Anno 1800 Lan Multiplayer Link -

"Anno 1800 is a city-building and management simulation game developed by Ubisoft. Released in 2019, it allows players to build and manage their own industrial revolution-era cities. The game features both single-player and multiplayer modes. In multiplayer, players can interact with each other, trade resources, and even form alliances or engage in competitive gameplay.

Beta Branches: Ensure neither player has opted into a "Beta" or "Public Test" version of the game on Steam or Ubisoft Connect, as this will create a version mismatch with the standard game.

Mod Conflicts: If you are playing with mods (via the Anno 1800 Mod Loader), all players in the LAN party must have the exact same mods installed and activated. Otherwise, the game will desynchronize immediately upon joining.

However, you can still play with people on your local network. The game will automatically prioritize the fastest connection available between players once the session is established through the Ubisoft lobby. How to Start a Multiplayer Session anno 1800 lan multiplayer link
