Complete Achievement Guide for The Incident at Galley House

The Incident at Galley House has 15 Steam achievements, including 5 hidden ones. Some unlock naturally through story progression, while others require specific actions like finding hidden scenes, completing all content, or discovering special codes. This guide covers every achievement with detailed unlock instructions, organized by category for easy reference.

Story Achievements (Automatic)

These achievements unlock through normal story progression. You cannot miss them if you complete the game.

Seance

How to unlock: View your first memory scene.

This is the first achievement most players earn. Simply enter any valid code into the memory machine and watch the resulting scene. The earliest code you can enter will trigger this achievement. It is impossible to miss — the moment you start investigating, you will unlock Seance.

Estimated time: Under 5 minutes from starting the game.

A Shocking Revelation

How to unlock: Uncover a major truth about the incident.

This unlocks at a specific story milestone when you discover a significant plot revelation. It happens naturally as you progress through the main scenes. You do not need to do anything special — just keep investigating and the revelation will come. The achievement is tied to a fixed story event, not to a specific code or deduction.

Estimated time: 3-5 hours into the game.

Still Alive

How to unlock: Identify a character who survived the incident.

You must correctly identify at least one character whose fate is "Alive" rather than "Deceased." Eve Dauer (Person 9, Goose) is the most obvious surviving character — she is the only confirmed survivor from the 1936 gathering. When you confirm her identity and fate on the deduction board, this achievement unlocks.

Strategy: Focus on identifying Eve early. Listen for her name in dialogue — Helen frequently addresses her by name. Once you can confidently match Eve's voice to Person 9, submit the identification on the deduction board.

Estimated time: 4-6 hours, depending on how quickly you identify characters.

Deduction Achievements

These achievements are tied to the deduction system and investigation mechanics.

Death Note

How to unlock: Mark a character's death on the timeline.

When you determine that a character has died, mark their death on the chronological timeline. The first time you do this, you earn the Death Note achievement. You do not need to be correct — simply marking any death triggers the achievement, even if your answer is wrong.

Strategy: Mark a death as soon as the timeline is available, even if you are not confident. The achievement triggers on the first marking regardless of accuracy, and you can always change your answer later.

Estimated time: 2-4 hours, as soon as the timeline becomes available.

Machine Supervisor

How to unlock: Restore the machine's power for the first time.

The first time the machine loses power, find the correct procedure to restore it. The solution involves examining the machine's physical components and following a specific sequence. Check the area around the machine for interactive elements — switches, cables, and power indicators. The first restoration is designed to be straightforward and teach you the process.

Strategy: When the machine loses power, immediately examine the environment. Do not try to enter codes — the machine will not respond until power is restored. Look for Sam Moors' assistance in present-day scenes.

Estimated time: 1-2 hours, at the first power loss event.

Technical Engineer

How to unlock: Restore the machine's power a second time.

After the second power loss, restore power again. This restoration is more complex than the first and requires you to locate additional resources within the D&M facility. Pay attention to clues from earlier scenes about the machine's power system.

Strategy: The second restoration requires finding resources beyond the immediate machine area. Explore the D&M facility and listen for Sam Moors' technical guidance. Scenes you viewed before the power loss may contain relevant clues about the power system.

Estimated time: 4-6 hours, at the second power loss event.

Researcher

How to unlock: Unlock a significant number of memory scenes.

This achievement is cumulative — you earn it after unlocking a threshold number of scenes. Keep entering codes and discovering new scenes throughout your investigation. You do not need to find every scene, just a substantial portion. Most players earn this naturally during their investigation without specifically pursuing it.

Strategy: Enter codes systematically to maximize your scene discovery rate. Use the keyword search tool to find related scenes after each new viewing. The more scenes you unlock, the faster you approach the threshold.

Estimated time: 5-8 hours, depending on investigation thoroughness.

Exploration Achievements

House Tour

How to unlock: Discover all 16 locations in Galley House.

You must discover and label every room across all three floors of Galley House. This requires entering codes that reference all 16 location codes. The location guide provides the complete list of room codes and how to find them.

Strategy: Enter codes systematically for each two-letter room code. Ground-floor rooms (EN, LI, KI, DI, QU, ST) are discovered early. Upper-floor rooms (VI, HE, OS, CH, GA, AT, CO, WI, LA, BA) require later scenes. Wintercote (WI) is typically the last room discovered.

