Mater Abyss is a first-person psychological horror experience presented as found footage.

In July 1993, an entire family vanished without a trace.
Weeks later, a videotape was found inside their apartment.

This is that recording.

You play as Agata, a psychology student sent to document the Romano family’s home.
What begins as a routine investigation slowly turns into something else.

The apartment does not remain the same.
Spaces shift. Sounds linger.
Some things shouldn’t be there.

And at some point… you may realize you are no longer alone.
