《超新時空遊戲海王星∞》（日文原名：超新時空ゲイム ネプテューヌ∞）是由Compile Heart開發的角色扮演遊戲，亦是「海王星系列」睽違多年推出的正統續作。作品於2026年3月19日正式發表，預定於8月27日登上PlayStation 5、Nintendo Switch等平台。作為系列久違的編號新作，本作在系統與規模上皆大幅進化，試圖打造一個更具動態與臨場感的次世代「遊戲業界」世界觀。

在基本設定與劇情方面，以「世界終末」為核心主題展開。一顆象徵毀滅的隕石墜落，為整個世界揭開崩壞的序幕。在萬物走向絕望之際，唯有女神妮普禔努被留在一個神祕的純白空間之中。她在不明聲音的引導下，獲得能夠「重來」的力量，臉上浮現的神祕數字象徵著命運的倒數與循環。隨著一次次的失敗與重啟，時間在「終結」與「開始」之間不斷輪迴。玩家將跟隨妮普禔努與夥伴們，在不斷重構的世界線中結識新的同伴與敵人，逐步逼近真正的末日真相。除了系列熟悉的女神角色如諾瓦露、布蘭與貝兒外，本作亦加入多位全新守護女神，包括性格偏執的宅系女神露潔、講求效率至上的天才女神希艾露，以及以雙人一體形式登場的安娜與羅特，讓整體劇情更加多層次且充滿變數。

在操作與遊戲系統上，導入系列少見的「空中探索」機制。可以透過簡單直覺的操作，在廣闊空域中自由飛行，並直接在空中進行戰鬥與探索。這不僅讓關卡設計從平面延伸至立體空間，也帶來更多樣化的敵人與機關配置。戰鬥系統方面，角色可即時切換女神化形態，在高速移動與技能輸出之間取得平衡，強調節奏感與操作流暢度。此外，本作新增「終末戰鬥」系統，讓多達11位女神同時參戰，對抗擁有壓倒性力量的超大型Boss。每位女神皆擁有一次專屬的「終末反制技能」，需在關鍵時機發動，以抵禦敵方的毀滅性攻擊。整體玩法從過去偏重指令式戰鬥，轉變為更具動作性與策略深度的混合型系統。

在市場評價與玩家期待方面，自發表以來便受到系列粉絲高度關注。評論普遍認為，在視覺表現與遊戲規模上的提升相當明顯，特別是空中探索與大規模團戰機制，被視為系列邁向新世代的重要突破。同時，新角色的加入與多線敘事也為劇情帶來更多新鮮感。不過，也有部分玩家持觀望態度，認為過往系列在節奏與系統深度上的問題仍需進一步優化。整體而言，本作被視為一次兼具「革新」與「傳承」的嘗試，不僅延續系列一貫的幽默與自我吐槽風格，也試圖以更宏大的敘事與玩法，重新定義海王星系列在現代RPG市場中的定位。

Hyperdimension Neptunia ∞ (Japanese title: Choujigen Game Neptune ∞) is a role-playing game developed by Compile Heart, and serves as a long-awaited mainline entry in the Hyperdimension Neptunia series. Officially announced on March 19, 2026, the game is scheduled for release on August 27 for platforms including PlayStation 5 and Nintendo Switch. As a numbered sequel arriving after many years, this title significantly expands both the scale and systems of the series, aiming to deliver a more dynamic and immersive “Gamindustri” experience for modern hardware.

In terms of its setting and narrative, the game revolves around the theme of an impending apocalypse. A catastrophic meteor signals the beginning of the world’s collapse, plunging everything into despair. Amid this destruction, Neptune is the only goddess left within a mysterious white void. Guided by an unknown voice, she gains the power to “retry,” with a cryptic number appearing on her cheek as a mark of fate and cyclical time. As failure and reset repeat endlessly, the story unfolds across looping timelines where “endings” and “beginnings” blur together. Players accompany Neptune and her allies as they encounter new companions and enemies, gradually uncovering the truth behind the world’s destruction. Alongside familiar characters such as Noire, Blanc, and Vert, several new goddesses are introduced, including the obsessive shut-in Rouge, the efficiency-driven genius Ciel, and the unique duo Anna and Lot, who combine into a single goddess form. These additions deepen the narrative and add further complexity to the evolving storyline.

Regarding gameplay and systems, Hyperdimension Neptunia ∞ introduces a new “aerial exploration” mechanic, a first for the series. Players can freely traverse vast skies with intuitive controls, engaging in both exploration and combat mid-air. This evolution transforms level design from flat environments into fully three-dimensional spaces filled with airborne enemies and environmental mechanics. The combat system has also been enhanced, allowing real-time transitions into goddess forms, emphasizing speed, fluidity, and tactical adaptability. A major new feature, the “Endgame Battle” system, enables up to eleven goddesses to participate simultaneously in large-scale encounters against colossal bosses. Each goddess possesses a unique “End Counter Skill,” which can be used once at a critical moment to counter devastating enemy attacks. Overall, the gameplay shifts from the series’ traditional command-based structure toward a hybrid model that blends action and strategy.

In terms of market reception and anticipation, Hyperdimension Neptunia ∞ has attracted significant attention from longtime fans since its announcement. Early impressions highlight noticeable improvements in visual fidelity and game scale, with particular praise directed at the aerial mechanics and large-scale battle systems, which are seen as key innovations for the franchise. The introduction of new characters and expanded narrative paths has also been well received for adding freshness and depth. However, some players remain cautiously optimistic, noting that previous entries struggled with pacing and system refinement, and hoping these issues will be addressed. Overall, the game is widely regarded as an ambitious attempt to balance “innovation” and “tradition,” preserving the series’ signature humor and meta-commentary while redefining its place in the modern RPG landscape.
