The stars have called you for millennia and now you walk among them. A universe of possibilities is open to your species as it takes its first fitful steps into the great unknown. Here you can turn your back on the divisive politics of the home planet. Here you can build something new. Here you can unify your people and build that perfect society.

Only in space can you build Utopia.

Utopia is the first major expansion for Stellaris, the critically acclaimed science fiction grand strategy game from Paradox Development Studio. As the title suggests, Utopia gives you new tools to develop your galactic empire and keep your people (or birdfolk or talking mushrooms) happy. Push your species further out into the galaxy with new bonuses for rapid exploration or stay closer to home before striking out against all who would challenge you.

Stellaris is a real-time 4X grand strategy game set in a procedurally generated galaxy. Players control an interstellar civilization, exploring star systems connected by hyperlane networks, colonizing habitable worlds, and managing their empire's economy across resources like energy, minerals, and alloys. The game emphasizes empire customization through species traits, ethics, government types, and civics that shape both aesthetics and mechanics. Gameplay progresses through diplomacy, trade, and warfare with other civilizations, while mid-game and late-game galactic crises introduce escalating threats such as extragalactic invasions or hostile artificial intelligence awakenings. Players can pursue ascension paths including genetic engineering, cybernetic augmentation, or psionic abilities. Originally released for PC, the game later received a console edition and has been supported with numerous expansions adding megastructures, new empire types, espionage mechanics, and additional crisis scenarios.
