About Symbiosis Demo

In the far future, the Centralized Human Republic ordained that every colony relinquish all control to them. This sparked pockets of rebellion around the galaxy.

To deal with the constant tide of new inmates, the C.H.R. gives the most gifted ones a choice: serve years in an overcrowded facility, or work for them reclaiming planets lost to dangerous experiments.

Players take control of those selected few and fight, or die trying...

Defend The Core at all costs against the hundreds of mechanical hybrids invading at night. Search for resources, automate their collection, and develop a powerful defence system with rows of walls and turrets. Do not forget to keep your electrical system up and running.

Venture deep in the fog in search of new possible outposts. Fight rogue enemies and collect their genetic material to unlock new skills and empower your character. Each character is unique, learn to make the best out of their kit.

Each night, the swarm gets more violent. You need to work quickly to keep up; bringing friends might be a good idea. You might not be able to work your way past the evolving enemies at first, but each game will help you learn.
