Galactic Civilizations Wiki

With over 150 technologies in five categories, GalCiv II will keep you really busy if you want to research them all.

Technology is researched during the game, unlocking planetary improvements, ships and bonuses. Twilight of the Arnor Technology is quite different depending on your starting race or custom technology tree. In Dark Avatar and Dread Lords, Technology is divided into different categories: diplomatic, propulsion, engineering, weapon, and defense.
