《永恆迴響：零號病人》（Eternity's Echo: Patient Zero）是由Demonsoft Games開發的第一人稱動作生存恐怖遊戲，於2025年第四季度登陸PC（Steam）平台。以強烈的沉浸式氛圍、緊湊的劇情推進與靈活的玩法設計，帶領玩家進入融合科幻、恐怖與解謎要素的異世界冒險。

主角是「維度調查局」（Dimensional Investigations Bureau, D.I.B.）的探員——雷恩・威廉姆斯（Raine Williams）。任務開始於美國亞利桑那州偏遠地區的溫納鎮，一座看似荒廢卻暗藏詭異氣息的加油站。在這個被異次元力量吞噬的場所，現實逐漸崩解，時間與空間出現錯亂，需一步步拼湊真相，揭開「零號病人」與這場異象背後的秘密。

遊戲機制極具多樣性。不僅要面對異界怪物的威脅，還需在詭譎不安的場景中進行解謎與探索。融合高強度的跑酷元素與生存戰鬥，在逃避追擊與壓力感中保持高度警覺。場景設計方面，開發團隊強調異空間的動態變化與高自由度的互動機制，許多關卡具有多條通關路線，鼓勵玩家根據自己的策略與直覺進行選擇。

除驚悚的視覺風格與音效設計，敘事方式也採取非線性結構，透過日誌、錄音、影像與現場殘留線索交織出完整劇情，必須主動探索與思考，逐步拼湊出整個事件的真相。這樣的敘事安排也大幅提升遊戲的重玩價值與沉浸感。

目前尚未正式推出，但預告釋出後在遊戲社群中已引發不少關注。許多玩家對其融合解謎與跑酷的設計表現出高度興趣，認為其設定類似《控制》（Control）與《傳送門》（Portal）的異世界感與謎團感結合，帶來新穎又令人期待的體驗。不過，也有評論指出，恐怖遊戲市場競爭激烈，要在眾多作品中脫穎而出，仍需更深度的劇情與創新玩法加持。

總體而言，《永恆迴響：零號病人》是融合多重遊戲元素的恐怖生存新作，透過異次元世界與心理驚悚元素打造出獨特氛圍，對喜愛解謎、探索與劇情導向玩法的玩家而言，無疑是值得期待的潛力作品。

Eternity's Echo: Patient Zero is a first-person action survival horror game developed by Demonsoft Games, scheduled for release on PC (via Steam) in the fourth quarter of 2025. With its immersive atmosphere, tightly woven narrative, and flexible gameplay design, the game draws players into an otherworldly adventure blending science fiction, horror, and puzzle-solving elements.

The protagonist is Raine Williams, an agent of the Dimensional Investigations Bureau (D.I.B.). The mission begins in the remote town of Winner, Arizona, at an apparently abandoned gas station that harbors an unsettling and eerie presence. As the environment is slowly consumed by interdimensional forces, reality starts to unravel. Time and space become distorted, and players must piece together clues to uncover the truth behind the "Patient Zero" and the supernatural events unfolding around them.

The gameplay mechanics are notably diverse. Players face not only threats from otherworldly creatures but also must navigate mysterious, unstable environments filled with puzzles and cryptic details. High-intensity parkour mechanics are integrated with combat and survival elements, demanding players remain alert while escaping danger and navigating under pressure. The level design emphasizes dynamic, ever-shifting dimensions and high degrees of environmental interactivity, offering multiple paths and solutions that encourage strategic and intuitive exploration.

In addition to its chilling visual style and immersive sound design, the narrative follows a non-linear structure. The story unfolds through scattered logs, recordings, video footage, and environmental clues, challenging players to actively investigate and piece together the fragmented history. This storytelling approach not only enhances immersion but also adds significant replay value.

Although the game has not yet been officially released, its teaser trailer has already sparked considerable interest within gaming communities. Many players are intrigued by the blend of puzzles and parkour, comparing its surreal atmosphere and enigmatic narrative style to titles like Control and Portal. There’s growing excitement around the game’s potential to offer a fresh and engaging experience. However, some critics caution that the horror genre remains fiercely competitive and suggest that Eternity's Echo will need a deeper story and truly innovative mechanics to stand out.

Overall, Eternity's Echo: Patient Zero is shaping up to be a promising survival horror title that merges multiple gameplay elements to create a distinct and eerie atmosphere. For fans of narrative-driven experiences rich in puzzles, exploration, and psychological tension, this could be one of the most anticipated indie releases on the horizon.
