Indie studio Aberratic has revealed a major milestone for its upcoming sci-fi survival action RPG Symbiosis, confirming that the game’s first public playable demo launches on Steam on January 26, 2026. The announcement arrived alongside a brand-new gameplay trailer unveiled during the Unity Games Awards, offering players their most intense look yet at the fight for survival on the hostile alien world of Sigma Century.
The demo marks a crucial step toward Symbiosis entering Steam Early Access in early 2026, giving players a hands-on taste of its co-op base building, escalating swarm combat, and tactical survival systems. Players can now wishlist Symbiosis on Steam to stay informed as more demo details are revealed in the coming weeks.
A First Look at Symbiosis Gameplay
The latest Symbiosis trailer highlights the game’s core pillars: teamwork, preparation, and survival under pressure. Whether played solo or in co-op, Symbiosis challenges players to scavenge scarce resources, construct fortified bases, and prepare for relentless waves of hostile alien creatures.
Every defensive choice matters. Walls, turrets, and automated systems must be carefully placed, as your growing technological footprint draws increasingly aggressive swarms. The longer you survive, the deadlier the planet becomes—forcing squads to adapt or be overrun.
Crash-Landing on Sigma Century
In Symbiosis, players take on the role of an A.S.T.R.A, an elite guardian sent to protect a scientific expedition on Sigma Century. Disaster strikes when a mysterious electromagnetic pulse downs your ship, leaving you stranded on a procedurally generated alien world filled with unknown dangers.
As you explore the planet, you’ll uncover traces of the expedition that came before you and piece together what went wrong. Survival depends on mastering both melee and ranged combat, adapting to hostile environments, and pushing deeper into biomes that grow more unpredictable and unforgiving with every step.
Sigma Century itself has been irrevocably changed. Human technology has polluted the ecosystem, mutating the planet’s wildlife into aggressive, territorial horrors determined to reclaim their world.
Survival Built Around Swarms and Strategy
Unlike traditional survival games, Symbiosis places heavy emphasis on base defense against escalating swarms. Your advanced equipment emits electromagnetic pollution, acting as a beacon for hostile lifeforms. The stronger your base becomes, the more intense the attacks will be.
Success requires strategic planning, smart resource management, and close coordination—especially in co-op play—where each player’s role can mean the difference between survival and annihilation.
