About this game

Hell didn’t end — it was merely asleep.

In Opus Building, the sequel to Opus Castle, you return to the shadows of São Paulo for a deeper, more dangerous, and more supernatural investigation. Blending psychological horror, narrative exploration, and esoteric elements based on real events, this chapter places you at the center of a new mystery involving secret cults, demonic rituals, and one of Brazil’s most infamous tragedies: the fire at the Joelma Building.

A new story unfolds with investigative journalist Helena Meirelles, hired to write a feature about the building’s revitalization. What she doesn’t know is that she’s being used by a cult seeking the second key to the Ark of Solomon — a hidden artifact of immense power tied to the 1974 fire.

As Helena digs deeper into her story, she’s pulled into a temporal journey that takes her into the past, reliving the hours before the tragedy — and into a space where hidden forces are about to tear the Veil between worlds.

Key Features:

  • A setting inspired by the Joelma Building
    A dense and symbolic reconstruction of one of Brazil’s most iconic locations, shifting between the physical, the spiritual, and the infernal.

  • Narrative exploration across layered timelines
    Travel between 1974, the present, and a distorted spiritual dimension where time folds in on itself — investigate, decode, and survive.

  • Psychological and spiritual horror
    Demonic entities, whispers, illusions, and ever-changing environments create an atmosphere of dread built on tension and discovery.

Inspired by real events. Powered by the unknown.

Opus Building expands the universe introduced in the first game, taking historical horror to new spiritual depths. Get ready to face your own fears — and uncover what was truly sealed behind the doors of the 13th floor.
