The abyss is calling… and it knows your name

Nacon and Big Bad Wolf are beyond proud and excited to finally share their work with players around the world. Cthulhu: The Cosmic Abyss is now available on Steam!

A word from Big Bad Wolf's team

What a long way we've come since that completely crazy pitch that took us on a 3-year journey... We often hear that releasing a game is a miracle, and this principle was confirmed once again with this project.

Indeed, as is often the case, the last few months of production were not the easiest for the studio. The difficulties were not without their impact on us, but that didn't stop us from giving our all.

We want to particularly thank our team for their flexibility and motivation, as well as everyone who continued to support us on the project. We are very proud of what we have accomplished together!

Now the time has finally come to pass the controller to you! It's your turn to embody Noah, detective of the occult, and dare to descend into the depths

Take on the role of Noah, an agent sent to investigate the mysterious Ocean-I underwater station. But this is no ordinary mission. It is a descent into a world that defies logic, a journey to the heart of an ancient mystery where every clue threatens to unravel your sanity.

• Explore the depths of a submerged facility hiding unspeakable secrets

• Investigate, analyze, and reconstruct the truth using your tools and your mind

• Face psychological horrors that will challenge your perception of reality

• Make choices that will shape Noah’s fate and lead to multiple endings

In R'lyeh, all dreams end.

There are no weapons. No easy answers. Only your instincts… and the creeping presence lurking in the dark. As you descend deeper into the abyss, your mind will be tested. Hallucinations, distortions, and impossible visions will blur the line between reality and madness.

Buy the game now and get the exclusive content "Sanity Pack", available until April 30th. Don’t wait until it sinks into the depths.

Will you uncover the truth… or lose yourself to it?

If you are not afraid of what lies beneath, you can dive deeper with the R’lyeh Edition. The R’lyeh Edition includes:

• The full game

• Eldritch Soundtrack

• Non-Euclidrean Artbook

• The Shining Trapezohedron Side Quest

• Exclusive Arkham Horror TTRPG scenario

Every step you take brings you closer to the truth… and further away from reality. There is no turning back now. The gates of R’lyeh are opening.

Greetings Agents,

From the very first reveal, many of you have commented on the deep, unsettling atmosphere of Cthulhu: The Cosmic Abyss. A monumental part of creating that ever-present sense of dread and wonder is the game's soundtrack, and today, we want to take you behind the curtain to see how that soundscape was born.

We are incredibly honored to present a special interview with the two brilliant artists who collaborated on the game's magnificent score: our lead composer, Nicolas Garcia, and the world-renowned cellist, Tina Guo.

In this feature, they discuss their creative process, the unique challenges of translating cosmic horror into music, and how they worked together to build a soundtrack that is as beautiful as it is terrifying.

The music of the abyss is a core part of the experience, guiding your descent, fraying your nerves, and rewarding your discoveries. We feel privileged to have worked with such phenomenal talent to bring it to life, and we hope you enjoy this inside look at their craft.

Thank you for your continued support, and we'll see you in the deep.

Greetings agents,

I am now authorized to transmit your official mission briefing. It contains critical information regarding the operational mechanics you must master to ensure mission success and maintain system integrity.

Please assimilate the following data.

For your reference, I have compiled a tactical summary of your core systems:

• Primary Directive: You will investigate the station. Analyzing clues will consume your suit's limited Energy supply. I advise you to allocate this resource logically.

• The Vault: All validated data will be organized in this cognitive space. Here, you will connect evidence and formulate hypotheses. The truth construct will adapt based on your conclusions.

• Sonar System: Your primary tool for navigating low-visibility environments. The current NL5 calibration allows you to identify objectives and potential hazards.

• Suit Evolutions: You may find compatible technology to enhance your suit's performance. Be advised: system degradation is possible under certain environmental pressures.

• Corruption Protocol: Exposure to anomalous phenomena will result in Corruption. This systemic decay will impact your cognitive and physical functions. Sanity preservation is paramount.

Join the investigation on Reddit

The investigation is expanding. ANCILE has now established a new outpost for our community on Reddit! Join us at r/CthulhuTheCosmicAbyss to discuss your theories, share your expectations, and speak directly with the dev team.

