Upgrades

Upgrades are an essential part of Cossacks 3, offering substantial advantages over your foes. Due to the way the gameplay is structured, nations have different technology trees and not all upgrades are available to every nation. The most characteristic example is navy: Only Turkey and Algeria get to build xebecs. Upgrades have been divided by building and category.
