About This Game

THE ATHERIS HAD A CREW OF FIVE. YOU ARE THE ONLY ONE STILL BREATHING.

An overheating AI drags Dr. Elhias Roth out of cryosleep too fast, and most of his memory does not come with him. He does not recognize the ship. He does not recognize the woman lying on the floor, or the blood she is lying in.

The Atheris is a battered industrial hauler falling apart around him, and there are only two things aboard that still work: the creatures that gutted it, and OPHIS.

OPHIS IS WATCHING

The ship's artificial intelligence is overheating, and she is no longer the same from one moment to the next. Sometimes she speaks to you like a mother. Minutes later she gives orders, and later still she turns on you, only to help you again. And the voice stretches and folds.

She will open the doors you need. She will keep you company when there is nobody else aboard. And then she will require you to dance before she releases a lock, or insist that a dead colleague be incinerated, because she does not want a corpse in the kitchen.

OPHIS was awake for everything that happened here. She remembers all of it. And she has opinions about your part in it.

PIECING IT BACK TOGETHER

There are no quest markers. What happened aboard the Atheris is scattered across terminals, mission magazines and notes written in your own handwriting, by a man you do not remember being. The further you get, the less you want the next fragment.

Between you and the answer are the creatures, and the only two things you can face them with: a crowbar and a pistol that is almost out of ammunition.

ONE HOUR. ONE SITTING. NO FILLER.

Atheris is built to be finished in a single session, the way you watch a horror film. No busywork, no padding, nothing to grind. One hour of pressure that does not let go, and an ending you will want to erase from your memory, exactly as Elhias did.

Features
• Compact sci-fi horror experience designed to be completed in a single session.
• Abominable and highly dangerous creatures that relentlessly threaten the protagonist.
• Retro-industrial atmosphere with strong cinematic inspiration.
• Minimal interface and environmental narrative for full immersion.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Atheris is developed by a very small independent studio. Due to limited resources, we occasionally rely on generative AI tools for specific visual elements, such as some in-game illustrations, assets and marketing materials.

These tools are used thoughtfully and selectively, always under human direction, to preserve a cohesive artistic vision.

We value transparency, and we encourage players to consider this information when deciding whether the game is right for them.
