Editor's Note

If you miss a specific action, don't worry about starting a new save. The Chapter Select menu allows you to jump directly to any unlocked chapter to clean up missing journal entries or secrets.

Prologue and Chapter 1: Early Missables

The journey begins in the Everhart Manor. Many players rush through the prologue, missing the chance to interact with the piano or the Christmas tree fully. In Chapter 1, the focus shifts to the garden and the greenhouse, where a specific floral tribute is required for a silver trophy.

1

The Familiar Song

During the Prologue, approach the piano in the Christmas room. Press the keys in this specific order: 6-1-9-11-8 (or follow the symbols: Pentagon, Square, 4th Black Key, 5th Black Key, Star). This unlocks You Looked That Up in a Guide... Again!

2

The Terrible Old Man

In Chapter 1, you must find three specific items. The most missable is the knife found on sandbags to the right of the greenhouse area. You must also pick up the paper on the library mezzanine floor to trigger this trophy properly.

3

The Bouquet Tribute

Inside the Chapter 1 greenhouse, look at the lower shelves on the right for a bouquet of white hydrangeas. Take these to the stone bench in front of Norah’s memorial (near the bridge) and place them there for the Bouquet trophy.

Chapter 1 Secret ObjectsSpecific Location
Object 1On the bench in the dark upstairs room
Object 2Behind the chair on the library balcony
Object 3On the sandbags outside the house
Journal Warning

In Chapter 1, ensure you interact with the gate symbols before unlocking the gate. Once the gate is open, Norah will not record the symbols in her journal, potentially voiding the 100% journal trophy for that run.

Chapter 2 and 3: Logic and Interrogation

Chapter 2 introduces the "Music of the Spheres" puzzle, which holds a clever reverse-logic trophy. Chapter 3 is heavily dialogue-driven, requiring you to embrace your inner brat to secure a specific missable achievement.

Action-Specific Trophies in Chapter 2 & 3:

  • Best Served Cold (Ch 2): After placing the statuette in the tower, do not use the fire sequence. Instead, input the reverse sequence: 3-5-2-4. This freezes the statue and unlocks the trophy.
  • You Damn Brat! (Ch 3): During the interrogation with Caleb Bowen, consistently select the Sarcastic dialogue options. Even when a response isn't explicitly marked sarcastic, choose the most insulting one (e.g., the medical condition comment).
  • Meta-Reference (Ch 3): In the dream sequence after the interrogation, look for a floating blue key behind you once you pass through the garage area.
Chapter 2 & 3 SecretsHow to Find
Peaslee's ParliamentFollow the left wall in the Ch 2 main area to a dark strip of land
Secret RoomHit two buttons on the door frame in Caleb's Ch 3 office
Out of the Blue KeyFloating in the Ch 3 dream world (turn around near the garage)
Puzzle Strategy

In Chapter 2, the "DJ Booth" puzzle requires elevating and rotating buildings. To get all journal entries, enter both the left and right rooms and interact with the murals inside before proceeding to the oil/fire climax.

Chapter 4 and 5: Survival and Subterfuge

Chapter 4 features a snowy landscape and an underwater sequence that references classic adventure tropes. Chapter 5 takes place in a futuristic 2006 setting where technology holds the key to the final clues.

1

The Drowning Trophy

In Chapter 4, during the underwater section, Harry will mention having 10 minutes of air. Simply stand still and do nothing. After a few minutes of dialogue, Harry will drown, unlocking I can hold my breath for ten minutes!

2

Comic Book Collector

During the Chapter 4 flashback (the 1930s office), check the trash bin behind the desk on the left side. Picking up the superhero comic book unlocks This City is Afraid of Me.

3

Office Goof-Off

In Chapter 5, after waking up in the lab, enter the office on the right. Turn on the computer monitor on the far right desk to unlock Leave Him the F*ck Alone!, a nod to the developers' other game, American Arcadia.

Chapter 5 Key ItemsLocation
Mini SwordOn the floor in the Pnakotus library (near the ramp)
Dinosaur MuralsAt the top of the lift in the library area
Celestial PuzzleInteract with the 3:00 dial and spin the dial once
Journal Tip

Chapter 5 has numerous murals. Ensure you interact with the Mammoth, the T-Rex, and the Homo Sapien murals to fill out the "History of Life" pages in the journal.

Chapter 6 and The Final Choice

The final chapter brings you to the heart of Pnakotus. This is your last chance to find the final secret object and complete Norah's journal before the game's emotional conclusion.

The Pnakotic Cube (Wrong Game... or Maybe Not): After opening the massive stone door, do not go down the ramp. Look for a small gap in the rocks to the left. Squeeze through to find a mysterious cube. To unlock the trophy, interact with the sides in order based on the number of diamonds:

  1. Side with 0 diamonds.
  2. Side with 1 diamond.
  3. Continue through to 5 diamonds.

Final Completion Checklist:

  • Find the Translation Book behind the pillar in the first Ch 6 room
  • Interact with all black ooze symbols to open the Pnakotus gate
  • Verify Norah's journal is 100% full (Trophy should pop here)
  • Backup your save or prepare to use 'Continue' for the second ending
  • Complete the game once by sacrificing Harry
  • Reload and complete the game by letting Evangeline sacrifice herself
Ending TrophiesRequired Choice
Hard-Headed to the EndChoose 'Stop Evangeline and take her place'
Always Trust the DoctorChoose 'Let Evangeline sacrifice herself'
Final Warning

The 100% journal trophy ...For the Sake of Clarity usually triggers in Chapter 6 after interacting with the final mural inside the waterfall cave. If it doesn't pop, check your previous chapters for unread letters or unviewed murals.

Frequently Asked Questions

Q: Are there any call of the elder gods missable achievements that require a new game?

No. Every trophy can be obtained via Chapter Select. However, some journal entries require you to restart a chapter if you solved a puzzle too quickly without looking at all the clues.

Q: How do I know if I missed a secret object?

The game features one secret object per chapter. If you finish a chapter and the corresponding secret object trophy (like 'The Roman Quaestor' for Ch 5) hasn't popped, you missed it.

Q: Does the hint system disable achievements?

No. You can use the in-game hint sheets as much as you like without affecting your ability to earn the Platinum trophy.

Q: What is the hardest trophy in the game?

The 100% journal trophy is typically the most difficult because it requires interacting with every single note and mural. Missing even one small scrap of paper will prevent the trophy from unlocking.