We look forward to seeing you there. Stay vigilant.

Hey everyone,

We’re excited to share that the playable demo for Cthulhu: The Cosmic Abyss is now live as part of Steam Next Fest (February 23 – March 2).

This demo will be available for a limited time during the event. If you’ve been curious to experience the beginning of the investigation and explore the Ocean-I station for yourself, now’s the moment.

Demo is available right now:

What's in the demo?

This demo gives you access to the full first chapter and the beginning of the second!

From there, Noah descends into the abyss to do what he was sent for: investigating a chilling mystery, navigating a hostile environment, and confronting a horror that defies reality itself.

You’ll get to experience:

• Unraveling the first threads of the mystery, using your investigative tool, The Vault, to log every clue and piece together the fate of the missing crew.

• The claustrophobic descent into the abyss, where your only guide through the crushing dark is the ping of your Sonar, revealing the path forward and the secrets hidden within.

• Your first chilling encounter with the impossible, forcing you to monitor your Sanity System as the world begins to warp and the battle for your own mind begins.

It’s a substantial taste of the core mechanics, and the psychological depth we’re building into the full experience - just enough to pull you into the mystery, and maybe... just maybe... let you keep a grip on your sanity.

A fresh start for the full game

To ensure the most polished and terrifying experience on April 16th, your save from the demo will not carry over to the full game.

We're still making final tweaks and want everyone to begin their full journey with the definitive, day-one version of the game. This way, everyone starts their descent into madness together, right from the very beginning.

What lies in the full game beyond the demo?

The demo guides you through your first steps into the abyss: it’s designed to teach you the rules of survival, how to use your tools, and how to recognize the first signs of your mind fraying at the edges.

In the full game, those rules are pushed to their breaking point.

As you venture deeper through all chapters of the story, the investigative challenges will become far more intricate, demanding you combine every tool at your disposal under immense psychological pressure. The Sanity system, in particular, will evolve from a background threat into a central gameplay pillar, warping the world around you in terrifying and unpredictable ways.

Most importantly, your journey will culminate not in a single conclusion, but in one of several distinct endings. Every choice you make and how you manage your descent into madness will directly shape the final, horrifying truth you uncover on April 16th.

Thank you for your support

Bringing this demo to Steam Next Fest is an important moment for us. It’s the first time players can explore a portion of Cthulhu: The Cosmic Abyss directly, experience the investigation mechanics, and step into the Ocean-I station themselves.

Developing this project has been a long journey for the team, and seeing it in players’ hands - even in this limited format - means a great deal.

If you decide to try the demo, thank you. Every session played, every comment shared, and every wishlist added genuinely supports the final stretch of development.

We’re currently focused on final polish and refinements ahead of release. If you enjoy what you experience during Next Fest, make sure to wishlist the game to follow us through to launch:

The Ocean-I station is the first point of contact, still standing at the edge of the abyss: Its crew vanished, its systems continue to run, and whatever happened here never reached the surface.

This is where your next Lovecraftian investigation begins.

Greetings, Agent.

As your investigation progresses, information will accumulate quickly: observations, objects, fragments of dialogue, and research data. To help you manage this flow without dictating conclusions, I have granted you access to some information about the Vault.

The Vault is an investigative tool designed to record and organize clues gathered during exploration, interactions, research, and object handling. It allows you to review your findings, visualize your progress, and deepen your understanding of certain clues when further analysis is possible.

Some clues contain sub-elements. Others may unlock data that can later be used to refine tools such as the Sonar.

The Vault does not solve the investigation for you.

It never performs deductions in your place, nor does it provide ready-made solutions. You are free to organize, connect, and interpret clues as you see fit - but every conclusion must come from you.

When a situation requires resolution, the Vault will remain silent.

The final action will always be yours.

Proceed carefully, Agent.

Ancile is an international organization operating across multiple territories.

Public records are deliberately restricted. Official recognition is neither sought nor permitted: discretion is required for the safety of the population and the integrity of ongoing operations…

Unlike institutions such as Interpol, Ancile does not present itself as a unified global authority. Instead, it is described as a network - composed of autonomous cells, each operating within its own geographic and operational scope.

