《虹彩六號：圍攻行動X》是由Ubisoft Montreal開發，Ubisoft發行的戰術團隊射擊遊戲，也是系列以來最具突破性的重大更新。自2015年12月2日首次發售以來，以高度策略性、真實感及緊張的對戰氛圍聞名，這次的「圍攻行動X」則徹底刷新玩家體驗，讓這款遊戲再度成為射擊遊戲領域中的焦點。

此次更新最受矚目的，就是全新加入的「雙重戰線」模式。這是永久性的6對6戰鬥玩法，與以往經典的5對5對抗相比，規模更大、戰術更多元。自由選擇混搭進攻方與防守方的幹員，除必須保衛己方區域，還要設法奪取敵方區域。對戰中，角色死亡後可以重生並更換幹員，甚至還能執行高風險的「中立區」任務，這些設計大幅增加比賽的動態變數與戰術深度。

在畫面與遊戲細節方面，同樣展現革新的決心。包括「俱樂部會所」、「木屋」、「邊境」、「銀行」與「咖啡館」等經典地圖，都進行現代化重製，不僅提升光影、解析度，整體氛圍也更加真實，未來每季還會陸續推出更多翻新地圖。物理破壞系統也更進一步，瓦斯管線、金屬探測器與滅火器等新物件都能成為戰術工具。繩索垂降的操作更流暢，能靈活橫移或繞過建築轉角，增加突入與反制的可能性。音效亦全面升級，回音與聲音傳播效果更加真實，透過聲音來判斷敵人位置與房間類型，使情報蒐集更具臨場感。

除核心玩法的革新，新手玩家的入門體驗也獲得全面重構。全新的等級進程與訓練系統，幫助新玩家逐步建立技巧與信心，讓他們更快適應緊張刺激的戰場氛圍。另一方面，也引入新的「挑選與禁用」系統，以及強化版的「R6 ShieldGuard」反作弊機制，讓比賽環境更公平。

在商業模式上，維持免費遊玩的基礎設計。新玩家可免費體驗快速對戰、非排名戰及雙重戰線模式，並能使用部分精選幹員。而付費版本則提供更多選擇，例如「菁英版」能解鎖所有遊戲模式及16名幹員，「終極版」則進一步提供52名幹員及額外裝備組合，滿足追求完整體驗的玩家。現有玩家的既有內容與解鎖幹員都將保留，並會依照加入年份獲得專屬獎勵。

值得一提的是，本次更新還同步推出第10年第2季「破曉行動」，其中重新設計Clash幹員，使其標誌性的「CCE 護盾」可以被固定部署，並能遠端操作電擊敵人。此外，整體平衡性也進行調整，包括電擊不再對幹員造成傷害，以及Jackal、Sledge、Thunderbird、Jäger 與 Blackbeard等幹員的數據優化。

整體而言，《虹彩六號：圍攻行動X》不僅是例行更新，而是對整個遊戲生態的大革新。不只提升視覺與操作體驗，更透過模式與系統的創新，賦予玩家更多策略自由度與挑戰性。對於老玩家而言，這是一場回歸的最佳時機；對新玩家來說，這則是進入《虹彩六號》世界的黃金契機。這場更新，無疑再次將本作推上戰術射擊遊戲的巔峰。

Rainbow Six Siege X is a tactical team-based shooter developed by Ubisoft Montreal and published by Ubisoft, marking the most groundbreaking update in the history of the franchise. Since its initial release on December 2, 2015, the game has been renowned for its strategic depth, realism, and intense competitive atmosphere. With the arrival of Siege X, the player experience has been completely refreshed, reaffirming the game’s status as a centerpiece in the world of tactical shooters.

The most notable addition in this update is the brand-new “Double Frontline” mode, a permanent 6v6 battle system that expands upon the classic 5v5 format. This mode introduces larger-scale confrontations and more diverse tactical options. Players can freely mix and match operators from both attacking and defending sides. In addition to defending their own territory, they must also capture enemy zones. Unlike traditional elimination rounds, operators can now respawn, switch roles mid-match, and take on high-risk “Neutral Zone” missions, adding new layers of unpredictability and dynamic strategy to each encounter.

Visually and technically, Siege X demonstrates Ubisoft’s commitment to innovation. Classic maps such as Clubhouse, Chalet, Border, Bank, and Kafe Dostoyevsky have been modernized with improved lighting, shadows, and resolution, creating a more immersive environment. Future seasonal updates will continue to roll out additional reimagined maps. The destruction system has also been expanded, allowing interaction with new elements such as gas pipelines, metal detectors, and fire extinguishers, turning the environment itself into tactical tools. Rope rappelling has been refined, enabling smoother lateral movements around building corners. On the audio front, soundscapes have been completely overhauled with realistic echo and sound propagation, making audio cues even more vital for identifying enemy positions and room layouts.

For newcomers, the onboarding experience has been redesigned with a structured progression path and training system, helping players steadily build confidence and skills before entering high-intensity battles. Competitive integrity has also been strengthened with the introduction of a new Pick & Ban system and the upgraded R6 ShieldGuard anti-cheat mechanism, ensuring a fairer playing field.

On the business side, Siege X maintains its free-to-play foundation. New players can access Quick Matches, Unranked, and Double Frontline modes with a selection of operators at no cost. Paid editions expand the experience further: the Elite Edition unlocks all game modes plus 16 operators, while the Ultimate Edition includes 52 operators along with exclusive equipment bundles. Existing players will keep all previously unlocked content and receive exclusive veteran rewards based on their years of activity.

The update also coincides with the launch of Year 10, Season 2: Operation Dawn, featuring a redesigned Clash operator. Her signature CCE Shield can now be deployed as a stationary device and remotely controlled to deliver electric shocks. Game balance adjustments have also been made, including the removal of friendly damage from electric shocks and stat reworks for operators such as Jackal, Sledge, Thunderbird, Jäger, and Blackbeard.

Overall, Rainbow Six Siege X is far more than a routine patch—it represents a fundamental evolution of the game’s ecosystem. By enhancing visuals, gameplay mechanics, and tactical freedom, Ubisoft has raised the stakes for both veteran and new players alike. For long-time fans, this is the perfect moment to return; for newcomers, it is the ideal entry point into the Rainbow Six universe. This update firmly cements the title once again at the pinnacle of tactical shooters.
