Teaming up against the AI
Multiplayer supports up to 8 commanders, and you can forge alliances against an AI opponent instead of fighting each other. The flexible map generator gives you fresh ground for each rematch, so co-op friends can keep the same routine: build fast, share a front, and see whose flank holds.
Eight commanders in one battle
If you prefer facing off, lobbies take up to 8 players for competitive victories. Everyone starts with resource production and town building, researches technologies, and races toward larger armies. With 20 nations, 120 unit types and 100 research options to pick from, matches turn on choices about when to expand, when to upgrade, and when to attack.
An economy that feeds the army
Battles this large need a working town behind them. You send peasants down the mines, chop forests for wood, and keep crops growing to feed everyone. Town prosperity matters as much as field victories, so you watch food, gold, wood and stone while your troops move. It is the old RTS loop at full size: more peasants, more resources, more soldiers, and then the satisfying problem of having too many mouths to feed.
Land battles and sea battles
Besides fights on land, you can build an armada and take the war to sea. Battles can hold up to 32,000 units at once, with massed infantry formations, cavalry and artillery deciding things on shore. Landscape shapes tactics, so hills, forests and water are worth reading before you commit. With over 220 historic buildings across the nations, your base looks the part of the period while the army does the noisy work.
Good to know before you play?
How does co-op work in Cossacks 3?
Up to 8 commanders can play together, either competing for victory or forging alliances against an AI opponent. For co-op friends, that means shared wars: build your own towns and armies, coordinate attacks, and take on the AI side by side on generated maps.
What do you actually do in a match?
You gather resources with peasants, construct buildings, research technologies, raise an army and fight on land and sea. Mines, forests and crops keep the economy running while you lead infantry, cavalry, artillery and ships, with terrain shaping how battles play out.
Is there anything for solo play too?
Yes. The standard edition includes five singleplayer campaigns based on 17th and 18th century events, from Turin and Khotyn to Edgehill, Mogilev and la Manche.