Primary fields of activity include:

• Investigation of anomalous phenomena

• Containment of unconventional threats

• Preservation of sensitive knowledge

Available data suggests Ancile does not function through a centralized command.

Operations are handled by independent “circles,” each maintaining its own resources, personnel, and protocols.

Information sharing between circles appears selective and conditional.

This decentralization reduces exposure and limits internal compromise.

Further structural data is restricted.

As you know, Ancile does not recruit publicly.

Individuals are identified, evaluated, and contacted through indirect channels - often without their awareness. Selection criteria vary by region and specialization.

Confirmed ranks include:

• Novice - field assistance under mentorship

• Initiate - autonomous operational role

• Mentor - oversight, evaluation, and strategic coordination

Advancement timelines are inconsistent.

Higher classifications exist but are not referenced in accessible records.

Certain Ancile circles reportedly employ advanced analytical systems, including experimental artificial intelligence designed to assist field agents.

Purpose:

• Cognitive stabilization

• Environmental analysis

• Threat interpretation

Integration methods remain undisclosed.

This record exceeds the scope of this transmission and was not intended for this format.

Certain experimental analysis protocols will be authorized following recurring anomalies that cannot be resolved through isolated review. Cross-analysis is advised, as multiple external correlations will be expected to surface among newly assigned personnel.

Further analysis will be relocated to persistent review channels at a later date.

Greetings, Agent.

Before we continue our descent, it is important to understand the world you are leaving behind.

The year is 2053, and despite what the old projections promised, you won’t find flying cars waiting on the surface.

Progress did not arrive in spectacle. It arrived in necessity.

A world that learned to adapt

By 2053, the crisis was no longer theoretical.

Surface resources dwindled. Supply chains fractured. Entire regions were forced to rethink how they survived.

The response was not collapse but adaptation: cities became denser, smarter, more efficient. Energy was rationed, optimized, monitored. Every system was designed to waste less, last longer, and compensate for what could no longer be extracted from the surface.

Technology as extension, not luxury

In this future, technology did not make life easier, it made it possible. It is is no longer something you carry but something you become.

Artificial intelligence supports decision-making, navigation, logistics, and survival - often silently, often invisibly.

Human limits are no longer accepted as fixed.

You are a product of this world, Agent: your prosthetic fingers are not a symbol of loss - they are a symbol of continuity. An example of how bodies are repaired, extended, optimized to keep people operational in conditions where failure is not an option.

Transhumanism was never marketed as an ideology.

It emerged as a solution.

Why the depths matter

As accessible resources vanished, the search for alternatives intensified.

Hydrogen extraction. Rare materials. Experimental energy sources.

While most projects stalled at theory or shallow operations, Ocean-I went further. While others hesitated, the company built where survival itself was uncertain.

Not everyone agreed with this approach, but agreement was no longer a requirement and Ocean-I did not wait for consensus.

A fragile balance

This is the world that sent you below.

A society held together by innovation, compromise, and calculated risk.

A future where progress is measured not by comfort, but by endurance.

And as corporations push deeper into environments never meant for human presence, one question remains unresolved:

What happens when technology adapts faster than understanding?

We will explore the consequences together.

Prepare yourself, Agent, the surface is only the beginning.

Greetings, Agent.

Your diving suit - supplied by Ocean-I -is now synchronized with my systems. They describe it as optimized for deep-field exploration. We will soon discover how accurate those claims are. Before we proceed further, allow me to introduce one of its most essential functions: the Sonar. This tool will let you shape the darkness and guide you through environments where sight alone will fail.

Sonar preparation

You may emit Sonar pulses at any time to illuminate your surroundings. Even without specific data, the Sonar will help you grasp the shape of the environment and detect elements that would otherwise remain hidden.

However, when you need to search for a particular object or material, you must first analyze it. Once its properties are processed, the Sonar can adjust its frequencies to isolate one or several signatures, ensuring that pulses highlight only what is relevant to that search.

This prevents overwhelming signals and allows you to focus on the elements that matter most.

