《屍體派對 Tetralogy Pack》（日文名：コープスパーティー TETRALOGY PACK）是集結四部經典恐怖冒險遊戲的合集作品，於2025年8月7日在 Nintendo Switch平台推出。這部合輯內含《Corpse Party BloodCovered：Repeated Fear》（2021重製版）、《Corpse Party: Book of Shadows》、《Corpse Party: Sweet Sachiko’s Hysteric Birthday 2U》以及《Corpse Party: Blood Drive》四款完整遊戲。除標準版外，限定版還附贈OVA 動畫《Tortured Souls》的Blu-ray光碟與原聲配樂，無論對系列老粉或新玩家都是一次極具收藏價值的完整體驗。

本系列最初於1996年誕生，自RPG Maker Dante98遊戲引擎製作起便以獨特的「像素恐怖」風格聞名，並藉由2008年的重製與後續多平台移植建立起長壽口碑。《Corpse Party BloodCovered：Repeated Fear》初代作品的劇情設定在詭異的「天神小學」，一群高中生因進行「幸福的幸子」儀式失敗，被捲入異次元空間。他們在這座靈異校舍中不斷遭遇鬼魂騷擾與死亡威脅，需靠觀察與解謎，解開角色背景與場景秘密，進而逃出生天。隨著劇情進展，會有多重結局與犧牲，主線格外沉重且帶有心理驚悚色彩。

續作《Book of Shadows》採用類似視覺小說與探索結合的模式，延續前作角色視角，以更多劇情與回溯段落補足第一部的空白與謎團，收錄七個章節介與過去與未來交錯的恐怖故事，初版在PSP主機上市。《Sweet Sachiko’s Hysteric Birthday 2U》則風格一轉，以搞笑與惡搞為主軸，作為外傳休閒小品存在，故事以幸子生日所開始的喜劇文化季所展開。《Blood Drive》則是本系列少見的3D表現作品，採第三人稱俯視視角，加入手電筒、道具探索與逐步揭露的家族血脈故事，使整體世界觀更為黑暗並帶有Lovecraft式神秘色彩。是系列的最終章，舞台設定在最開始的詛咒學校，女主角步美將作出最終決定。

在操作設計上，四部作品大多以解謎與事件觸發為核心，並沒有傳統意義上的戰鬥系統。需於各式場景中尋找道具、解鎖機關，並根據選擇進入不同的劇情線與結局。《Blood Drive》是少數加入潛行、躲避系統的作品，但對於手感與難度的掌握仍有些微爭議。此外，系列設計中大量使用「錯誤結局」（Wrong Endings）作為反饋機制，一旦操作失誤或錯誤選擇，角色便會以極為殘酷的方式死亡，這也正是《屍體派對》最受推崇與最具爭議的特色之一。

就市場評價而言，《Corpse Party BloodCovered：Repeated Fear》重製版在Nintendo Switch上獲得中上水準的正面回應。許多玩家讚賞其劇情深度、角色刻畫與經典恐怖音效的運用，尤其在語系本地化（繁中、簡中、英語）上表現良好，成功吸引到非日語玩家。然而，《Blood Drive》與《Sachiko 生日篇》則評價較為兩極，有玩家認為節奏過慢、風格偏離本傳核心，且技術實現上表現略顯粗糙。

綜合來看，《屍體派對 Tetralogy Pack》是極具懷舊情懷與心理驚悚張力的恐怖遊戲合集。它不僅保留系列從像素恐怖起家的獨特氣質，也嘗試在視覺與劇情上推陳出新。雖然操作設計與遊戲引導存在些許門檻，但對於喜歡故事導向、喜愛恐怖敘事與分支劇情體驗的玩家來說，這無疑是橫跨十年的驚悚巡禮，值得深入體驗與收藏。

Corpse Party Tetralogy Pack (Japanese title: コープスパーティー TETRALOGY PACK) is a compilation of four classic horror adventure games, launching on Nintendo Switch on August 7, 2025. This collection includes full versions of Corpse Party BloodCovered: Repeated Fear (2021 remake), Corpse Party: Book of Shadows, Corpse Party: Sweet Sachiko’s Hysteric Birthday 2U, and Corpse Party: Blood Drive. In addition to the standard edition, a limited edition will be available, featuring a Blu-ray disc of the OVA anime Tortured Souls and the original soundtrack. For both longtime fans and newcomers, it offers a highly collectible and complete experience.

The Corpse Party series began in 1996 and gained attention for its unique “pixelated horror” style, created using the RPG Maker Dante98 engine. The series built a lasting reputation through its 2008 remake and later multi-platform ports. The first title, Corpse Party BloodCovered: Repeated Fear, is set in the eerie Heavenly Host Elementary School. After a failed “Sachiko Ever After” charm, a group of high school students is transported to an alternate dimension. Trapped in this haunted school, they must face tormented spirits, unravel the mysteries of the environment, and uncover each character’s backstory through exploration and puzzle-solving—all while struggling to survive. The narrative grows increasingly intense, featuring multiple endings and inevitable sacrifices, and is known for its deeply psychological horror tone.

The sequel, Book of Shadows, blends visual novel elements with point-and-click exploration. It continues the story from multiple characters’ perspectives, filling in gaps and expanding on the mysteries left unresolved in the first game. With seven chapters, it tells intertwining horror stories set in both past and future timelines. Originally released on the PSP, it deepened the emotional and narrative complexity of the series.

On a lighter note, Sweet Sachiko’s Hysteric Birthday 2U shifts genres entirely. This side story serves as a humorous and parody-driven spin-off, set during a bizarre birthday festival organized by the infamous Sachiko. While non-canonical, it features comedic scenarios and exaggerated character interactions, functioning as a lighthearted detour from the series’ usual intensity.

Blood Drive, the final chapter of the main storyline, introduces a 3D top-down perspective—a rarity in the series. It incorporates elements such as flashlight mechanics, environmental exploration, and stealth segments. The plot dives into a darker, more expansive mythos, weaving in family curses and Lovecraftian themes. The story returns to the cursed school from the first game, where protagonist Ayumi must face the consequences of the past and make her final choice.

In terms of gameplay, all four titles primarily emphasize exploration, puzzle-solving, and event-triggered story progression, rather than traditional combat. Players search environments for items, unlock paths, and make critical decisions that influence branching storylines and multiple endings. Blood Drive is one of the few entries to introduce stealth and hiding mechanics, though some players found its controls and difficulty balance uneven. A defining element of the series is its use of “Wrong Endings”—gruesome, often disturbing bad endings triggered by wrong moves or poor decisions. These brutal consequences have become both a trademark and a point of controversy within the Corpse Party franchise.

Reception-wise, Corpse Party BloodCovered: Repeated Fear received generally favorable reviews on Nintendo Switch. Players praised its compelling narrative, strong character development, and effective use of classic horror sound design. The game’s localization—offered in Traditional Chinese, Simplified Chinese, and English—was also well-received, helping to attract a wider, non-Japanese audience. However, Blood Drive and Sweet Sachiko’s Hysteric Birthday 2U received more mixed reactions. Some players criticized their slower pacing, tonal shifts away from the main series, and technical roughness in execution.

All things considered, Corpse Party Tetralogy Pack is a nostalgic and psychologically intense horror game collection. It preserves the franchise’s unique pixel-horror roots while attempting bold new steps in presentation and storytelling. Though there are some accessibility hurdles in gameplay design and progression, for players who enjoy story-driven experiences, horror narratives, and branching outcomes, this collection offers a gripping journey through a decade of fear—one well worth exploring and owning.
