Sea of Thieves is a shared-world pirate adventure game developed by Rare and published by Xbox Game Studios. Players sail the seas alone or with a crew, hunting for treasure, completing voyages, battling skeletons and sea monsters, and engaging in ship-to-ship combat with other players.
The game features an open ocean environment where crews navigate sloops, brigs, or galleons, manage sails and cannons, and bail water during battles. Progression comes through reputation factions like the Gold Hoarders, Order of Souls, and Merchant Alliance, as well as the Pirate Legend title earned by mastering all trading companies.
Sea of Thieves is notable for its emergent PvPvE gameplay, where every session blends cooperative sailing with unpredictable player encounters. Major expansions have added story-driven content, crossover events, and the Safer Seas solo mode introduced in 2024.
