A free mod for Mount & Blade II: Bannerlord, by Benjamin R – a solo guy.

This is an overhaul of the vanilla game’s troop trees. It makes them much more flexible and balanced. I’ve divided them into different specialties, which gives each tree more diversity and strategy. It also removes the endless options of the vanilla game, and keeps them in a more realistic and strategic scope.

This means that your units can specialize in melee, ranged, or archery attacks, and can use shields or heavy weapons. There is also elite infantry that can use swords and mace, as well as light and heavy swords. There are even heavy war elephants!
