While there is no dedicated "offline LAN" button, the developers designed the game with a single global server where you can create private rooms to play with friends on the same local network.
Avoid maps with dense forests or complex coastlines. The AI pathfinding for ships and infantry through forests destroys CPU cycles. Use "Ukraine" or "Steppe" – wide, open terrain.
Since there is no official button, you must use a community-hosted server tool to redirect the game's traffic to your local network.

Cossacks 3 is a resource-heavy game. When you have 8 players each commanding 5,000 units, the data transfer requirements are immense. Playing over the internet introduces latency, "lag spikes," and the dreaded desynchronization errors. A environment minimizes latency to near-zero. The speed of the local network ensures that when you order a formation of musketeers to fire, they fire instantly. For competitive play, this responsiveness is not a luxury; it is a necessity.