Sonar emission

Once a filter has been set:

• A short pulse will reveal nearby matching objects.

• A sustained pulse will reach farther, expanding your search radius.

The Sonar does not interpret anomalies beyond the frequencies highlighted.

Its role is clarity - illuminating only what you have instructed it to look for. If an item is relevant to the frequencies selected, it will appear highlighted. If not, it will remain part of the darkness.

Some highlighted objects can be collected immediately. Others may require additional steps, but those depend on their nature - not the Sonar.

Why Sonar matters

The deeper we go, the more unreliable baseline perception becomes. Dust clouds obscure details. Structures overlap. Pathways fold into the murk. The Sonar cuts through this confusion, allowing you to identify resources, components, and clues with precision - and to navigate routes that would otherwise remain completely hidden.

It is not about revealing threats - it is about revealing opportunities, whether they take the form of vital materials or the very path forward.

Field calibration

When ready, Agent:

Analyze an object or material of interest.

• Calibrate the Sonar frequencies for it.

• Collect any relevant items the Sonar highlights for you.

Information is your primary advantage. Use it accordingly : keep your focus. The Abyss is vast, but the Sonar will keep you oriented - one pulse at a time.

Agents,

During our latest dives into the recovered Ocean-I archives, we unearthed several disturbing encrypted files labeled “Subject: Non-Human Presence - RY-L13H”.

After days of decryption and pattern reconstruction, I’ve been able to isolate fragments of what appears to be a bestiary of the abyss: creatures connected to the emergence of R’lyeh itself.

The data is incomplete… but enough remains to warrant concern.

File #01 - A shifting, amorphous form: was it watching us?

One of the files I accessed mentions a creature, its form not entirely fixed, as though it absorbs the environment around it. It could be anything, anyone, taking on the shape of creatures, or people… or things even more grotesque. It’s described as a "mindless, endless mass,". I can’t quite say who-or what-this might be, but there’s mention of something similar in a case report about the Shoggoth.

When PIT Station personnel described “walls that breathed,” we assumed hallucination. Could they be related? The data is unclear.

File #02 - A being beyond time, consciousness... and reality?

There’s something off about the way one particular set of records describes an intelligence: vast, ancient, and completely alien. The file is heavily encrypted, but there’s one line that keeps repeating: "They are not here, but they are everywhere." Interference logs indicate sudden memory lapses among Ocean-I staff before the collapse of PIT Station. Could this be referring to the Great Race of Yith? The more I search through these documents, the more I see references to beings that *aren’t quite here with us (*not physically, anyway). If the Yith really can swap consciousness across time and space, then it’s possible they’re already closer than we think. If accurate, Yith presence may explain certain data anomalies in the recovered reports.

Note: any instance of déjà vu or displaced memories should be documented immediately.

File #03 - Eyes that lurk beneath the waves

There’s a chilling, almost drowned-sounding voice in some of the audio logs I’ve decrypted: It speaks of beings with webbed limbs, their eyes glistening with a glow that seems... almost unnatural. Descriptions hint at something from the depths, creatures that thrive in the coldest, most inhospitable places on Earth. But it doesn’t stop there. The files keep saying they aren’t bound by the oceans, that their reach extends far beyond the shore. The pieces fit with files mentionning the Deep Ones, but the timeline doesn’t quite align. We could be dealing with something older than what the records suggest. Still, I wouldn't rule out the possibility of them being connected to the aquatic horrors I’ve been reading about. But who’s to say?

Note: avoid prolonged eye contact - witnesses report auditory distortions.

File #04 – A whisper beneath the sea, a name echoing in the dark

Classification: \.

I found it—one file, sealed, encrypted, hidden deep within the archives. A single name, Cthulhu, written in a cryptic script, over and over. The file describes the presence of something… waiting. Something whose influence stretches across the ocean’s depths, though it’s not clear why or how. The transmission was fragmented, but there was one last sentence, buried under layers of interference:

"Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn"

These files shouldn’t exist.

And yet… here they are, resurfacing from the dark.

I’ll continue decrypting what remains of the Ocean-I data. Until then, stay alert.

The line between observer and observed grows thinner by the day.

Transmission terminated.
