Set sail in Old of Sea — a real-time naval strategy MMO where every cannon shot matters.

Customize your warship, upgrade weapons, join a guild, and battle for control of the open seas. Hunt down pirates, capture rivals for ransom, or rise through the leaderboards as the most feared captain on the map.

REAL-TIME NAVAL COMBAT
Auto-targeting cannons, critical hits, range and accuracy mechanics, gunpowder and shield buffs. Every battle plays out live against real players — no bots, no fake opponents.

ISLAND CONQUEST & TOWER DEFENSE
Guilds invade rival islands defended by 12 upgradeable towers. Coordinate raids, defend your stronghold, and claim territory across the map.

SHIP CUSTOMIZATION
Upgrade your launchers (damage, range, reload, crit), pick your ammo loadout, swap skins. Build the warship that fits your playstyle.

GUILD WARS
Form alliances of up to 50 captains. Share resources, capture Guild Islands, and climb the rankings together. Coordinate strategy through guild chat and announcements.

PIRATE ECONOMY
Drop an enemy below 30% health and force a ransom payment. Loot gold from defeated rivals, trade in the open marketplace, and outsmart competitors in live auctions.

LIVE LEADERBOARDS & CHAT
Global chat and direct messaging, real-time rankings, server-authoritative gameplay. Compete fairly against real players from around the world.
