The expansion for Mount and Blade 2: Bannerlord, titled War Sails, allows players to engage in naval combat, transforming ground troops into seafaring warriors. Players command their flagship with a crew, deploying up to eight ships and managing formations. An auto-deploy feature is available for easier gameplay. Players must manage sails based on wind direction, indicated by a wind dial, although colorblind accessibility options are lacking. Oarsmen can be called upon when winds are unfavorable, and players can join in rowing. Ships operate as independent units, with players able to issue formation commands or rely on AI captains. Combat includes ramming enemy ships, launching projectiles from ballistae, and engaging in ranged skirmishes. War Sails is set to launch on November 26 at a price of .99.
