Aberratic Reveals New Gameplay Trailer for Symbiosis and Opens Sign-Ups for First-Ever Community Playtest

Can You Survive Sigma Century?

In solo or co-op play, Symbiosis plunges you into the hostile, procedurally generated alien world of Sigma Century. You take on the role of an A.S.T.R.A., an elite fighter dispatched to protect a scientific mission, until a mysterious electromagnetic pulse brings your ship crashing down. Stranded, you’ll need to scavenge resources, establish fortified bases, master both ranged and melee combat, and explore diverse, ever-deadlier biomes to uncover the truth of what happened to the scientists before you.

But survival won’t be easy. The scientists’ imported technologies have left their mark, warping the local wildlife into relentless threats. Every step deeper into Sigma Century pushes you closer to hostile creatures, environmental hazards, and secrets that might hold the key to your escape.

Key Features

Think of Symbiosis as a hybrid between 7 Days to Die and The Riftbreaker. 

• Base Defense – Your presence and your technology emit electromagnetic pollution that draws increasingly aggressive waves of creatures. Build a stronghold and fight for your survival.
• Exploration – Traverse a wide variety of alien biomes that grow harsher and more treacherous the further you venture from your crash site. Endure heavy storms, sand-blasting winds, hostile plants, and dangerous creatures lurking in the wild.
• Base Building – Gather resources to construct and expand your fortified base. As you advance, unlock more sophisticated defenses and automated systems to hold back the planet’s hostile forces.
• Boss Battles – To escape Sigma Century, you’ll need to customise your role, upgrade your gear, and coordinate your playstyle with friends to overcome colossal symbiotic bosses.

A Call for Survivors

The new gameplay trailer gives players their best look yet at the harsh environments, base-building mechanics, and heart-pounding battles against the planet’s monstrous inhabitants. But Aberratic doesn’t just want players to watch, they want them to join the fight.
