Bannerlord Coop Campaign v0.2.1 Released!

Bannerlord Coop Campaign allows players to experience a Mount & Blade II: Bannerlord campaign together with friends or stream communities.

The host runs the campaign on their computer and creates a dedicated multiplayer server. Both the host and other players join this server through Bannerlord's multiplayer mode.

While traveling on the campaign map, the host streams or shares their screen with the other players. Whenever a campaign battle begins, it is recreated on the multiplayer server, where the host and connected players can fight together. Once the battle ends, its results are transferred back into the campaign.

Players only need to join the server once and wait for the host to start a battle.
