A Mask’s Tale is an investigation and suspense game that takes place in an alternative version of the city of São Paulo. In this dystopian reality, people are forced to wear masks, hiding their faces and identities.

During the story, the player must take on the role of a retired detective, who now works as a craftsman, creating and repairing masks. However, he suddenly finds himself in the middle of an ideological war between those who want to abolish the use of masks, known as "The Unmasked" and those who defend their use.

Now, it's up to the Craftsman to rescue and accumulate clues, while at the same time trying to investigate and solve a crime.
