《信長之野望・新生 with 威力加強版 Complete Edition》（日文：信長の野望・新生 with パワーアップキット）由日本光榮特庫摩（Koei Tecmo）開發的戰略模擬遊戲，是其經典歷史模擬系列《信長之野望》的第16部本傳作品《新生》的完全版合集，支援PS5與Nintendo Switch 2平台。整合原版《新生》與後續推出的《威力加強版》全部內容，並針對次世代平台進行畫質強化、操作優化與AI提升，被視為系列在戰略系統與劇情還原度上的一次全面進化。

劇情圍繞日本戰國時代，扮演織田信長或其他戰國大名之一，帶領自己的家族與勢力在群雄割據的亂世中逐步擴張領土，最終完成「天下布武」的統一大業。不同於以往強調武力征服的方式，更強調「自治與信任」的政治系統，導入「家臣自主行動」與「領地經營」的概念。可以任命地方武將擔任領主，讓他們根據AI與忠誠度自行經營城下町、建設農田、徵兵與防衛，形塑出真正的“群體政權”格局，而不再只是中央指令式操作。還追加包含「信長誕生」6個新故事，以及大規模的「決戰」。

在《威力加強版》中，新增多項重大系統與內容，最受好評的是「政策制訂」、「地方流通」、劇情「編輯功能」、「變更國家」與「新事件劇情」。透過政策制訂，依據家風、內政風格選擇不同治理方針，例如重商主義或軍事主義，而不同政策會影響家臣發展、稅收與外交傾向；地方流通則讓玩家能與鄰國進行交易、建設貿易路線，使整體經濟系統更具深度；新增劇情事件如「本能寺之變」「川中島決戰」、「關原之戰」等，採用全語音演出與插畫，提升歷史臨場感，也豐富角色性格與動機描寫。

操作方面，支援手把與觸控雙模式介面，無論在PS5還是Switch 2上皆能快速操作地圖、單位與政令指令，且UI設計更簡潔直觀。戰鬥系統仍延續系列傳統，以實時地圖上指令戰鬥為主，並強化「會戰」機制，在特定重大戰場如長篠或小牧長久手，會進入獨立戰術地圖進行分隊布陣與陣型操作，極大提高戰術自由度。加上天氣、地形與士氣影響因素，使得每場會戰既考驗布局，也兼具歷史趣味。

在畫面呈現方面，PS5版本支援4K解析與高幀率表現，戰場與城鎮建模細緻，家臣角色立繪採用新繪風，融合傳統與現代風格，而Switch 2版本則保有較高的可攜性與操作流暢性，適合長時間進行策略模擬操作的玩家。音效部分收錄古風配樂與戰國風語音，劇情演出全程搭配語音朗讀與過場插圖，讓歷史氛圍更具沉浸感。

市場評價方面，在原始版本推出時獲得玩家與評論界普遍好評，特別是其「家臣自主行動」系統被認為大幅提升中後期遊戲體驗，減輕玩家操作負擔，也增加每局劇本的變化性與可重玩性。威力加強版更擴充戰略層面的深度與歷史事件的還原，被視為該系列歷來最接近“真實戰國”的作品之一。在日本亞馬遜、Gamer.ne.jp等平台獲得高分評價，也登上日本多個PS5與Switch策略遊戲銷售榜。部分玩家認為AI表現仍有改進空間，但整體內容完整度與可玩性遠勝前作。

綜合而言，《信長之野望・新生 with 威力加強版 Complete Edition》不僅是光榮對戰國時代歷史模擬的一次集大成之作，更是系列老玩家與歷史迷不能錯過的戰略佳作。它在保有系列傳統深度的基礎上，引入更多智能化、自動化與沉浸化設計，讓戰國世界更加立體，讓玩家在沙盤推演之餘，也能親歷那段群雄並起、英雄逐鹿的時代榮光。

