About

A haunted past buried beneath the waves

In Dark Mass, players take on the role of Alice, a deep-sea explorer who, alongside her brother Reed, stumbles upon the wreckage of an ancient ship. But beneath it lies something far more sinister—a manor lost to time, eerily untouched despite spending centuries in the abyss.

As Alice ventures inside, she soon realizes she is not alone. Something watches from the darkness. Trapped within the manor’s decaying halls, she must unravel the mysteries of its past, solve dark ritualistic puzzles, and face the horrifying truth that binds her to this place.

With fully voiced dialogue, immersive underwater physics, and a haunting narrative, Dark Mass promises a terrifying descent into the unknown, where every choice matters and survival is anything but guaranteed.
