Cthulhu: A Guide to Chapter 1 of the Cosmic Abyss

Cthulhu: The Cosmic Abyss marks the latest addition to the Lovecraftian horror genre, yet it is essential to note that its core is rooted in puzzle-solving mechanics. While the game undoubtedly delves into horrors beyond comprehension, it challenges players primarily through intricate puzzles designed by its developers.

The thrill of any puzzle game lies in unraveling the challenges set before you. However, it’s natural to seek assistance when stuck. This comprehensive guide, alongside six more that are forthcoming, will navigate you through each chapter of Cthulhu: The Cosmic Abyss.

Chapter 1: Overview and Guidance for Cthulhu: The Cosmic Abyss

A character stands in front of closed double doors with a message indicating tutorial movement unlocked. — Welcome to Mei’s residence.

The opening chapter serves as an introduction to the game’s mechanics, laying the groundwork for the subsequent six chapters. Players will explore how to interact with their surroundings, uncover hidden clues, and utilize the environment to engage with the arcane aspects of R’lyeh.

Upon reaching Mei’s residence, initiate your journey by veering left at the entrance. Here, you’ll locate a method to gain entry — assisting Elsa in unlocking the front door. Move a potted plant, allowing you to crouch beneath debris, which will lead you upstairs.

Once you’ve entered the home, head to the right into the first room before descending the stairs to locate Mei’s phone. Familiarizing yourself with the various objects in this area will enhance your understanding of the game’s mechanics, as examining them is part of the introductory tutorials.

After allowing Elsa to enter, your next objective is to gather further information about Mei. Pay attention to the room where Elsa investigates Mei’s research tablet; a stone nearby can be collected and analyzed. This exercise introduces the player to the clue-analysis mechanic, crucial for revealing Sonar frequencies and unearthing additional hints.

In the next room, players will encounter a fragmented image composed of multiple pages affixed to a wall. The remaining pieces necessary to complete this image are scattered on the floor and a nearby desk. For reference, the completed image is featured as the third visual in the gallery below.

Completing the assembly of the image and conversing with Elsa transitions you into the next segment of the chapter. Head downstairs toward the kitchen, take a left, and follow the long black cord leading to the basement door. Approaching this door triggers an animated sequence.

Throughout your exploration, multiple interactive items provide opportunities for dialogue among Noah, Elsa, and Key. Be attentive to voice recordings from Mei and various notes scattered about; engaging with these elements enriches your understanding of the narrative. However, keep in mind that it’s not necessary to uncover every mystery within Cthulhu: The Cosmic Abyss. Assess which clues are essential for progression and which simply serve to deepen world-building.

After investigating the basement and encountering the enigmatic organic matter, Elsa and Noah will hypothesize that it resembles a portal. Your next challenge involves discovering how to activate it, recognizing its connection to the image you’ve reconstructed. Position the correct stones in their respective slots on either side of the portal — refer to the second and third images in the gallery below for guidance.

Upon successfully opening the portal, a cinematic moment ensues, leading you into the mysterious realm of R’lyeh. As you step to the left, watch for another cutscene that culminates the chapter.

In this chapter, there are no collectibles or upgrades to search for, granting you the freedom to explore at your own pace and absorb the investigation mechanics. The game effectively introduces a wealth of information at the start, making it critical to familiarize yourself with each new gameplay element as it appears.
