《恐怖驚魂夜×3 三日月島事件的真相》（日文原名：かまいたちの夜×3 三日月島事件の真相）是經典音響小說系列《恐怖驚魂夜》的最終章，最早於 2006 年在 PlayStation 2 平台推出，由Spike Chunsoft（前身 Chunsoft）開發。2024 年則推出整合三部曲主線劇情的移植版本，登上 Steam、PlayStation 4 與 Nintendo Switch，讓新玩家能一次完整體驗這個橫跨數代的推理經典。

延續前作事件，時間設定在「監獄島」篇的一年後。曾經的倖存者們為了悼念逝去的同伴，再次聚集於三日月島。然而，原以為已經結束的詛咒卻再度復甦，島上很快發生新的連環殺人事件，氣氛從一開始的哀悼迅速轉為緊張與不安。故事不再侷限於單一主角，而是透過矢島透、香山誠一、俊夫與啟子四名角色的視角交錯推進。這種多重敘事讓玩家能從不同立場拼湊事件全貌，也使整體懸疑感層層堆疊。

系統方面最大的特色在於「Zapping」多視角切換機制。在時間軸上以約五分鐘為單位自由切換角色視點，不同角色的行動與選擇會互相影響彼此的命運與劇情發展。某個看似不起眼的決定，可能在另一個角色的時間線中引發重大後果，因此需要反覆觀察與推理，逐步拼出完整真相。遊戲同時提供時間軸整理功能，讓各角色在不同時間點的行動一目了然，減少理解上的混亂。

2024 年的移植版除了收錄本作之外，也整合了系列前兩部的重要篇章，使整體敘事更加完整，從雪山山莊事件一路延伸至監獄島與三日月島，形成一條連貫的主線。這樣的編排不僅方便新玩家入門，也讓老玩家能重新檢視伏筆與細節，體驗更完整的故事結構。

在市場評價方面，普遍獲得高度肯定，特別是結局揭露真相時的衝擊力，被認為極具我孫子武丸式風格，充滿出乎意料的反轉與心理層面的震撼。同時，多視角系統也被視為提升推理深度的重要設計。不過也有部分聲音指出，相較於前作，劇本份量略顯精簡，加上頻繁切換視點可能讓節奏顯得稍微拖沓。

整體而言，本作更像是一部為系列收尾的總結篇，將前兩代留下的謎團加以補完，並為整個《恐怖驚魂夜》系列畫下一個具有情感與衝擊力的句點。對於喜歡懸疑推理與文本敘事的玩家而言，這不僅是一款遊戲，更是一段完整且值得細細品味的故事體驗。

Kamaitachi no Yoru ×3: The Truth of the Mikazuki Island Incident (Japanese: かまいたちの夜×3 三日月島事件の真相) serves as the final chapter of the classic sound novel series Kamaitachi no Yoru. Originally released in 2006 for the PlayStation 2 and developed by Spike Chunsoft (formerly Chunsoft), the title later received a remastered collection in 2024 that compiles the main storylines of the entire trilogy. This updated version launched on Steam, PlayStation 4, and Nintendo Switch, allowing new players to experience the full narrative arc of this long-running mystery series in one complete package.

Set one year after the events of the “Prison Island” arc, the story follows the surviving characters as they reunite on Mikazuki Island to mourn those who lost their lives. However, what was thought to be a concluded curse resurfaces, and a new سلسلة of murders soon unfolds. The atmosphere quickly shifts from quiet remembrance to mounting tension and unease. Unlike earlier entries, the narrative is no longer confined to a single protagonist. Instead, the story unfolds through the interwoven perspectives of four characters—Toru Yajima, Seiichi Kayama, Toshio, and Keiko. This multi-perspective structure allows players to piece together the truth from different angles, gradually building layers of suspense and complexity.

The most distinctive gameplay feature is the “Zapping” system, which enables players to switch between character viewpoints along a timeline in roughly five-minute increments. Each character’s decisions and actions can influence the fate of others and alter the course of events. Seemingly minor choices may lead to significant consequences in another character’s timeline, encouraging careful observation and deduction. To support this system, the game includes a timeline interface that clearly organizes each character’s movements and progress, helping players keep track of the unfolding narrative without confusion.

The 2024 remastered version not only includes this final chapter but also integrates key story arcs from the first two titles, creating a seamless narrative that spans from the mountain lodge incident to Prison Island and finally Mikazuki Island. This structure makes it easier for newcomers to follow the story while giving longtime fans the opportunity to revisit foreshadowing and narrative details with greater clarity.

In terms of reception, the game has been widely praised, particularly for the impact of its final revelation. The conclusion is often described as embodying the signature style of novelist Takemaru Abiko, delivering unexpected twists and strong psychological intensity. The multi-perspective system has also been recognized for enhancing the depth of deduction. However, some criticism has been directed at the relatively shorter script compared to previous entries, as well as the pacing, which can feel slightly sluggish due to frequent perspective switching.

Overall, this title functions as a definitive conclusion to the series, tying together unresolved plot threads from earlier installments and delivering a finale that is both emotionally resonant and dramatically impactful. For players who appreciate suspenseful storytelling and text-driven narratives, it stands not merely as a game, but as a complete and deeply engaging narrative experience worth savoring.
