Mount & Blade II: Bannerlord - War Sails
Sail the high seas, lead mighty fleets, and forge your legacy in War Sails, the epic single-player expansion for Mount & Blade II: Bannerlord. Bringing naval warfare to Bannerlord for the first time, War Sails lets players command powerful ships, engage in thrilling sea battles, and master maritime conquest.
Embark on daring naval adventures with new mechanics, territories, and challenges. Customize your fleet, conquer settlements, and carve your legend on the high seas!
MEET THE NORDS, A NEW VIKING-INSPIRED FACTION
Chart your course to the Northern Kingdom, home of the fearless Nords—legendary seafarers and masters of close-quarters combat. Explore a land of jagged peaks, vast taigas and freezing fjords, where scattered settlements rise like ships from the sea. A bold adventurer may trade their goods, recruit their warriors, join their ranks or challenge their rule. Will you join the North or seize its riches?
MASTER NAVAL WARFARE
War Sails introduces a unique and immersive naval warfare system that has been inspired by accounts of actual medieval sea battles. Featuring realistic wind and water physics, ship-to-ship combat lets you board enemies from multiple points, ram them, or attack from afar.
Captains can seize opportunities by boarding already engaged ships, prepare for an incoming attack by creating a floating fortress or take a risk to tie down several enemies at once - giving their allies an edge elsewhere. They may ram an enemy ship to sink it - or at least throw men off board, shatter oars and compromise buoyancy. Well-placed arrows and ballista fire can also tear through sails, further crippling mobility.
EXPLORE AN EXPANDED WORLD
Calradia has been reimagined with a northern region, a settled island, coastal waters and open seas. The dynamic weather system was also refined to include storms and trade winds. Ships move faster when riding the gales, but beware—attrition can unravel even the best-laid plans.
The naval systems and Nord faction integrate into Bannerlord’s world, reshaping trade, warfare, and diplomacy. Ship production and new trade goods add regional variety. Coastal towns may grow rich from this — if they can fend off pirates and naval invasions.
Sieges have also been adapted to naval warfare. Armies will have to bring along a fleet and set up a blockade, if they want to stop supplies and reinforcements arriving over sea.
BUILD YOUR FLEET
Command 20 unique ships, from nimble trade vessels to towering war galley. Includes 15 warships, 4 trade ships, and a civilian fishing ship - each modelled after historical vessels, with distinct handling shaped by realistic wind and wave physics. They can be customized with siege engines, cargo holds, sails, rams, and more. Shipyards build and stock vessels based on their town’s culture and development. Players can also capture ships and figureheads in battle.
EXPAND YOUR ARSENAL
The character system has been extended with Nord hairstyles, beards, and tattoos. Three nautical skills were added that enhance navigation, tactics, and stewardship. There are also many new items including spears, swords, axes, shields, and armor.
Troop trees now include mariner troops that are more effective at sea. Players can also recruit new companions with maritime backgrounds.
LEARN THE ROPES
A new questline introduces players to the seas of Calradia through cinematics, scripted missions, and classic Mount & Blade gameplay. Learn how to command your ship, then take it into battle against a pirate confederacy. Lead a growing fleet of newfound allies as you face a range of nautical challenges.
CUSTOM NAVAL BATTLES
Command fleets your way. Set up and customize your own engagements - choose your hero, faction, and fleet composition, from ship types and randomized upgrades to crew type balance and composition - then set wind, season, and time of day across River, Coastal, or Open Sea maps. No campaign needed.
ENHANCED AUDIO
The sounds of the sea come to life with new Mediterranean and Nordic-inspired musical tracks. Experience rich soundscapes with piercing winds, crashing waves and creaking ships. Feel the heat of battle as steel clashes and sailors cry out.

About Mount & Blade II: Bannerlord
Developed and published by TaleWorlds Entertainment and fully released on October 25, 2022 following a lengthy Early Access period, Mount & Blade II: Bannerlord is the long-awaited sequel to the acclaimed Mount & Blade: Warband. Set 200 years before the events of Warband on the fictional continent of Calradia, the game places players in the middle of a collapsing empire and asks them to decide what comes next — whether through conquest, diplomacy, trade, crime, or any combination of the above.
The game's defining strength is the freedom it gives players to pursue their goals entirely on their own terms. Every playthrough begins with character creation and a choice of background that determines starting skills and equipment, but from that point the world opens up completely. Players can rise through the ranks of an existing faction, forge their own independent kingdom, build criminal networks in cities, lead cavalry charges at the head of massive armies, or simply trade goods between markets exploiting the game's simulated supply and demand economy. Battle mechanics allow players to personally participate in conflicts alongside their troops, commanding formations and fighting in first or third person across sprawling battlefields.
Sieges have been significantly expanded, with players able to construct siege equipment, bombard walls, and coordinate attacks on specific defensive positions. The marriage and dynasty system allows players to continue their legacy through heirs if their character dies. The War Sails expansion, released in November 2025, adds naval combat and the Nord faction for the first time in the series. Mount & Blade II: Bannerlord holds a Very Positive rating on Steam with 87% positive reviews across more than 290,000 players.
Mount & Blade II: Bannerlord is currently available on Xbox Game Pass for Xbox consoles and PC. If you are already a subscriber, you can access the base game through your membership at no additional cost. Note that the War Sails expansion is a separate paid purchase and is not included with Game Pass. If you do not have Game Pass, GameBoost offers Xbox Game Pass gift cards as an alternative way to get started.

Very nice game. Logical development of ideas with Warband. I didn't see any major revolution, but it wasn't particularly needed either. It's just that title was already old and it was necessary to refresh it. Especially the appearance of the NPC was able to scare away. Is not for those who like only the film plot games. It requires more imagination, because we create our own story. It's a total sandbox, a bit like Minecraft (I mean, I think I've never played, but I bet they have some similar.
