100 Percent Checklist

Use a structured completion pass for rooms, scenes, hidden interactions, and remaining Steam achievements.

Spoiler note: this page keeps direct late-game answers separated from early investigation guidance.

Finish the mystery first

A first solve gives context for cleanup and prevents the checklist from becoming an answer key too early.

Audit rooms and scenes

Review every room for at least one known memory, then compare missing time or person combinations.

Confirm hidden objectives

After visible achievements are complete, investigate optional machine interactions and story-adjacent secrets.
