Galactic Civilizations IV Supernova

Galactic Civilizations IV: Supernova is a 4X turn-based strategy game set in the 24th century where you take on the role of leading a spacefaring civilization that has just developed faster-than-light (FTL) travel.

You begin the game with only your home planet and must research new technologies, explore the known galaxy, and colonize new worlds while keeping your people at home happy. At the same time, you will engage in trade, diplomacy, intrigue and war with other alien civilizations. Thanks to the invention of hyperdrive, your people are now ready to discover new worlds, encounter alien civilizations, and learn about the dark history that encompasses them all.

Galactic Civilizations IV: Supernova gives you an entire galaxy to explore and customize. Using cutting-edge AI technology, you will be able to create entire civilizations that both look and feel unique just by entering a few lines of text. The AI will generate custom lore, diplomatic dialogues, starship choices, and ambassador images, leaving you with a one-of-a-kind civilization to play as or against.

Each civilization has a unique story to tell and is powered by a sophisticated and nuanced AI entity with its own ambitions and goals. Our unrivaled ship designer lets you stay ahead in an endless arms race by designing custom starships to counter your adversaries’ strengths.
