The Mermaid Mask All Achievements: The Ultimate Guide to 100% Completion

Diving into the atmospheric depths of a maritime mystery requires more than just a keen eye for clues; it requires the dedication of a completionist. If you are looking to master every corner of this underwater adventure, our guide to The Mermaid Mask all achievements is your definitive roadmap. Unlocking all 21 trophies in the game is a journey through hidden compartments, complex character interactions, and the eerie silence of a deep-sea vessel. By following this walkthrough, you will ensure that no secret remains submerged and that you successfully track down The Mermaid Mask all achievements in a single, efficient playthrough.

Overview of The Mermaid Mask Achievement System

The achievement list in The Mermaid Mask is designed to reward both progression and curiosity. While roughly a third of the trophies will unlock naturally as you navigate the narrative, the remaining two-thirds require deliberate action. Some involve interacting with specific environmental objects, while others demand that you exhaust dialogue options with the game's colorful cast of suspects.

According to community reports, the game does not currently feature a "chapter select" that allows for easy cleanup of missed trophies. This makes it vital to know which items are missable before you transition between major story beats. Players have noted that the "point of no return" often occurs when moving between the submarine's various decks or completing major interrogation sequences.

Achievement Categorization

To help you organize your hunt, we have categorized the 21 achievements into three primary groups: Story Progression, Exploration & Interaction, and Completionist/Clue Gathering.

Story-Related Achievements (Unmissable)

These achievements are the backbone of your journey. As long as you reach the credits, you will earn these without any extra effort. They serve as milestones for your progress through the investigation.

• Reach Chapter One: This is awarded immediately upon completing the Prologue. The Prologue serves as an introduction to the controls and the initial mystery on land before you board the submarine.
• Unlock the Captain's Cabin: During Chapter 1, you will need to locate the Eyeball Key. Using this key to gain access to the Captain's Office will trigger this unlock.
• Complete the Game: Awarded once the final cutscene rolls and the mystery of the Mermaid Mask is solved.

Exploration and Environmental Achievements

This is where many players miss out on The Mermaid Mask all achievements. The developers have hidden several trophies behind small, seemingly insignificant objects. You must be proactive in clicking on everything in the environment.

The Statue and Photo Hunt

One of the more complex exploration achievements requires you to examine four specific items across different locations. Missing one of these early on can lock you out of the achievement for the rest of the run.

1. Town Square Statue: Located outside the Inn during the Prologue. Look for the serpent statue before you board the submarine.
2. Mess Hall Statue: Another serpent statue, this one is located in the submarine's Mess Hall near a lockable cabinet.
3. Newspaper Page: Found within the living quarters; ensure you read the text fully.
4. Family Photo: Usually found in one of the private bunks; examine the back of the photo if possible.

Submarine Mechanics and Puzzles

The submarine itself is a puzzle box. Two specific achievements are tied to the vessel’s hardware:

• Pull both levers on the submarine's Control Panel: When you reach the Control Room, interact with the main panel. You must pull both the red and yellow levers. Player experience suggests doing this as soon as you enter the room to avoid story triggers that might lock the panel.
• Examine the dark hole in Dr. Zephyr's bookcase: This is a multi-step process. First, you must complete the bottle puzzle within the Dream Chamber. Once solved, look at the bookshelf above the puzzle area. There is a small gap or "dark hole" between the books. Clicking this gap grants the trophy.

Character Interaction and Dialogue Achievements

The Mermaid Mask is a character-driven mystery. To earn The Mermaid Mask all achievements, you must be a social butterfly—or at least a very persistent interrogator.

The Locket and the Magazine

In the Bunk Room shared by Symmetry and Sinthia, there are two major achievements to snag.

• Open the Golden Locket: First, speak to both Symmetry and Sinthia to establish their relationship. Afterward, ask Symmetry specifically about her Golden Locket. You will then be prompted to inspect it. Rotate the object and find the latch to open it.
• Read through the Movie Magazine: This is found in the same Bunk Room. You cannot just click on it; you must flip through every single page of the magazine to trigger the achievement.

Advanced Interrogations

As the plot thickens, your case file becomes your greatest weapon.

• Talk to Sinthia about the Case File: Once you have gathered enough evidence to form the Case File clue, present it to Sinthia during a dialogue sequence.
• Talk to all suspects about the HER painting and the Underwater Photo: This is a tedious but necessary task. Every time you find a major piece of visual evidence, like the "HER" painting or the "Underwater Photo," you must cycle through every available character and ask them about it.

Hidden Secrets and "Work in Progress" Discoveries

There are several achievements that the community is still documenting in detail. Based on current player experience, here is how to handle the more obscure entries in The Mermaid Mask all achievements list.

The "Boggy" and the Cephalopod

The developers included a few "easter egg" style achievements that reward unconventional thinking.

• Examine the Boggy head in the Cabinet of Curiosity: The Cabinet of Curiosity is a treasure trove of oddities. Look for a mounted head that looks out of place (the "Boggy" head) and interact with it.
• Use the incorrect term for the six-legged cephalopod: This usually occurs during a dialogue choice or while examining a biological specimen. When given the option to name the creature, choose the scientifically inaccurate term.

The Mystery of the Clues

There are two achievements related to clue gathering: "Find all the clues" and "Find ALL the clues." While they sound identical, the capitalization suggests a distinction between mandatory story clues and optional environmental lore. To ensure you get both, you should interact with every readable document, including Zephyr's letters and Mariana Moon's secret Dictaphone.

Strategic Tips for 100% Completion

To make your hunt for The Mermaid Mask all achievements as smooth as possible, keep these tips in mind:

1. Examine everything twice: Many objects in the game have secondary interactions. If you click an object and a dialogue box appears, click it again to see if your character has more to say.
2. The "Checklist" Method: Before leaving any room, check your inventory and your clue log. If you haven't found a collectible in a new area, chances are you've missed a drawer or a shelf.
3. Talk First, Act Second: Before progressing the story by using a key item (like the Eyeball Key), make sure you have spoken to every NPC about your current inventory items.
4. Save Often: Since there is no confirmed chapter select, keeping multiple save files at the start of each chapter can save you hours of replaying if you miss a specific interaction like the Movie Magazine.

The Completionist's Checklist

As you near the end of the game, verify that you have completed these specific, often-overlooked tasks:

• Watched all three film reels on the Film Projector.
• Read the service record label on the Fixed Compass.
• Reunited the two Handheld Radios (requires inventory management).
• Removed the bandage from Cornelius Cane.
• Read through every single one of Zephyr's letters.
• Discovered Mariana Moon's hidden Dictaphone.

By following this structured approach, The Mermaid Mask all achievements will be yours. The game rewards the patient detective who treats the submarine not just as a setting, but as a puzzle to be solved. Whether it's the thrill of finding the "Boggy" head or the satisfaction of opening Symmetry's locket, each achievement adds a layer of depth to the overarching narrative.
