Chapter 3: The Starry Wisdom Secret Room
The most significant of the call of the elder gods secret room locations is found in Chapter 3: "A Guide to the Members of the Starry Wisdom Society." This room is not just a collectible spot; it is a fully realized hidden area that reveals the "man behind the curtain" of the cult's operations.
To access this area, you must reach the final stages of the chapter after solving the Egyptian statue table and calling the elevator.
Reach the Upper Office
After completing the statue logic puzzle and taking the lift up, you will arrive at an office area just before the final narrative room of the chapter.
Locate the Entrance Columns
Look at the large double doors leading to the final chamber. Flanking these doors are two ornate stone columns.
Activate the Hidden Buttons
Walk to the side of the left column to find a small, recessed button. Press it. Repeat this for the right column. You will hear a mechanical click.
Enter the Secret Room
A section of the wall near the bookshelf will slide open, revealing the secret room and unlocking the "Pay No Attention to the Man Behind the Curtain!" achievement.
Ensure you activate these buttons before interacting with the final story object in the next room. Once the ending cutscene for Chapter 3 triggers, you cannot return to this office without restarting the chapter.
Secret Object Locations by Chapter
Aside from the main secret room, players must find specific "Secret Objects" to earn individual chapter trophies. These are often small figurines or occult items that represent Lovecraftian lore.
| Chapter | Achievement Name | Exact Location Description |
|---|---|---|
| Chapter 1 | The Terrible Old Man | 1. Dark-room bench upstairs / 2. Balcony behind the chair / 3. Garden exit sacks |
| Chapter 2 | Peaslee's Parliament | Follow the left wall to the water, then walk the narrow land strip to the end |
| Chapter 4 | Unspeakable Cults | Enter the damaged building on the left; check under the first bed on the right |
| Chapter 5 | The Roman Quaestor | In the tall-hallway building, enter the left room before the beam; use the far-right ramp |
| Chapter 6 | It Belongs in a Museum! | After the large-door puzzle, go down the ramp and check behind the first pillar on the left |
When searching for secret objects, look for "out of place" geometry. The developers often place these items at the end of paths that seem to lead to dead ends or "out of bounds" areas.
The Chapter 6 Hidden Cube and Meta-Secrets
One of the most elusive call of the elder gods secret room locations isn't a room at all, but a hidden geometric anomaly in the final ruins of Pna-ko-tus. This secret is a nod to the developer's previous titles and requires a specific interaction sequence.
How to Find the Hidden Cube:
- Solve the main Chapter 6 ball-machine and light-beam puzzle.
- Pass through the opened Great Door, but do not go down the main slope.
- Turn left and find a narrow gap in the rock wall.
- Locate the floating cube in the hidden alcove.
- Interact with the cube sides in order: 0 diamonds, 1 diamond, 2 diamonds, and so on.
Completing this sequence unlocks the "Wrong Game... or Maybe Not" trophy. Additionally, players should keep an eye out for the "Meta-Reference" key in Chapter 3. After the interrogation sequence, look for a blue floating key near a garage in the dreamscape—this is a direct reference to Out of the Blue Games.
Finding the hidden cube is often the last step for many players. Once the interaction sequence is complete, the trophy should pop immediately.
Journal Completion and Clue Locations
Your search for call of the elder gods secret room locations is often tied to completing Norah's journal. Many clues are located within or near these secret areas. To earn the "...For the Sake of Clarity" achievement, you must collect all 113 clues.
| Chapter | Clue Count | Key Investigation Areas |
|---|---|---|
| Prologue | 11 Clues | Piano keys, Christmas tree ornaments, safe documents |
| Chapter 1 | 18 Clues | Library portraits, garden vases, greenhouse books |
| Chapter 3 | 27 Clues | Cult member offices, developed photos, statue hieroglyphs |
| Chapter 5 | 29 Clues | Brainwave machine patterns, Observatory murals, spaceship console |
| Chapter 6 | 7 Clues | Waterfall signs, final door mechanisms, tent documents |
If you are missing a single clue, check the "Brainwave Machine" in Chapter 5. You must open the journal after every successful combination (A3, B1, etc.) to ensure the wave pattern is recorded as a unique clue.
Frequently Asked Questions
Q: Are there any missable secret room locations in Call of the Elder Gods?
Technically, no. While you can progress past a secret room in a single playthrough, the game features a Chapter Select menu that allows you to jump back to any specific chapter to collect missing items or enter secret rooms without losing your overall progress.
Q: What do I get for finding all the secret objects?
Each chapter has a specific achievement tied to its secret objects (e.g., 'The Terrible Old Man' for Chapter 1). Finding all of them is a requirement for the 100% completion achievement 'The Call of the Elder Gods'.
Q: How do I trigger the secret room in Chapter 3 if the buttons aren't working?
The buttons on the columns only become active after you have successfully identified all cult members at the Egyptian statue table and called the elevator. If they aren't interactable, ensure you have finished the logic puzzle first.
Q: Is there a secret ending associated with the secret rooms?
No. The secret rooms provide additional lore and achievements, but the ending of the game is determined solely by the final choice you make in Chapter 6 regarding Evangeline's sacrifice.
The journey through Call of the Elder Gods is as much about observation as it is about logic. If you find yourself stuck, always return to the journal. The answers—and the paths to the game's deepest secrets—are often hidden in plain sight within Norah's sketches.
