Cossacks 3 is a real-time strategy video game developed and published by GSC Game World. It is the third installment in the Cossacks series and was released on September 20, 2016, for Windows operating systems.

The game is set in the 17th and 18th centuries and features historical battles and campaigns from that time period. Players can choose from twelve different nations, each with its own unique units and buildings, and compete against other players or the computer in a variety of game modes.

The game’s single-player mode consists of various campaigns that allow players to play as different factions, such as Poland or France, and complete specific objectives. The game’s multiplayer mode allows up to eight players to compete against each other on maps of varying sizes and terrain.

Cossacks 3 uses a resource management system where players must gather food, wood, gold, and stone to build units and structures, research upgrades, and maintain their armies. The game features over 70 different unit types, including infantry, cavalry, artillery, and naval units, each with its own strengths and weaknesses.

Players must also manage their armies strategically, taking into account unit formations, terrain, and weather conditions. The game features a day and night cycle, with weather conditions that affect gameplay, such as rain that makes units slower or snow that makes units more vulnerable to attack.

The game received generally positive reviews from gamers and critics alike, with praise given to its historical accuracy, deep gameplay mechanics, and multiplayer mode. It uses its own proprietary game engine that allows for detailed environments, intricate unit animations, and a large number of units on the battlefield.

As a real-time strategy game, Cossacks 3 contains violence and military themes, so it is not recommended for children. However, it does not contain explicit or graphic content, and the violence is limited to battlefield combat. The game features a variety of historically accurate weapons, armor, and equipment, as well as different types of buildings and landscapes.
