Game Concept
A crime has been committed.
Each player takes on the role of a suspect and tries to uncover the culprit by analyzing clues and the statements made by the other characters.
No experience required. No host needed. Everything is designed so you can easily organize your game night and fully enjoy the experience with your guests.
The Mysterius Concept
An immersive ambient video drives the game forward, guides the players, reveals clues, and creates interactive moments that make the investigation more dynamic and realistic. It also allows the organizer to play and discover the outcome at the same time as the other participants.
Two Versions, Organizer’s Choice
- Guilty on a Mission: The guilty player knows their role from the start and creates suspicion throughout the investigation.
- Total Mystery: In this version, the culprit’s identity remains secret until the final reveal, even from the player portraying that character.
