Beginner guide

Listen to KEY. The AI companion flags scannable objects and frequencies. If a room feels “done,” open the investigation log and look for greyed prompts — you often missed a sonar band or a two-sided document.

Vault early. Many achievements tie to deduction count. Link clues as soon as the board unlocks new nodes instead of hoarding everything for the finale.

Manage sanity. Corruption visuals are tempting to rubberneck — short looks are fine, marathon staring feeds the bad ending trajectory. See the sanity guide for chapter callouts.

Demo scope. Chapters 1–2 are fully documented on this wiki. Later chapters will grow after release; bookmark the walkthrough index.

FAQ

How do I unlock Thanks Key?

Have KEY analyze 25 distinct clues. Chapters 1 and 2 of the demo contain more than half of them if you scan thoroughly.

Where is the quartz alloy?

Near the occult book pages on the shelves in May's house. Scan it on the Mineral sonar frequency when KEY unlocks that step.

I missed a clue — can I go back?

Most demo areas allow free backtracking inside the chapter. If a door locks, reload an earlier save if available.

Hardest achievement in the demo?

Thanks Key or full frequency coverage — both reward slow, methodical scanning.

Does this wiki spoil the full game?

Chapters 3–7 are placeholders until release. Demo content is described in detail.
