S&M NW for BCoF when?
The guns are kinda of there you got some 1816 muskets which should act as Napoleonic Wars guns. If you wanted to do UK and France you would just have to make the models. But mods are still mostly client side only but when you can server enforce mods that will be cool.a
Now imagine if a certain modproject for Bannerlord already had lots of weapons, uniforms, and other props ready to go

(I'm speaking as a private person here, not in function. I do not know of and cannot possibly comment on any plans regarding BCoF. Sword&Musket is being developed for Bannerlord at the moment.)
