About the Mod

Bannerlord Coop transforms Mount & Blade II: Bannerlord’s single-player campaign into a cooperative multiplayer experience.

Players share the same persistent campaign world while controlling their own characters, parties, clans, troops, and resources. Travel across the campaign map together, interact with settlements and NPC parties, or fight alongside—and against—other players.

Play campaigns with up to as many players as the server can handle. We've had servers with over 32 players!

Multiplayer Battles

Players can participate in field battles and sieges as allies or opponents. AI parties may also join active battles under supported campaign conditions.

Players who retreat or disconnect are handled by the campaign and battle synchronization systems, allowing the shared game to continue without ending the entire session.

Hosting

For the best performance and stability, we strongly recommend hosting campaigns through the included dedicated server. The hosting instructions can be found in our Discord through this link.

Steam hosting does not require traditional port forwarding in most cases. Manual network hosting options are also available.

Detailed installation and server setup instructions can be found in our documentation and community server.

Compatibility

For the most reliable experience:

• Use the supported Bannerlord game version

• Disable all other mods

• Do not enable the War Sails DLC

• Ensure every player is using the same mod version

Compatibility with other mods is not guaranteed.

Before submitting a bug report, please include:

• What happened
