About Opus Castle Chapter 4

Opus Castle Chapter 4 continues the investigation into the castle’s tragedy, taking you into its darkest secrets. Time warps, making the past appear as if it were the present, while visions of those who lived and died in the castle become unavoidable. The castle reveals a consciousness of its own and reacts to your presence. Your investigation becomes personal, and each ghost you encounter has a story to tell or a warning to give.
