Opus Castle VR is a 3D horror, adventure and mystery game with a narrative based on the true and tragic story of the small castle on Apa Street, located in the city of São Paulo, Brazil.

In the game, the player must explore the secret rooms and environments of the Castelinho, encountering the famous supernatural apparitions, noises from nowhere and laments from spirits of the past. In the meantime, you wake up in one of the rooms next to a body riddled with bullets. Suicide or murder?

Opus brings a basic mechanic for exploration, which focuses more on the narrative, which will be divided into 6 chapters, with 5 different story variations for each one.
