Official Introduction Key Points

1. Chart Your Own Course
2. World of Sea Battle is a massive open-world MMO set in the Age of Sail, where every captain shares the same sea but charts their own course. Hunt pirates, cross swords with other players, explore distant shores, haul cargo and grow your fleet. The economy is in the players’ hands, and guilds wage war for territory.
3. Build Your Fleet
4. Weigh anchor in a humble schooner and rise to command a 100-gun first-rate ship of the line. Over 50 historical sailing ships from the 16th to 19th centuries await: schooners, galleons, brigantines and frigates. Upgrade your ships, refit their gear, change their look and build a fleet that suits the way you sail.
5. A living open world
6. Set sail into the unknown. The whole Archipelago is one seamless sea, from the warm southern islands to the icy north. Merchants, pirates and other captains sail it alongside you, and any sail on the horizon could be prey or a threat. Past the edge of the map lies the Endless Sea, uncharted and full of danger.
7. Command the Battle
8. Watch the wind, change course and pick your moment for a broadside. Round shot smashes hulls, bar shot tears sails and grapeshot cuts down crews. Enemy too heavily armored? Set it ablaze with heated shot. The right shot at the right moment can decide the battle. And if cannons aren’t enough, close in on your enemy and board their ship.
