Rare has announced Sea of Thieves, a new IP for the studio, at Microsoft's Xbox conference.
The pirate-themed multiplayer game, described as Rare's most ambitious title to date, allows players to group together to explore islands, seek out treasure and fight enemies. The reveal trailer showed a colourful and cartoonish tropical world, with dense jungle and a harbour area.
Player names appear over their avatars, suggesting an MMO-like experience.
Once assembled together in a group, players will be able to take to the ocean in their own vessels, explore the world and do battle with other groups of players in their very own ships. Expect cannonfire and ship-ramming in these high-seas encounters.
