Cossacks Game Series
"Cossacks" is a series of strategy games from the Ukrainian company GSC Game World, which tells about the global confrontation of the 17th-18th centuries among all the European powers of that time, including Russia, Ukraine, Poland, and other well-known countries.
The first "Cossacks" represent a huge collection of historical campaigns with the ability to play for completely different sides with "evolution" across several eras and a multiplayer mode for friends, while the second "Cossacks" introduced a mode with a world map and its conquest.
As in other real-time strategies, the main objective is to destroy the enemy's base while not losing your own.