Nobunaga’s Ambition: Rebirth with Power-Up Kit Complete Edition (Japanese: 信長の野望・新生 with パワーアップキット) is a grand strategy simulation game developed by Koei Tecmo, renowned for its long-standing historical sim series. This edition serves as the definitive version of the 16th mainline title Rebirth in the Nobunaga’s Ambition franchise, and is available on PS5 and Nintendo Switch 2. It bundles the original Rebirth with all content from the subsequent Power-Up Kit, and introduces enhanced visuals, improved controls, and upgraded AI optimized for next-generation hardware. The game is widely regarded as a significant evolution in both its strategic systems and historical narrative presentation.

Set during Japan’s turbulent Sengoku period, the game places players in the role of Oda Nobunaga or another feudal lord, guiding their clan through an era of war and political upheaval with the goal of unifying the nation under the ideal of Tenka Fubu (rule of the realm by military force). While past entries focused heavily on military conquest, Rebirth emphasizes a more nuanced approach based on "autonomy and trust," introducing mechanics such as autonomous vassal behavior and domain governance. Players can appoint regional commanders who, influenced by AI and loyalty levels, manage castle towns, develop agriculture, conscript troops, and defend borders independently—creating a living "decentralized regime" rather than a micromanaged empire.

This complete edition also adds six new historical scenarios, including The Birth of Nobunaga, and large-scale "decisive battles" that reshape military encounters. The Power-Up Kit further enhances the game with significant systems and content: policy formulation, regional trade networks, a custom scenario editor, the ability to switch nations mid-game, and new historical events. With the policy system, players can adopt domestic strategies like militarism or mercantilism, affecting vassal development, taxation, and diplomatic stance. Regional trade routes allow economic expansion and interaction with neighboring provinces, adding layers of depth to the economic simulation. Famous historical events such as the Honnoji Incident, Battle of Kawanakajima, and Battle of Sekigahara are presented with full voice acting and illustrated cutscenes, adding rich context and character development.

Gameplay mechanics are designed for both gamepad and touchscreen control, allowing fluid navigation of maps, units, and policies across both PS5 and Switch 2. The battle system remains true to the series’ roots, focusing on real-time command on an overworld map. The improved Battlefield system allows tactical troop deployment and formation control on specific historic battlefields like Nagashino or Komaki-Nagakute, enhancing strategic flexibility. Weather, terrain, and morale factors further enrich combat depth, requiring both tactical planning and historical understanding.

Graphically, the PS5 version supports 4K resolution and high frame rates, with highly detailed terrain, towns, and character illustrations blending traditional and modern styles. The Switch 2 version retains impressive fluidity and portability, making it ideal for long-form simulation gameplay. The audio design includes traditional Japanese music and period-accurate voice acting. All story cutscenes feature voiceovers and hand-drawn art, enhancing the immersive historical atmosphere.

Upon its original release, Rebirth received strong reviews from both players and critics. The autonomous vassal feature was particularly praised for improving mid-to-late-game pacing, reducing micromanagement, and adding replayability through emergent scenarios. The Power-Up Kit deepened the strategic experience and brought richer historical fidelity, leading many to regard it as the most "authentic Sengoku simulation" in the franchise’s history. It earned high ratings on platforms like Amazon Japan and Gamer.ne.jp and ranked among the top-selling strategy titles on both PS5 and Switch in Japan. While some users noted that AI behavior could still be improved, the game’s overall completeness and depth were widely recognized.

In conclusion, Nobunaga’s Ambition: Rebirth with Power-Up Kit Complete Edition is not only Koei Tecmo’s most comprehensive take on Sengoku-era simulation, but also a must-play for veterans of the series and fans of historical strategy alike. It maintains the traditional depth the series is known for while incorporating modern conveniences, intelligent systems, and immersive storytelling. It offers players the chance to relive the age of warring states not merely as observers, but as active participants shaping the rise and fall of Japan’s greatest warlords.
