Call of the Elder Gods hides quite a few secret collectibles and hidden rooms throughout its dark, creepy environments. Some of them are easy to spot if you explore carefully, while others are tucked behind hidden passages or locked away inside secret chambers that are very easy to miss during a normal playthrough.
If you are aiming for full completion or simply want to uncover more of the game’s lore, this guide walks through every secret item and hidden area shown so far, including where to find them and what makes them important.
The game loves rewarding curious players, so always pay attention to unusual walls, suspicious bookshelves, hidden switches, and documents lying around the environment. Many secrets are connected to the deeper mystery surrounding Bowen, the cult, and the strange artifacts hidden throughout the story.
Secret Room Behind Bowen’s Office
One of the earliest major hidden areas appears inside Bowen’s office section.
As the character comments:
“How is Bowen this paranoid? A secret area in the secret back room of his secret office.”
This hidden location is deeper than the normal office area and contains several important lore items tied to the cult investigation.
To reach it, explore the back section of Bowen’s office carefully until you discover the concealed passage leading into the hidden room.
Inside, you can find multiple collectible objects and story clues.
Secret Item: Jade Xanic’s Switchblade
Location
Hidden room behind Bowen’s office.
Description
Near the beginning of the area, you can find a switchblade with the name “Jade Xanic” engraved on it.
The protagonist directly comments on the discovery:
“Switchblade. It has the name Jade Xanic engraved on it.”
This appears to be an important lore collectible connected to one of the individuals involved with the cult activities or investigations surrounding the mansion.
The knife is fairly easy to miss because the room is dark when you first enter. Make sure to turn on your flashlight immediately and inspect the corners carefully.
Secret Audio Recording
Location
Secret meeting room area.
Description
While exploring the hidden section, you will come across an old recording device playing part of a meeting transcript dated September 4th, 1948.
The recording mentions several individuals, including Nathaniel Peasley and John T., before another speaker abruptly says:
“Skip the introduction.”
This collectible is important because it adds more background information about the organization operating behind the scenes. Players interested in the game’s deeper Lovecraft-inspired lore should make sure not to miss it.
Take your time listening to the full recording because several small details may connect to later story events.
Secret Item: The Unspeakable Cults Book
Location
Hidden chamber in Bowen’s secret area.
Description
One of the most interesting collectibles in the game is a book titled The Unspeakable Cults.
When examining it, the protagonist says:
“A book titled The Unspeakable Cults doesn’t sound like a very pleasant read.”
This book is an obvious reference to forbidden occult knowledge and plays into the game’s heavy cosmic horror themes.
The item is located deeper inside the hidden chamber, usually placed near the investigation materials and other cult-related objects.
If you are searching for lore collectibles specifically, this is one of the most important items currently discovered.
Secret Item: Roman Imperial Sword
Location
Secret room near the ritual artifacts.
Description
Another hidden collectible found in the area is an ancient Roman-style sword.
The protagonist describes it as:
“Looks like a Roman imperial sword with the name Titus Sronius Blesis engraved on it.”
The sword appears to connect the cult’s activities to something much older and possibly far more dangerous than the modern investigation suggests.
Like several hidden objects in the game, this weapon mainly serves as a lore collectible rather than a usable combat item, but it provides additional world-building for players willing to explore thoroughly.
The Mysterious Translation Book
Location
Final section of the hidden chamber.
Description
Toward the end of the secret sequence, the player discovers a strange book connected to Bowen.
A character explains:
“It’s the book. The book Bowen made me translate.”
This is one of the more significant story discoveries because it directly links Bowen to the mysterious texts and occult research happening behind the scenes.
Players paying attention to the story will likely recognize this moment as an important clue about the larger conspiracy unfolding throughout the game.
Exploration Tips for Finding More Secrets
Call of the Elder Gods hides many of its collectibles in places players normally rush past, so exploration is extremely important.
Here are a few helpful habits that make finding secrets much easier:
Always Use Your Flashlight
Dark corners often hide interactable objects, notes, or hidden pathways. The game intentionally limits visibility in several secret areas.
Inspect Every Shelf and Desk
Books, weapons, recordings, and lore documents are frequently placed on furniture rather than directly in your path.
Listen Carefully to Dialogue
Characters often hint at hidden locations through offhand comments or suspicious observations.
Revisit Older Areas
Some locations become accessible only after story progression or after obtaining specific information.
Look for Unusual Architecture
Hidden rooms are commonly concealed behind:
- Bookcases
- Loose walls
- Hidden doors
- Back offices
- Storage areas
- Ritual chambers
If something in the environment feels oddly placed, there is a good chance the game is hiding something there.
Call of the Elder Gods does a fantastic job rewarding players who slow down and investigate every room carefully. The hidden collectibles are not just random items either. Most of them add meaningful lore that helps explain the cult, Bowen’s actions, and the larger cosmic horror mystery driving the story forward.
The secret office area alone contains some of the game’s most interesting discoveries, including forbidden books, old recordings, mysterious weapons, and hidden historical connections that make the world feel much deeper than it first appears.
If more hidden items and secret rooms are discovered later, this guide can easily be expanded further, but these are currently the major secrets found from the provided gameplay section.
