Ports, contracts, and player-driven prices

Ships, guns, and goods reach the market through other players. When wars flare, demand shifts—smart traders profit, greedy raiders risk the noose. Build influence from a humble brig to a line-of-battle monster.

Galleon and sea-stack settlement in the Archipelago

PvP, PvE, economy, exploration

Fly a merchant pennant and sail in relative peace—or raise the black flag and hunt cargo. Guilds clash for ports; solo captains probe the edges of the map.

World of Sea Battle: ships exchanging broadsides on the open ocean

PvP & PvE

Peaceful trader or privateer

Shipyard UI: fleet grid, stats, and construction options in World of Sea Battle

Economy & trade

Prices follow the fleet

Cannons, hulls, and commodities are supplied by players. Shortages and wars move the market—plan runs like a real factor house.

Shipwreck and shallows—exploration in dangerous waters

Open world

Isles, fog banks, secrets

Roam a large sandbox, push beyond the charted routes, and—if fortune allows—claim space to call your own.

Ships of the line—and lighter hunters

From nimble sloops and frigates to 100-gun first rates, World of Sea Battle spans the golden age of fighting sail—and dozens more vessels lie beyond this short list.
