Galactic Civilizations IV: Supernova

Galactic Civilizations IV: Supernova is a strategy game in which you lead a fledgling interstellar species. Explore the galaxy, research technologies, meet alien civilizations and guide your people as they develop worlds, build starships and fight to survive in a hostile universe.

A living galaxy

An in-game storyteller and a strategic AI populate the galaxy with lore-rich civilizations whose leaders pursue their own agendas. Procedurally generated galaxies, galactic events and rival civilizations create different challenges and opportunities from one game to the next.

Shape your civilization

Use AlienGPT to describe your civilization’s characteristics, preferences and aspirations. The AI uses these to create lore, diplomatic dialogue, starship selections and ambassador portraits. You can pursue a diplomatic and cultural civilization or play as a species bent on spreading to every world.

Develop your worlds

The Core World and Colony system lets you govern a small or large number of worlds. For a “tall” approach, link many Colonies to a handful of Core Worlds to greatly increase their resource output. Or manually improve and develop many lower-class planets for a “wide” approach.

Design fleets and choose strategies

Use the Ship Designer to build and customize spacecraft, choosing from hulls, weapons, engines and other options to suit your strategy. Setup options support games lasting less than an hour or for months, with a range of strategies and playstyles.

Ways to win

You can conquer rivals by force, spread cultural influence, unite rivals under your leadership through diplomacy or earn a Prestige Victory by completing difficult Galactic Challenges.
