Nocturne: Mystery Stories

Every account has a missing piece. Can you find it?

Nocturne is a story-based mystery game for players who enjoy examining evidence, comparing accounts, and working toward a final accusation.

FOUR BUILT-IN CASES
Investigate a museum disappearance, a letter from an old port, a mystery beyond orbit, and secrets behind a theater curtain. Each case has its own characters, clues, and solution.

FOLLOW THE EVIDENCE
Move through a briefing, evidence collection, questioning, a final accusation, and a recap. Pin clues to your investigation table and connect details to build your theory.

PLAY SOLO OR IN A ROOM
Built-in solo cases work offline. With an internet connection, create a room, invite friends with a room code, choose roles, and coordinate the investigation. Room features include text chat and optional microphone voice chat.

CHOOSE YOUR LANGUAGE
Switch between English and Chinese. Built-in phase summaries and clue readings are available in both languages. Selected characters also have recorded monologues; character voice coverage varies by case and language.

NO REGISTRATION REQUIRED
Play with a guest identity. Manage your display name and delete guest data from the in-app profile panel.

Multiplayer features require an internet connection. Microphone access is requested only when you choose to join voice chat.
