Summary pulled directly from Steam - Some text may only be applicable to Steam platform

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.

Players can look forward to trying out the entirely new Lithoid play style that focuses on mineral production, relentless colonization of even the most marginal worlds, and refusing to cede an inch of your empire - for sedimental value. The Lithoids Species Pack includes:

Unique Mechanics for Lithoid Empires
15 New Portraits of Lithoids and 1 of a Lithoid robot
New Mineral-based Ship Models
New voice pack
