Momento: The Ultimate Guide to All 24 Achievements

This ultimate guide to all 24 achievements in Momento provides a complete, spoiler-managed walkthrough for unlocking every trophy and reaching 100% completion. We've organized all achievements by type—from unmissable story beats to the game's most obscure secrets and multiple endings. Whether you're stuck on a specific puzzle or planning a completionist run, this is the only resource you'll need.

Achievements are grouped into categories: unmissable story progression, collectible-based challenges, puzzle solutions, miscellaneous hidden tasks, and the game's multiple endings. We recommend completing the game once on your own before using this guide for a second, targeted playthrough to mop up the rest.

01

Unmissable Story Achievementstag

These nine achievements are unlocked automatically as you progress through the main narrative of Momento. You cannot miss them. They serve as chapter markers for your journey through the house and its history.

02

Collectible-Based Achievementstag

These achievements require you to find all items in a specific category scattered throughout the game world. They are the most commonly missed trophies on a first playthrough.

Where to Find All 6 Torn Diary Pagestag

Unlocking the Chronicler achievement requires finding all six pages torn from a diary. These provide crucial backstory and are often hidden in plain sight.

• Page 1: In the study, on the small table next to the armchair.
• Page 2: In the kitchen, pinned to the corkboard next to the cellar entrance.
• Page 3: In the library, tucked inside the book titled 'Ode to Stasis' on the second-floor shelf.
• Page 4: In the master bedroom, on the nightstand beside the bed.
• Page 5: In the garden shed, sitting on top of a stack of old newspapers.
• Page 6: In the attic, resting on a wooden crate near the dusty telescope.

How to Get All 3 Antique Maskstag

The Masquerade achievement is awarded for finding three distinct antique masks. Each is tied to a small environmental puzzle.

• The Wooden Mask: Found in the garden shed. You must use the crowbar (found near the rusted wheelbarrow) on the loose floorboard in the back-right corner.
• The Porcelain Mask: Located in the library. After solving the grandfather clock puzzle, a secret compartment opens at its base containing this mask.
• The Gilded Mask: This is in the attic, inside the large locked trunk. The key to this trunk is found inside the music box after you repair it.

Locating the 5 Faded Photographstag

For the Photographer achievement, you must collect five old photographs. These are essential for understanding the narrative and for unlocking one of the secret endings.

• Photograph 1 (The Couple): Inside the locked desk drawer in the study.
• Photograph 2 (The Child): In the secret cellar, on a wine barrel.
• Photograph 3 (The House): On the mantelpiece above the fireplace in the main hall.
• Photograph 4 (The Garden): Pinned to the wall inside the greenhouse at the back of the garden.
• Photograph 5 (The Parting): This is the most hidden one. In the attic, look through the telescope and focus on the constellation drawn in the diary. A drawer on the telescope's base will pop open, revealing the final photo.

03

Puzzle & Challenge Achievementstag

These trophies are awarded for solving specific, optional, or particularly tricky puzzles within the house. They test your observation and logic skills beyond the main story path.

How to Crack the Safetag

Unlocking Master Thief requires opening the large, ornate safe in the master bedroom. The combination is not a single number but a sequence of clues found within the room itself.

1. Examine the calendar: The date circled in red is the 18th. This is your first number: 18.
2. Count the silver lockets: On the vanity table, there is a jewelry box. Open it and count the silver lockets inside. There are four. This is your second number: 4.
3. Check the grandfather clock: Note the time the clock in the hallway stopped at when you first entered: 9 o'clock. This is your final number: 9.

The final combination is 18-4-9. Enter it into the safe dial to open it and claim your achievement.

How to Fix the Music Boxtag

To earn A Familiar Tune, you must repair the music box in the master bedroom. This requires finding three missing Cylinders, each hidden in a different era of the house's memory.

• Cylinder 1 (Lullaby): Found in the child's nursery, a room accessible from the second-floor hallway. It's sitting on the rocking horse.
• Cylinder 2 (Sonata): This is your reward for solving the piano puzzle in the music room. Play the sequence noted on the sheet music (C-E-G-C) to open a hidden drawer in the piano.
• Cylinder 3 (Discord): Located in the secret cellar. It's on a shelf behind a stack of wine bottles that you must knock over.

