About Cthulhu: The Cosmic Abyss
Cthulhu: The Cosmic Abyss sends you deep into the sunken city of R'lyeh as an occult investigator unraveling a cosmic mystery while battling encroaching madness and cosmic horrors in this Lovecraftian thriller. Your choices, detective work, and sanity management shape the branching narrative as you uncover reality-shattering secrets hidden within nightmarish, physics-defying environments.
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.

What Steam players say
Recent verbatim reviews from Steam — separate from playze.io community reviews below.
The premise was promising but the game is buggy as hell. What really did it for me was constant bug of not being able to continue once in the capsule. It just sits there. Also, who devised the auto save system?? Totally pointless. Even though I bought this in the sale, I refunded it. In It's current state I would give this game a wide berth.9 found this helpful
pretty game with broken controls, controller controls break all the time, keyboard controls are broken.. games unplayable.. but you won't realize that till your more then 2 hrs in and can't refund it.. buyer beware.. game shouldn't be allowed to be sold in this state..what a rip off 1/104 found this helpful
I like this game, and I despise this games state. You have seen the other reviews, I went into it with an open mind and a willingness to deal with bugs. This game tested my patience. I found myself reloading or quitting to menu (this is probably the easiest way to deal with the cannot use a button issue) at a minimum of every 15 minutes. Sometimes I would need to do this multiple times in a single section to analyse clues. If you enjoy Lovecraft, the story is worth seeing, I just cannot recommend it be worth playing. Buy is a discount if you want to try it, but don't go into this thinking you will have an easy ride3 found this helpful
tons of bugs2 found this helpful
Good atmosphere but overall a bad game. Too heavy on the detective work and too light on the Lovecraftian horror that it should have. I appear to have been like many others who couldn't even complete the game because of bugs (for me a critical deduction didn't appear in chapter 6) and by that point I had certainly tried hard enough.2 found this helpful
I really tried my best to keep playing, but unfortunately, the game is so full of bugs that it's become impossible to progress. The latest bug completely prevented me from moving forward (when I enter the capsule), and other players have reported the same issue. I really hope the developers fix these issues. I'll give the game another try in a few months. It's a shame because the game has a lot of potential and looks great visually.
