PC Critic Reviews

A wonderfully deep (ha!) puzzle detective game, Cthulhu: The Cosmic Abyss treads a fantastic line of respecting the source material, updating it in a fresh way, and delivering some deliciously restrained horror.

Despite a minor hiccup with a save issue, the overall polish and responsiveness from the developers leave a strong impression. For players who enjoy narrative- driven investigations with psychological depth, this is a journey well worth taking.

Cthulhu: The Cosmic Abyss is, crashes and caveats aside, an excellent game. Key is a triumph, the puzzles are imaginative, and the final chapter earns everything it demands of you. I’ve spent about 12 hours with it and I find myself wanting to talk about it with everyone who has ever shared even a flicker of an interest in Lovecraft with me. It’s a cosmic horror that brings classic tropes into futuristic dressing and manages to do that well. What’s not to like?

Cthulhu: The Cosmic Abyss is a first-person 3D investigative horror adventure strongly focused on exploration. Gameplay revolves around collecting clues, reading documents, and solving environmental puzzles, with the combination of scanner and sonar helping to mitigate classic pixel hunting. The absence of fast-paced combat is offset by a strong atmosphere. The integration between classic H. P. Lovecraft elements and modern technology, such as the AI assistant Key, works very well. The need to read notes and logs to progress may not appeal to action-oriented players, but this approach feels like a natural evolution of the adventure genre. And it works.

Big Bad Wolf's Lovecraftian investigation horror experience pulls out all the stops to corrupt the brains of many a Cthulhu fan. From dazzling locations full of references to volumes of H.P. Lovecraft lore, Cthulhu: The Cosmic Abyss spares no detail. The fact that you have to scan every square centimeter until you lose your mind, and still run the risk of missing vital information, might well be a low point for some. With a bit of bad luck, it drives you to mental corruption, but it is a sacrifice that an audience with The Great Old One requires.

Cthulhu: The Cosmic Abyss has a lot to offer for those looking for an immersive, narrative-driven horror thriller. Its gameplay doesn’t demand quick reflexes or wanton destruction, but rather deduction skills and attention to detail. I don’t see everyone being a fan of this title, but for those who are really big into Lovecraft, this is probably exactly what you would want from a game tackling the mythos, one that is all about questions and the unfortunate answers that go with them.

Its puzzles may leave something to be desired, but Cthulhu: The Cosmic Abyss legitimately feels like one of Lovecraft’s dark stories experienced first-hand.

Big Bad Wolf's latest is a visually arresting Lovecraftian deep-dive that prioritizes "big brains" over big guns, but its overly safe structure prevents it from reaching true horror greatness. While the 2053 tech-noir setting is a brilliant spin on the mythos, the thalassophobia here is mostly "vibes" and very little bite. The investigative loop is genuinely high-brow, featuring a complex sonar-based system that rewards meticulous detail-hunting. However, the total absence of combat or persistent physical threats makes the 11-hour journey feel like a guided tour of an underwater museum rather than a desperate struggle for survival. Branching paths and multiple endings provide some much-needed narrative stakes, yet the AI companion, Key, feels like a hollow shell of what a modern interactive partner should be. It’s an essential pick for lore-hungry detectives and tech enthusiasts wanting to push Path-Tracing to its limits, but hardcore horror fans will likely find the lack of "Game Over" consequences a bit underwhelming. A sophisticated investigative gem that desperately needs more teeth.

Cthulhu: The Cosmic Abyss is a must-play game, especially for fans of H.P. Lovecraft’s works. Even though you don’t face a direct threat as a player, the story gradually draws you into this chaos, enriching the gameplay with systems like mind maps, deductions, and corruption to help you reach the end of this fictional world. In short, it’s a valuable title for fans of the genre and players who can muster a bit of patience. Still, it’s a shame it couldn’t have launched without needing the major patch that’s been announced for the future.

Cthulhu: The Cosmic Abyss certainly nails its Lovecraftian atmosphere, especially in some truly daunting set pieces. Its environmental puzzles are also well implemented, offering a high level of challenge that fans of the genre will appreciate. If only the story lived up to the same standard.
