Stellaris: Lithoids Species Pack is now available DRM-free.
The Lithoids Species Pack features a selection of new rock-based species portraits and ship models for players who take nothing for granite and are looking to unearth a more grounded civilization. Lithoids are a bigger and boulder species type made entirely of sapient rock who eat minerals for sustenance, are long-lived, and can colonize in almost any environment.
