Layers of Fear

A cumulative timer - look directly at any painting(s) for a total of 60 minutes. It accrues over a thorough playthrough and all your extra ending runs, or you can just stand and stare at a painting (AFK) to farm it.

Let a ghost or hazard catch and kill you once - walk into the wife-ghost or a lethal encounter. There's no permadeath, you just respawn. Easiest at the first ghost chase.

Finish the story and reach any of the three endings - unlocks automatically on completion, whichever ending you get.

Reach one of the two conclusive endings (self-portrait or wife-and-child) rather than the default loop. The self-portrait ("selfish") ending is easiest - focus on your art, ignore the wife-and-child memories, and don't get caught.

Collect all 16 family mementos (photos and notes) across Chapters 1-6. Use a locations guide; the progress carries across the multiple runs you'll be doing anyway.

Open 100 drawers and cabinets, cumulatively. Comes naturally if you search thoroughly; otherwise just open drawers repeatedly in any room.

In the sequence where you hear a crying woman behind you and a sign warns you not to look back, keep walking forward through the door without turning around.

(Inheritance) Trigger every childhood-memory flashback by visiting the relevant rooms (kitchen, basement, mother's bedroom, daughter's room...). The screen blurs and you shrink to child height during them; hard to miss on a thorough run.

Pick up your first Whispered Word collectible - unlocks automatically the first time you grab one, early on. The first-collectible counterpart to Whispers long forgotten.

Near the start, pull the sheet off the covered unfinished painting (your Magnum Opus) in the studio. Story-required, unlocks in Chapter 1.

Find a telephone in the house (in the Chapter 5 study area) and dial 9-1-1 on it.

(Inheritance forgive ending) Take the father's side throughout: play the crayon piano tune, pick up the toy train and all the birthday cakes, tap the dog off the sofa, lock the utility closet, keep looking at him during his story, paint the canvas with paint, and let the dog out of the kitchen. Mutually exclusive with Too Little, Too Late.

See all three base-game endings (loop, self-portrait and wife-and-child) on the same save slot. Steer to a different ending each run - and because the hidden ending-score is set well before the final chapter, the reliable method is a fresh New Game per ending rather than reloading the last chapter.

(Inheritance) During the quarrel/argument vision, make consistent choices favouring the same parent (all mother-side or all father-side) throughout, without switching sides.

Pick up your first family memento - unlocks automatically with the first of the 16, early on.

On the loop/wife-portrait ending, after the ending cutscene (before you return to the workshop) go to the room with the broken couch and white table and open the book on the floor in front of the couch - it shows a sketch of the Bloober Team developers' faces.

(Inheritance) On the second trip into the fables (use the crayon on the canvas), pull the sword from the stone behind the canvas, then find the serpent and walk into it to slay it. You'll need the paint colours (red, black, yellow, green) to get there.

Pick up your first rat/rodent drawing - unlocks automatically with the first of the 16 rat sketches.

(Inheritance) Collect all 9 memory/puzzle drawings around the house (mousetrap closet, kitchen pantry, basement piano, the painting puzzle, mother's-room closet, office, child's room, the discarded-paintings room, and the side table before the locked door) and assemble them. Also gates the true ending, The Tree and the Apple.

(Inheritance true/secret ending) On the father's path, assemble all 9 puzzle drawings (The Big Picture), shine your flashlight on the completed puzzle for about 30 seconds then switch it off to reveal a glow-in-the-dark blue-paint map, and open the hidden cupboard behind you. A distinct run from the other two DLC endings.

(Inheritance DLC) Read/collect all 24 collectibles (notes and drawings) in a single continuous run of the DLC - they don't carry across runs, so grab everything with a locations guide before you finish.

Find the "Furboy" portrait and stare at it for a cumulative five minutes (you can stand still and let the timer run).

(Inheritance refuse ending) Take the mother's side throughout: play the gramophone, collect the birthday cakes, look away from the father during his story, and paint the canvas with crayon rather than paint. Mutually exclusive with Let Bygones Be Bygones.

Walk 1,000 steps, cumulatively - unlocks naturally through normal exploration early on.

Collect all the Whispered Word items - the in-game tracker counts 22 and it pops at 22/22. Use a locations guide, but ignore ones that list 26-28 (they over-count).

Collect all 16 rat/rodent drawings across the six chapters (Ch1: 3, Ch2: 1, Ch3: 6, Ch4: 2, Ch5: 3, Ch6: 1). Use a locations guide.
