Always open Norah's journal immediately after interacting with a new document or mural. If the sketch doesn't appear, you may need to rotate the object or view it from a different angle to trigger the clue registration.
Prologue and Chapter 1: The Investigation Begins
The story starts in a familiar domestic setting that quickly spirals into the occult. In the Prologue, your primary goal is to unlock the journal and solve the Christmas safe puzzle. This establishes the game's core loop: find symbols in the environment, match them to numbers or patterns, and apply them to a lock.
The Christmas Safe
Match the non-working piano keys (spiral, star, triangle) to the numbered baubles on the tree. The resulting code is 146.
The Everhart Vases
In the garden, rotate each vase to face its corresponding landmark: the moon gate, the well, the greenhouse, the firepit, and the tree stump.
In Chapter 1, you must infiltrate the Everhart Manor. The centerpiece of this chapter is the library's secret route. After retrieving the missing book from the greenhouse, you must arrange the shelf in a specific linguistic order derived from the portrait ages found throughout the house.
| Book Title | Position | Clue Source |
|---|---|---|
| PRAETERITA | 1st | Youngest Portrait |
| MUTARE | 2nd | Chronological Order |
| NON POSSUMUS | 3rd & 4th | Chronological Order |
| SED FUTURA | 5th & 6th | Chronological Order |
| PROVIDERE DEBEMUS | 7th & 8th | Oldest Portrait |
In Chapter 1, don't forget the Bouquet trophy. Take the white flowers from the greenhouse and place them on the lady statue's bench in the garden before entering the secret fireplace passage.
Chapter 2 & 3: Deep Sea and Secret Societies
Chapter 2 takes you underground, where you must manage power systems and chemical separation. The black ooze machine is a common sticking point for many players. You must manipulate the tanks until exactly four units of black ooze occupy the second tank.
Power the Gear
Locate the green power box and flip switches 2, 3, and 5 to stabilize the gauge for the oxygen cylinder machine.
Separate the Ooze
Use the valves to drain water into the small tank while keeping the black ooze in the main chamber. Repeat until the 4-unit threshold is met.
Tower Sequence
Use Harry's piano-panel to raise the towers. The standard sequence is 1-2-4-5 + C. For the secret "Best Served Cold" trophy, use 3-5-2-4.
Chapter 3 shifts focus to the Miskatonic University and the Starry Wisdom Society. This chapter is heavy on logic and identity puzzles. You must develop a cult photo and use it to identify five key members of the society to unlock the central elevator.
| Position | Member | Role | Symbol | Mask |
|---|---|---|---|---|
| I | Howard | Dilettante | Crocodile | Crocodile |
| II | Patricia | Biologist | Pot/Semicircles | Cat |
| III | Felix | Archaeologist | Snake | Long-beak |
| IIII | Eugene | Psychiatrist | Little Bird | Dog |
| IIIII | Larry | Astronomer | Eagle | Eagle |
Once the table is filled correctly, the center button will glow blue. Pressing it calls the elevator, allowing you to bypass the Inner Sanctum.
Chapter 4 & 5: Decryption and Alien Technology
As you move into the latter call of the elder gods chapters, the puzzles become increasingly mechanical. Chapter 4 introduces the Enigma machine, requiring you to switch between Harry and Evangeline to route power and decrypt radio messages.
| Message ID | Reels | Dials | Plugs |
|---|---|---|---|
| GMR (Flashback) | III - I - II | 15 - 26 - 01 | UA / WF |
| UZW (Radio) | II - III - I | 23 - 13 - 02 | GE / FM |
| BDA (Radio) | III - II - I | 19 - 25 - 06 | PW / CR |
| SSW (Radio) | I - III - II | 15 - 25 - 25 | ZI / HP |
Chapter 5, "Prisoners of Ice," features the most alien environments in the game. You must communicate with a captive creature using a brainwave machine. The correct dial settings are A3, B1, C4, and D3. Following this, you will navigate to an ancient observatory to calculate coordinates for a spaceship.
Chapter 5 Critical Steps:
- Set brainwave dials to A3, B1, C4, D3
- Identify Earth and Era 2 in the Observatory
- Input the constellation symbol at the Central Map
- Translate 89345 into alien numerals for the spaceship
- Use the mind-swapping chair to return to your body
During the Chapter 4 power routing, remember that Harry controls the main consoles while Evangeline handles the physical fuse boxes. If you can't progress, try switching characters to see if a new interaction has opened up in the alternate location.
Chapter 6 and Final Endings
The final chapter, Pna-ko-tus, brings all mechanics together. You will solve a massive ball-machine puzzle that requires precise timing. The goal is to recreate specific symbols shown on the ruins' walls by launching balls into a rotating mechanism.
Final Puzzle Logic:
- Pattern 1: Start the 2nd ball; start the 1st ball when the 2nd reaches the first quarter.
- Pattern 2: Launch the 3rd and 4th balls simultaneously to align the final stone door mechanism.
The game concludes with a narrative-defining choice. Unlike many modern games, the ending is a binary branch based on your final interaction with Evangeline.
The Harry Ending
Choose to stop Evangeline and take her place. This resolves the story through the Professor's perspective and unlocks the "Hard-Headed" trophy.
The Evangeline Ending
Choose to let Evangeline sacrifice herself. This follows her character arc to its completion and unlocks the "Always Trust the Doctor" trophy.
Reaching either ending will roll the credits. To see the other outcome, simply select "Continue" from the main menu; the game will place you right before the final decision.
