iron-Blooded Orphans. It covers not only the main storylines but also side stories, OVAs, and novel adaptations from these franchises.

The game adopts a chapter-based stage structure, with each Gundam series presented as a self-contained “Generation” scenario, allowing players to freely choose where to start. Each unit faithfully recreates the original plot, including key battles, famous quotes, iconic scenes, and major story twists, enriched through animated cutscenes and voiced dialogue. Players can relive dramatic moments such as “Leo vs. Wing Gundam,” conflicts between Coordinators and Naturals, or the tragic uprising of Martian child soldiers. For longtime fans, these storylines and character interactions deliver a strong sense of nostalgia.

In terms of gameplay mechanics, Cross Rays utilizes a turn-based tactical grid system. The battlefield is laid out on tiles, with players commanding units to move, attack, defend, activate skills, or initiate team-based combo attacks. Squads are formed from a vast roster of Gundam units and pilots, each with specific attack ranges, weapon types, EN (energy) levels, and durability stats. Pilots contribute their own skill sets and stats that influence the tide of battle. A notable feature is the detailed “Development and Design” system, which allows players not only to collect existing mobile suits but also to evolve and upgrade them into higher-tier versions. For example, a basic mobile suit can be progressively enhanced into an elite variant, or even designed into an entirely new custom unit.

The combat system retains the franchise’s signature mechanics like “Link Up Attacks” and “Support Attacks,” enabling chain damage through strategic team coordination. Fleet formation plays a key role as well—players organize ships, assign crew members, and use tactical commands such as wide-range healing or concentrated bombardments. Missions often feature primary and secondary objectives, with hidden challenges that unlock rare units and better rewards, adding high replay value.

The Switch version is optimized for both handheld and TV modes, with an interface designed for intuitive touch controls and quick command switching. Visually, it uses SD-style 3D models; while not hyper-realistic, the animations are fluid and flashy. Signature attacks—like Freedom Gundam’s beam barrage or Exia’s TRANS-AM activation—are brought to life with vibrant visual effects that stay true to the source material’s flair.

In terms of reception, the game received generally favorable mid-to-high reviews. On Metacritic, the Switch version averages around a score of 71. Critics and fans alike consider it one of the most complete and strategically rich G Generation titles in recent years. With a wide variety of units, fully voiced characters, and a strong focus on four fan-favorite non-UC series, it has been celebrated as a must-have for dedicated Gundam enthusiasts. Many players praised the faithful recreation of story arcs, the sheer collectibility of side units, and the approachable yet deep development trees, which combine to deliver a highly satisfying mecha strategy experience.

However, some criticism has been directed at the game’s steep learning curve for newcomers. The interface can be complex, and the tutorial system is not as intuitive as it could be. Certain early stages can feel slow-paced, potentially making the initial hours somewhat tedious. Additionally, the game does not feature any Universal Century content, which may lessen its appeal to fans of classic Gundam series like Mobile Suit Gundam, Zeta Gundam, or Char’s Counterattack, who are used to the broader crossover lineup of past G Generation entries.

In summary, SD Gundam G Generation Cross Rays is a content-rich, emotionally resonant strategy RPG that offers significant tactical depth. It is especially recommended for fans of Gundam Wing, SEED, 00, and Iron-Blooded Orphans. While its systems can be overwhelming at first, those who master unit development and strategic team-building will find a rewarding experience packed with customization and high-stakes battles. If you have a favorite Gundam series, this game gives you the tools to rewrite its history your way.
