Opus Castle: Chapter IV
About this game
Chapter 4 invites you into the heart of the castle's darkest secrets. Time begins to distort, showing the past as if it were the present. Visions of those who lived—and died—there become inescapable. The castle begins to reveal its own consciousness, reacting to your presence. Your investigation into the tragedy becomes personal, and each ghost you encounter has a story to tell—or a warning to deliver.
