Overview

About this game

Atheris is a tense sci-fi horror adventure set aboard a research vessel drifting through deep space. After a violent awakening from cryosleep inside the decaying Atheris, Dr. Elhias Roth must piece together his memories, rediscover his purpose, and—above all—avoid suffering the same fate as the rest of the crew.

The game blends tense exploration, environmental storytelling, and a claustrophobic design inspired by classic sci-fi. Every decision matters, and your ability to manage combat, scarce ammunition, and your own composure will determine whether you escape… or become just another corpse floating through space.

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.
