You lead a civilization that has just gained the means to travel between stars. Each campaign unfolds in a procedurally generated galaxy, where you encounter alien societies, unfamiliar worlds, and unexpected events.
Send science ships to survey star systems and investigate anomalies, while construction ships build stations. Expand by developing planets and managing your empire’s resources and population.
Shape your civilization through its traits and policies, then choose how to deal with other empires through diplomacy, alliances, or war. Research technologies and design fleets as your influence grows; the game runs in real time with pause.
Players who praise Stellaris often enjoy building a distinct spacefaring empire and seeing its history unfold through unpredictable encounters, diplomacy, and conflict. Reviews also value the variety between campaigns, role-playing possibilities, and mod support. Many longtime players in this sample still describe the core game as compelling, while criticizing recent changes, late-game performance, and the cost of additional content.
Get ready to explore, discover and interact with a multitude of species as you journey among the stars. Forge a galactic empire by sending out science ships to survey and explore, while construction ships build stations around newly discovered planets. Discover buried treasures and galactic wonders as you spin a direction for your society, creating limitations and evolutions for your explorers. Alliances will form and wars will be declared.
Like all our Grand Strategy games, the adventure evolves with time. Because free updates are a part of any active Paradox game, you can continue to grow and expand your empire with new technologies and capabilities. What will you find beyond the stars? Only you can answer that.
Stellaris now includes the base game, three expansion packs, and a collection of digital goods.
Stellaris: Chart a vast, procedurally generated galaxy where every star system holds a new mystery to uncover or an alien civilization to encounter. Forge a unique empire: from your first warp jump to galactic domination, you decide whether the universe remembers you as a benevolent pioneer or a relentless conqueror.
Utopia: Unlock the full potential of your empire with this expansion focused on the evolution of society. Whether you're building mega-structures or ascending to a higher plane of existence, Utopia helps you create a future that’s as bright as the stars themselves.
Synthetic Dawn Story Pack: Take command of a Machine Empire and reshape the galaxy in your own image. Will you lead your mechanical creations to peaceful coexistence, or will the rise of synthetic life spell the end for organics?
Humanoids Species Pack: the most-played phenotype now gains more variety with unique civics and a new origin. Along with their own unique ship class, new portraits, and more, there’s never been a better time to explore the future of humanity.
And on top of this, the Digital Collector’s Book, a Signed Wallpaper, a Unique Forum Avatar and Icon!
