TaleWorlds Entertainment recently released a free add-on for Mount & Blade II: Bannerlord. It doesn't add new content to the game, but gives players the ability to create it themselves.
This is a special set of tools called "War Sails Modding Kit", with which you can create naval content: custom sea maps, you can also build your own ship from scratch and edit existing models. In addition, players will be able to use additional architectural elements to create completely new settlements and scenes of attacking settlements during naval raids.
In addition, the developers released update 1.4.8 for the main game Mount & Blade II: Bannerlord and update 1.2.8 for the War Sails add-on. This is a technical update designed to fix several bugs related to ragdoll physics and more.
The page for the DLC toolset "Mount & Blade II: Bannerlord - War Sails Modding Kit" on Steam is available at the following link. The add-on is available to all War Sails owners for free.