Once you have all three, return to the music box and place them in the correct slots. The music will play, unlocking the achievement and revealing the key to the attic trunk.

04

Miscellaneous & Hidden Achievementstag

This category contains achievements for performing specific, often strange, actions that are easy to miss. They reward curiosity and experimentation.

• Introspection: In the main hallway, there is a large, clouded mirror. Simply stand still and stare into it for a full 60 seconds without moving. The screen will distort slightly, and the achievement will pop.
• A View to the Past: In the attic, after finding the final photograph, look through the telescope again. This time, point it at the old oak tree in the garden below. Keep it focused for about 15 seconds to trigger a brief visual flashback and the achievement.
• Played Out: In the music room, interact with the piano after you've already solved the puzzle. Instead of playing the required tune, play the C key twenty times in a row. This will unlock a dissonant chord and this hidden trophy.
• Water the Plants: Find the watering can in the garden shed. Fill it with water from the rain barrel outside. Go to the greenhouse and use the watering can on the dead, withered plant in the corner. It won't revive, but your effort will be rewarded with this achievement.

05

Secret & Ending-Related Achievementstag

Momento has three distinct endings, each with its own achievement. Your final actions in the game determine which one you receive. Crucially, you cannot get all three ending achievements in a single playthrough. You will need to reload your save before the final choice or play through the game multiple times.

Ending 1: The Loop (Default Ending)tag

Achievement: Déjà Vu

This is the standard ending that most players will get on their first run. To unlock it, you simply need to complete the game's final sequence without meeting the specific requirements for the other two endings.

1. Progress to the final room in the attic.
2. You will be presented with a pedestal.
3. Place the repaired Music Box onto the pedestal.
4. Watch the final cutscene. The cycle begins anew.

Ending 2: Breaking the Cycle (Good Ending)tag

Achievement: Freedom

This ending requires you to have found all five Faded Photographs. It represents understanding and letting go of the past.

1. You must have the Photographer achievement, meaning all 5 photos are in your inventory.
2. Progress to the final room in the attic.
3. When presented with the pedestal, ignore the Music Box. Instead, select the Photograph 5 (The Parting) from your inventory.
4. Place the photograph on the pedestal.
5. This triggers a different cutscene, one of acceptance and release, unlocking the achievement.

Ending 3: The Hidden Truth (Secret Ending)tag

Achievement: The Whole Truth

This is the most complex ending to achieve and requires finding all collectibles in the game: all 6 diary pages, all 3 masks, and all 5 photographs. It represents a full, unflinching confrontation with the past.

1. You must have unlocked Chronicler, Masquerade, and Photographer in the same playthrough.
2. Progress to the final room in the attic.
3. Before interacting with the pedestal, go to the corner of the room where a single floorboard is slightly ajar. Because you have all the collectibles, you will now be able to interact with it.
4. Pry open the floorboard to find a single, Tarnished Locket.
5. Place this Tarnished Locket on the final pedestal.
6. This triggers the secret ending cutscene, which reveals the complete story behind the house's tragedy and grants you the final achievement.

06

Achievement Hunting FAQtag

What is the hardest achievement to get in Momento?

The hardest is undoubtedly The Whole Truth. It requires meticulous exploration to find every single collectible in the game (diaries, masks, and photos) in a single run to unlock the final item needed for the secret ending.

Can you get all achievements in one playthrough?

No, it's impossible. The three ending achievements—Déjà Vu, Freedom, and The Whole Truth—are mutually exclusive as they depend on the final item you place. You'll need to strategically save before the final choice or play through the last chapter three times.

Do I need to restart if I miss a collectible?

Momento has no chapter select, so if you pass a point of no return (like leaving the main house for the final attic sequence) and have missed a collectible, you will need to load an earlier save or restart to get it.

07

A Final Reflectiontag

Achieving 100% completion in Momento is about more than just ticking boxes; it's about fully engaging with the game's environmental storytelling. Each collectible and hidden puzzle you solve adds another layer to the tragic, fragmented narrative. The multiple endings reward this deep exploration, transforming the game from a simple ghost story into a poignant reflection on memory, grief, and acceptance. Good luck on your hunt.
