When Big Bad Wolf Studio unleashed Cthulhu: The Cosmic Abyss in April 2026, it promised something more than your typical horror game. Blending cosmic dread with elaborate puzzles, it aims to immerse players in a mysterious world where every item and clue might unlock secrets about the universe or drive you deeper into madness. But the stakes are high — how effectively does this game balance exploration, puzzle-solving, and atmosphere to hold your attention?
At the core of Cthulhu: The Cosmic Abyss is the intricate system for discovering and interacting with items. Puzzle-solving here isn't about simple riddles; each challenge often spans entire buildings with multiple interconnected rooms. You'll be running between areas, piecing together clues and gathering objects to make sense of the unfolding mystery.
Your primary tool to navigate these labyrinthine puzzles is a sonar device designed to detect specific materials hiding in the environment. Unlike generic highlight mechanics that overwhelm you with endless hints, this sonar focuses solely on materials you select, offering an intelligent way to zero in on only the items relevant to your current objectives.
For instance, in Chapter 2, you encounter a crown composed of Ancient Blood and Orichalcum. Knowing this, you can configure your sonar to search specifically for these substances, which guides you directly toward matching crowns you need to collect. This mechanic adds a refreshing layer of strategy, encouraging you to carefully analyze documents and clues instead of relying on passive hand-holding.
This targeted sonar approach cleverly avoids information overload. With hundreds of examine-worthy objects scattered about, indiscriminately highlighting everything would dilute the tension and trivialize the brain-teasing puzzles. Instead, you’re constantly prompted to think critically about what materials are important and why, reinforcing the investigative mood of the game.
It’s often said that subtlety can be a game’s best friend, and here it shines through. The design challenges you to pay attention to details — some items won’t even reveal their composition outright, requiring you to piece together evidence from various notes and documents. This mechanic highlights Big Bad Wolf's knack for environmental storytelling and puzzle design, rewarding players willing to invest the mental effort.
The game is filled with moments like these, with some items not even telling you what they’re made of, as the game instead trusts you to read documents to find the type of materials you need to search for on your own.
If the game simply highlighted every object the player could examine with a single click of their sonar, it would result in information overload due to the number of objects in the world and would invalidate most of the game’s puzzles.
The brilliance of the sonar is how much it encourages the player to think through what they’re examining instead of just letting them turn their brain off like similar mechanics in other games. I find this mechanic to be the best showing of Big Bad Wolf Studio’s strength as game designers, and I hope that others agree with me on this.
The puzzles themselves are a divisive feature. They aren’t your quick or obvious brainteasers; instead, they demand patience and persistence. Players may find themselves wandering back and forth, testing different combinations and revisiting clues repeatedly. This method can grind patience gears, but it rarely cheats you with unclear or unfair challenges.
Even when stuck for hours, it feels like you’re missing just one vital insight rather than being blocked by poor design. Every breakthrough comes from spotting a previously overlooked hint tucked away in journals or requiring an unorthodox association. This kind of puzzle evokes genuine 'ah-ha' moments, making the payoff deeply satisfying if you’re up for the challenge.
Chapter 5 stands out as particularly tricky, thanks to unique gimmicks that test your ability to think laterally. While some may find these hurdles frustrating, the overall puzzle flow avoids falling into random trial-and-error territory. The game respects your intelligence and rewards your perseverance, though it certainly won’t hold your hand.
Even when some of them took me literal hours to complete, it always felt like I was the one missing something and not that the game was withholding information. Every time I found the true solution to a puzzle, it felt like I had just noticed a vital clue I had overlooked, and not like I was throwing everything at the wall until it worked.
The clues do exist, they might be tucked away in a note you found or require a bit of thinking outside the box to truly understand, but they exist. I would be lying if I said that there weren’t several annoying puzzles in this game, with chapter 5 being a stand-out example due to that chapter’s particular gimmick, but nothing felt like it was badly designed.
This is a type of puzzle design I can enjoy, as the moment the player goes “Ah-ha!” and finally progresses is invigorating, but it can easily turn many off the game due to the hands-off nature of the game, even when you enable tips. The best advice I can give is that if you are the type of person who can tolerate spending hours on a single puzzle, then Cthulhu: The Cosmic Abyss will scratch that itch for you.
Among its standout mechanics is the Corruption System . As you navigate each chapter, your choices influence the degree of mental corruption you incur from the Deep Ones. Many puzzles can be solved in two distinct ways—either embracing corruption or resisting it. The amount of corruption you accumulate steers you toward one of six vastly different endings.
One catch is that avoiding corruption is significantly harder than succumbing to it. The clues players find often reflect the fate of his fallen predecessors, pointing toward the corrupted solution. This design encourages an initial playthrough where mental decay feels almost inevitable—a fitting nod to Lovecraftian fatalism.
This approach feels deliberate; most will likely experience a predominantly corrupted path on their first run. The alternative, less maddening endings become a conquest for dedicated players who want to unveil every secret and steer clear of the creeping insanity. It adds replay value and a greater narrative depth.
However, this system isn’t without flaws. Some segments seem to force corruption unfairly, sometimes as a result of a single misstep or an unavoidable interaction. The game generally treats corruption as a negative status in the UI, so feeling punished in these moments undermines immersion and can be frustrating.
A first playthrough of Cthulhu: The Cosmic Abyss is almost guaranteed to end with the player being mostly corrupted, as the less madness-inducing methods of progressing are significantly harder to figure out.
I believe this was an intentional design decision, as being sucked into a madness beyond their comprehension is what most would want from a single playthrough of a Cthulhu game, with the extra endings where the player can avoid this Corruption being more of a bonus for those dedicated enough to find them.
However, even though I greatly enjoyed the concept of the Corruption mechanic and overall liked its implementation into the game, I do have some problems with it. Several parts of the game seem to force Corruption on the player for either no reason or because they made one wrong step, and because Corruption is generally treated as a negative status by the UI, it feels like I’m being punished for no reason a lot of the time.
An Ocean of Technical Issues
Despite these intriguing systems, Cthulhu: The Cosmic Abyss suffers from technical shortcomings that hamper the experience. Frame rates fluctuate noticeably and often drop during the most tense cutscenes, breaking the mood and making the game feel less polished.
Loading sequences add to the woes. The UI frequently appears long before the environment, sometimes lagging by over 40 seconds, leaving players stranded in darkness. This creates an uneasy uncertainty about whether the game has crashed or is simply taking its time.
The fears are justified, as frequent crashes occurred on PlayStation 5 during extended play sessions. Autosave intervals are too sparse, forcing players to repeat sizable chunks of investigation after a crash. This makes the setbacks feel especially punishing and disrupts the carefully crafted pacing.
Audio glitches add to the frustration, particularly in watery areas. Over time, static noise will replace normal sound effects whenever actions are performed, requiring a full restart to resolve. This bug further detracts from the game’s atmosphere and immersion.
The only way to fix these audio issues was to restart the game, which (again due to the infrequent autosaves) tended to be just as painful as listening to the static play in my ears.
All Too Compressible Horrors
As a Lovecraftian horror game, Cthulhu: The Cosmic Abyss struggles to capture the essence beyond its mechanics. Lovecraft’s cosmic dread is rooted in the unfathomable and the unknowable, yet this game’s horrors often feel too tangible and comprehensible.
True cosmic horror thrives on paranoia and an ever-present tension that pays off in subtle ways. When the terrors become too easily understood, the sense of existential fear is lost. Unfortunately, this dampens what could have been a more resonant experience in a genre defined by its unsettling ambiguity.