Estimated time: 3-6 hours with systematic exploration.

Secret Achievements (5 Hidden)

TYPE HELP

How to unlock: Enter the TYPE HELP code into the machine.

This is a reference to the original browser game that inspired The Incident at Galley House. Type "TYPE HELP" (or "TYPE-HELP") as a code into the machine. This triggers a special meta-scene and awards the achievement. It can be done at any point during your investigation — you do not need to discover it through clues.

Strategy: Enter TYPE-HELP as soon as you start playing. The achievement pops immediately, and the meta-scene provides interesting context without spoiling the main mystery. This is one of the easiest hidden achievements to earn.

Full House (Hidden)

How to unlock: Label all 16 locations in Galley House.

Similar to House Tour but specifically requires correctly labeling each location with its two-letter code on the deduction board or location interface. If you have earned House Tour, you likely have the information needed for Full House — you just need to confirm each label.

Strategy: After earning House Tour, review each discovered location and ensure its two-letter code label is correctly submitted. The most commonly missed label is Wintercote (WI). Double-check all labels and submit them on the deduction board.

Hallucination (Hidden)

How to unlock: View the hidden hallucination scene.

This requires entering a specific hidden code that is not part of the normal scene sequence. The code references a supernatural or psychological scene that exists outside the main timeline. Finding this code requires thorough investigation and attention to subtle clues.

Strategy: Focus on Chapel (CH) scenes — the supernatural center of Galley House. Search for keywords like "hallucination," "vision," and "specter" in the dialogue transcripts. If you cannot find the code through investigation, request hints from the progressive hint system. See the hidden scenes guide for more detailed instructions.

Inciting Incident (Hidden)

How to unlock: Discover the event that started everything.

This achievement is tied to the meta-plot. You must uncover the specific event or revelation that sets the entire incident in motion. It requires connecting information from both timelines and making the right deduction about the overarching cause.

Strategy: Complete all or nearly all scenes from both Part 1 and Part 2 before attempting this deduction. The meta-plot requires evidence from both timelines. Search for recurring themes across Part 1 and Part 2 using the keyword search tool. The deduction guide explains the approach in detail.

Not Over Yet (Hidden)

How to unlock: Reach the secret post-credits content.

After completing the main story, do not stop playing. Continue investigating after the apparent conclusion to discover additional content. This achievement rewards players who keep exploring beyond the expected endpoint.

Strategy: When the story appears to end, continue entering codes and operating the machine. New scenes become available after specific story milestones. The post-credits content provides essential meta-plot information and is required for the Spectronoeticist achievement.

Completion Achievement

Spectronoeticist (Hidden)

How to unlock: View every single memory scene in the game.

This is the hardest achievement in The Incident at Galley House. You must find and view all scenes including the main sequence, hidden scenes, and special scenes. This includes:

• All 26 Part 1 (Past) scenes
• All Part 2 (Present) scenes
• Scene 00 (the prologue)
• The TYPE HELP meta-scene
• The Hallucination scene
• All +64 hidden scenes
• All post-credits content scenes
• Any other hidden or optional scenes

Strategy: Use the complete scene codes list as a checklist. Systematically enter each code and mark it off after viewing. Use the keyword search tool to find scenes you might have missed. Request hints for any gaps in your progress. See the dedicated Spectronoeticist achievement guide for a detailed completion strategy.

FAQ

Can I earn all achievements in a single playthrough?

Yes, all 15 achievements can be earned in a single playthrough. The game has no mutually exclusive achievements or choices that prevent you from earning certain ones. Follow the roadmap above for the most efficient completion.

Does using hints affect achievement unlocking?

No. There is no penalty for using the progressive hint system, and hint usage does not prevent any achievement from unlocking. You earn all achievements the same way whether you use zero hints or all of them.

What is the rarest achievement?

Based on player behavior, Spectronoeticist is likely the rarest achievement because it requires 100% scene completion, which demands thorough investigation and finding all hidden scenes. Most players complete the main story without viewing every optional scene.

Can I earn achievements while offline?

Steam requires an internet connection to sync achievements to your profile. However, the achievement triggers will still fire while playing offline, and they will sync to your profile the next time you connect to Steam.
