Sea of Thieves
Rare’s shared-world pirate game. Eight years in, deeper than ever.
Welcome to the Cosmo strategy hub for Sea of Thieves. Rare’s shared-world pirate sandbox launched in March 2018 and celebrated its eighth anniversary in 2026. Currently in Season 19 (Act 3 in May 2026), the game has evolved into a layered system of Trading Companies, Factions, voyages, Tall Tales, World Events, and the Hourglass of Fate PvP queue. Cross-play across PC, Xbox, and PlayStation 5; cooperative or competitive depending on your mood and ship. Everything below is vanilla, mechanics-only knowledge — the shared-world loop, ship types, Trading Companies and Factions, voyages and Tall Tales, PvP through the Hourglass of Fate, World Events, ship combat, treasure economy, personal combat, audio and settings, and pro tips.
