About Cthulhu: The Cosmic Abyss
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.

Controls randomly stopped working? actions and cutscenes sometimes weren't in sync. only managed to play the game for 3 hours and the character stopped walking and interacting.9 found this helpful
Atmosphere top notch. But the gameplay is just baaaaad. Just watch the story on YT!! Movement and interaction with environment is annoying and sluggish. Puzzles are nonsense and not thought through. And the investigation/deduction mechanic is simply so annoying stupid that i can't force myself to play it any further.5 found this helpful
Alright. Let's break it down! This game is very Nancy Drew. Lot's of exploration, clue deducing, clue connecting, with very little threats. Now I want to preface that there are threats within a few of the chapters but they are few and far between, and if you take your time and pay attention most of those threats can be avoided. This game gives you heavy lore, lots of beautiful imagery, ambiance, and atmosphere. I wish it had more threats, more moments that actually validated the angst that the scenes set, however that's a personal preference. If you're looking for a horror game that doesn't have the classic chase scenes, fights, jump scares, or even the classic "Bad Guy" then this game is for you. Spoiler: you got a few different endings, and some great hidden mental "fu**ery". This game is more about fighting yourself than a threat, and what I mean is that this game gives you a lot of moments where you don't want to do that's needed, or what the game wants you to. So take this review with a grain of salt. In recommend it, though it's not something I would traditionally play. It's not your classic horror game, but great if you wanna experience heavy lore, deduce clues, and inves…2 found this helpful
if you like games with cryptic stories that you have to figure out piece by piece - its for you1 found this helpful
I really like this game. You just have to accept that this is not an action game, but an investigation/puzzle game. They captured the mythos very well. Normally, I would say it is not good for lovecraftian horror to get so much into detail, but this game managed that by portraying R'lyeh disturbing as it should be. On top of that, there were many times I really got scared just by investigating the environment. The AI named "Key" is much less annoying than I initially thought. So, if you like horror and thinking that game is for you.1 found this helpful
Some of these puzzles are damn hard to figure out, and there's a lot you can miss if you aren't looking around carefully. This does not diminish it's playability, it's a great seek and find without combat
