Mount & Blade II: Bannerlord - War Sails

Mount & Blade II: Bannerlord - War Sails is a single-player expansion for Mount & Blade II: Bannerlord that introduces naval warfare. The expansion adds a new Viking-inspired faction, the Nords, and a new region featuring coastal waters and open seas with dynamic weather. Players can command and customize a fleet of 20 unique ships, including warships, trade vessels, and a fishing ship, each modeled after historical designs and affected by realistic wind and wave physics. The expansion also includes new nautical skills, mariner troops, and maritime companions.

War Sails integrates naval systems into Bannerlord's existing world, impacting trade, warfare, and diplomacy. New trade goods and ship production add regional variety, while coastal towns can prosper or fall victim to pirates and invasions. Sieges are adapted for naval warfare, requiring blockades to cut off sea-based supplies and reinforcements. The expansion also introduces a new questline to familiarize players with naval gameplay, culminating in battles against a pirate confederacy. Players can create custom naval battles with configurable factions, fleet compositions, and environmental conditions.
