About This Game

YOU WERE NOT BROUGHT HERE BY ACCIDENT.

Mira Voss calls her mother. A scream cuts through the line.

The next thing she remembers is waking beneath the fluorescent lights of Vossarium: A sealed neurological research facility that already has a file on her.

To get out, Mira must make her way through abandoned research wings, restore failing systems, survive the facility's experiments and avoid the Guardian still roaming its halls. Along the way, she begins uncovering records of patients who came before her, and evidence that the Voss name has been connected to this place for far longer than she knew.

But something else is growing inside Vossarium.

Somneth.

It runs through walls, machines and forgotten experiments like a living infection. The deeper YOU intentionally interact with Somneth, the more unstable reality becomes. Rooms grow a vile purple. Memories become unreliable. Things begin reacting to choices that shouldn't be understood.

And eventually, something inside Vossarium may notice that Mira isn't the only one making them.

VOSSARIUM is a first-person psychological horror adventure combining exploration, environmental puzzles, survival horror and turn-based encounters inside a facility that becomes increasingly impossible the deeper you go.

EXPLORE VOSSARIUM

Navigate interconnected laboratories, patient wings and experimental spaces filled with environmental storytelling, hidden areas and secrets. What begins as an abandoned research facility gradually becomes something far stranger.

SOLVE EXPERIMENTS, NOT JUST PUZZLES

Interact with terminals, machinery, cameras and experimental equipment through a wide variety of puzzles and minigames. Observation and understanding the environment are often more important than simply finding a key.

SURVIVE THE GUARDIAN

You are not alone in the facility. Hide, manage your surroundings and learn how Vossarium's most persistent threat behaves. Sometimes running is the right answer. Sometimes it isn't.

FACE WHAT YOU CAN'T RUN FROM

Certain encounters pull Mira into stylized turn-based battles where timing, composure and defensive mechanics matter as much as attacking. Each enemy can introduce its own rules, and not every confrontation needs to end the same way.

WATCH REALITY COME APART

Impossible architecture, shifting environments and non-Euclidean spaces gradually break the rules established around you. Some places in Vossarium simply could not exist.

YOUR ACTIONS LEAVE A MARK

Optional discoveries, hidden fragments and decisions throughout the facility can change encounters, reveal new information and lead Mira down different paths.

FIND YOUR WAY OUT... OR SOMETHING ELSE

Vossarium contains multiple routes and endings, including secrets intended for players willing to question what the game tells them.

Some things were buried for a reason.

Mature Content Description

The developers describe the content like this:

Some scenes in Vossarium are not for the faint of heart. Some scenes portray murders or hallucinations which can be quite shocking.
