About this add-on

Evolution had its chance. Now it’s our turn.

In Stellaris: BioGenesis, step into the role of a master geneticist, sculpting the galaxy to your design with living ships, engineered ecosystems, and enhanced species.

The line between creator and creation blurs as you unravel the mysteries of life itself, unlocking the power to forge a living weapon capable of reshaping the galaxy – or devouring it.
