Stellaris: Utopia is an expansion for the grand strategy game Stellaris that introduces new ways to develop advanced empires, including megastructures and specialized governance paths. It builds on the base game's systems of exploration, diplomacy, and expansion.

Players can pursue ambitious late-game projects and refine how their civilization evolves politically and technologically. It appeals to existing Stellaris players wanting deeper strategic options for shaping their galactic empire's identity.
