故事講述高中生陣場湊，因祖母病危而回到已故母親的故鄉——一之瀨村。從陣場湊搭乘巴士行經鄉村道路的場景展開，黃昏染紅的天色與遠方山脈的陰影形成強烈對比，一開始就感受到不安與孤寂。隨著探索深入，陣場湊逐漸發現村莊背後隱藏的秘密，並揭開與蠶與繭相關的恐怖傳說。特別設定人類馴化不會飛的蠶作為故事核心象徵，編織出奇異且詭譎的敘事脈絡，從環境、居民互動到村莊的歷史，都充滿令人毛骨悚然的細節。

操作上，採用第一人稱視角，需在村莊中自由探索，觀察環境、解開謎題與收集線索。強調心理恐怖而非單純的驚嚇，透過光影、音效與細微的環境變化營造壓迫感。需要仔細觀察每個角落，理解線索之間的關聯，並透過探索揭露事件真相。試玩版中，部分授權音樂曾被靜音，但完整版已移除此限制，並新增電視節目字幕以便海外玩家理解劇情背景與文化細節。此外，遊戲的節奏偏慢，但設計細膩，玩家在探索過程中會逐漸感受到恐怖氛圍的累積與心理壓力。

整體而言，《空洞之繭》不僅是恐怖冒險遊戲，更是心理探索之旅。以第一人稱視角，深入偏遠村落，逐步揭開蠶與繭背後的神秘與恐怖。憑藉細膩的環境設計、沉浸式敘事以及心理恐怖的呈現，本作為喜愛深度探索、氛圍恐怖與懸疑故事的玩家提供充滿張力與沉浸感的遊戲體驗。

Hollow Cocoon is a first-person horror adventure game developed by the Japanese two-person team NAYUTA STUDIO. It was first released on PC on December 7, 2023, with a remastered version set to launch on Nintendo Switch on December 17, 2025. Set in rural Japan during the 1980s, the game recreates a nostalgic yet unsettling atmosphere. Through meticulously crafted environments, dynamic lighting, and immersive sound design, players are drawn into a world of hidden, indescribable terror.

The story follows high school student Minato Jinba, who returns to his late mother’s hometown, Ichinose Village, after learning that his grandmother has fallen gravely ill. The game begins with a bus ride along winding country roads, where the red hues of dusk clash with the dark silhouettes of distant mountains, immediately instilling a sense of unease and loneliness. As Minato delves deeper into the village, he uncovers its sinister secrets and unravels chilling legends connected to silkworms and cocoons. The silkworm—domesticated and incapable of flight—serves as a symbolic centerpiece of the narrative, weaving together a bizarre and haunting storyline. From the village’s environment and history to its interactions with residents, every detail contributes to an atmosphere steeped in dread.

Gameplay is presented from a first-person perspective, requiring players to freely explore the village, examine surroundings, solve puzzles, and collect clues. The game emphasizes psychological horror over cheap jump scares, using lighting, sound, and subtle environmental changes to generate an oppressive atmosphere. Careful observation is essential, as players must piece together connections between clues to reveal the truth behind the village’s mysteries. While the demo had certain licensed tracks muted, the full version removes this restriction and even includes subtitled TV program segments to help overseas players better understand the cultural and narrative context. The pacing is deliberately slow, designed to allow tension to gradually build, heightening psychological pressure as players progress.

In terms of reception, Hollow Cocoon has attracted significant attention within the horror adventure community thanks to its unique rural horror setting and carefully layered storytelling. Players widely praised its faithful recreation of 1980s Japanese countryside landscapes and its nuanced approach to psychological terror. While the game avoids relying on frequent jump scares, its methodical buildup of fear through environment and narrative keeps players in a constant state of tension. On the other hand, its slower, exploration-heavy gameplay may feel unfamiliar to those who prefer fast-paced, action-oriented horror titles—but this pacing is also key to its immersive experience.

Overall, Hollow Cocoon is more than just a horror adventure—it is a journey into the human psyche. Through its first-person perspective, players descend into the eerie depths of a remote village, gradually uncovering the mysteries and horrors tied to silkworms and cocoons. With its atmospheric environments, immersive storytelling, and focus on psychological fear, the game offers a gripping and deeply immersive experience for fans of exploration-driven, atmospheric, and suspenseful horror.
