A mother and her child have disappeared without a trace. As Agata, assigned to document the case, you enter the apartment where they were last seen. Your task is simple: observe, record, and gather every detail. But the longer you stay, the more the house begins to change. Mater Abyss is a first-person psychological horror experience with a found footage aesthetic, built on atmosphere, tension, and observation. Your camera’s zoom is not just a tool to look closer… it may reveal what should not be seen. Explore shifting environments, document clues, and confront a presence that may never fully reveal itself. Some things do not want to be found.
