Galactic Civilizations III is the largest strategy sandbox ever made. Start with a single world and expand across the galaxy through diplomacy, trade, cultural hegemony or military conquest in this single-player or multiplayer 4X strategy game. How will you rule your galaxy?
Core Features:
Never the same game twice: Play in the ultimate sandbox where each game has a unique map, unique worlds and new challenges to face.
Multiple paths to victory: Win through military conquest, cultural domination, technological ascension or political alliance.
Story-based campaign: Galactic Civilizations III includes a campaign that brings players up to date on the 20-year story arc behind the rise of humanity in the 23rd century.
Massive technology tree: Research a technology tree with immense breadth and depth. Player choices determine the capabilities of their civilization.
Custom ship design: Players have total control over how their starships function as well as how they look. Any ship you’ve ever imagined can be created or downloaded.
New to Galactic Civilizations III:
Massive scale: The new, 64-bit, multi-core engine increases the number of possible opponents from 16 to 128 with a similar explosion in maximum map sizes.
Ideology: Player actions advance their empires down the path of various ideologies, which unlock unique abilities, planetary improvements, and other bonuses.
Multiplayer: For the first time, Galactic Civilizations is a multiplayer game with full support for custom civilizations, saved multiplayer games and much more.
Unique technology trees: Players can play as any of the eight major galactic powers (or design their own), each with their own unique technology tree, ships, colony improvements and abilities.
Faction Creator: To encourage massive gameplay, the game includes a faction creator that allows players to create a civilization with its own look, ships, technologies and even options for how the AI will use them.
New Battle System: Players assign their ships specific roles to play in combat. You can now view fleet battles in a cinematic style to see your designs in action.
New Colony Manager: The location of a planetary improvement now matters. Adjacency bonuses and planetary resources make a major impact on what a planet is strong (or weak) at accomplishing.
