Project Seaborne is an open-world sailing game set across an entire world of open ocean and coastline. Players captain their own ships: they trade cargo between ports, design and refit vessels at the shipyard, and command a fleet of consorts. Naval combat is fought broadside to broadside against pirates, rival nations and crown warships. Wind, weather, storms and the day-night cycle shape every voyage, and captains must keep their crew fed, paid and loyal to stay at sea. Players can sail solo or join friends in online co-op.
