Your descent into madness has only just begun. With Cthulhu: The Cosmic Abyss - R'lyeh Edition, horror reaches new dimensions. Enhance your experience with the following exclusive content:

  • The Shining Trapezohedron side quest: search for fragments of the shining trapezohedron and learn more about this ancient artefact through puzzles that will test your perception and your sanity. As a reward, unlock an exclusive evolution that gets better as you put the artefact back together. Also, discover an exclusive hand skin imbued with the red stone, which reacts every time you approach a fragment.
  • An official scenario for the Arkham Horror role-playing game: extend the adventure with a full, exclusive scenario entitled "Descent". Designed for the popular Arkham Horror tabletop role-playing game, you and your friends can play as new Ancile investigators facing an occult threat directly linked to the game's universe.
  • The Art Pack: capture your descent into madness with this exclusive digital pack, containing the non-Euclidean artbook and the supernatural soundtrack.

2053: Across the globe, the occult threat grows ever more blatant, and strange, incomprehensible events multiply. As the Earth's surface resources dwindle, powerful corporations turn to the uncharted depths of the oceans, unaware of the ancient horror they are about to awaken.

In this tense Lovecraftian thriller, you play Noah, tasked with investigating the mysterious disappearance of miners in the depths of the Pacific Ocean. With the help of your AI companion, Key, explore the vast, labyrinthine prison of R'lyeh—an ancient, sunken city of cyclopean proportions—and resist the creeping madness caused by Cthulhu's influence. At its core lies a secret that could shatter your understanding of reality.

REVEAL THE UNSPEAKABLE
Face nightmares and cosmic abominations that will push your sanity to its limits. Journey through a futuristic reinterpretation of Lovecraft's mythos and uncover the legendary sunken city of R'lyeh. But beware: the deeper you descend, the more your mind succumbs to Cthulhu's relentless influence.

CHALLENGE THE BOUNDARIES OF YOUR MIND
Dive into the darkness with Key, your AI companion. Follow leads, gather scattered clues, and sharpen your detective skills to solve immersive and complex puzzles. Uncover hidden truths and look beyond appearances to choose your path to resolving the case. Every mystery offers branching routes and secret passages waiting to be discovered.

AN UNFORGETTABLE NARRATIVE EXPERIENCE
As an agent of Ancile, a secret division of Interpol specializing in occult affairs, you are thrust into a gripping story with complex characters, brought to life through cinematic storytelling. Immerse yourself in a first-person investigative horror adventure with a rich, branching narrative, where your choices and understanding will shape Noah’s fate in this nightmarish world.

Powered by Unreal Engine 5, Cthulhu: The Cosmic Abyss features mind-bending environments that defy the laws of physics, pushing the boundaries of immersive storytelling to new heights.

Critics Read more: Opencritic.com

"Cthulhu: The Cosmic Abyss can't find anything interesting or new to say about Lovecraft's work, but its detective adventure gameplay is an extremely promising foundation."

"Ultimately, the game did make me lose my sanity, but not always for the reasons I expected. While the atmosphere is great, the lack of technical polish in the latter half of the game..."
