Stellaris is Paradox Development Studio's space grand strategy masterpiece — a game of boundless scope that tasks you with guiding a custom-designed alien civilisation from its first steps into space to galactic dominance or destruction. Design your species from biology and psychology to homeworld and government type, then explore a procedurally generated galaxy packed with anomalies, ancient ruins, precursor civilisations, wormholes and the terrifying extradimensional threats lurking at the edge of the known universe.

Key Features: • Custom species design — biology, psychology, government, homeworld and civics all yours to define • Procedural galaxy — anomalies, ruins, precursors, wormholes and cosmic threats every playthrough • 4X grand strategy — explore, expand, exploit and exterminate across a living galaxy • Dozens of civilisation interactions — federations, wars, trade, uplift or extermination
