If you’ve been waiting for a reason to reinstall Mount & Blade II: Bannerlord, War Sails is it—the expansion is out today (Nov 26, 2025) and it finally brings full naval warfare into Calradia.
What is “War Sails” (and why it’s a big deal)
War Sails is a major single-player expansion that adds the one thing Bannerlord fans have memed about forever: ships you actually command—not just scenery. Expect fleet battles, boarding actions, and the kind of chaos Bannerlord does best, now with waves and wind involved.
The headline features
Here’s what you’re getting with War Sails:
Naval combat with physics: wind + water affect handling; fight by ramming, boarding from multiple points, or ranged attacks that can cripple sails/oars.
A new Viking-inspired faction: the Nords plus a northern homeland built for raids, trade, and close-quarters violence.
An expanded map & sea gameplay loops: northern seas, islands, coastal waters, storms/trade winds, and sea-based strategy like blockades impacting sieges.
Build a fleet (18 ship types) with upgrades like rams, cargo holds, sails, siege engines, and more—plus capturing ships/figureheads in battle.
New questline & new gear: nautical-focused progression, Nord flavor additions (cosmetics), and new items/skills designed around maritime play.
In short: War Sails doesn’t just “add boats”—it rewires the strategic layer so coasts and rivers become real front lines.
Do you need the base game?
Yes. War Sails requires the base game Mount & Blade II: Bannerlord to play.
