Achievements Guide

Track the 15 Steam achievements with spoiler boundaries for progression, optional interactions, and completion tasks.

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

Progression achievements

Several achievements naturally unlock as you learn the machine, visit key locations, and advance the investigation.

Optional interaction achievements

Some objectives reward unusual experiments or persistence. Save detailed triggers until you are comfortable with spoilers.

Completion achievements

Location and all-scenes achievements are best handled after the main mystery, when spoilers no longer undermine the deduction path.
