The pirate game has reached some huge success just on Valve's storefront alone.
Rare's classic platformer, which first released in 1998, will be added to the service next month. Additional features have yet to be revealed.
Alien: Isolation's lead designer Gary Napper has now joined Rare as a design director on upcoming action-adventure title Everwild.
Sea of Thieves is giving out a free Halo-themed Spartan ship set to all players who log in before December 1, 8 AM GMT.
Xbox Game Studios head Matt Booty says reports of Everwild's development having been rebooted are "a little more extreme" than what's actually going on with the project.
Rare's multiplayer seafaring pirate adventure continues to move from strength to strength, having amassed over 25 million players since launch.
An Xbox insider claims that a new Killer Instinct game is currently "in active development" at Xbox, though there's no word on who might be working on it.
It's "rare" to see this Rare-developed game being brought up in any discussions today, so what the hell happened to Kameo?
Prepare to head beneath the waves, fight aquatic beasts, and tackle new obstacles and challenges in what's looking like a meaty update.
Players will head "beneath the waves" to "a forgotten world of adventure" in search for a kingdom of lost treasures.
The August update is currently live and adds several improvements to the new Tall Tales along with Pirates of the Caribbean-style cosmetics.
Matt Booty isn't going to tell Psychonauts 2 director Tim Schafer to make a game "that has seasons and goes on for five years."
Following recent reports that the game's development has been completely rebooted, Rare has also confirmed that the project is being led by Gregg Mayles.
Multiple upcoming first party Xbox games are currently scheduled for 2023 launches, according to GamesBeat journalist Jeff Grubb.
Rare's game allegedly rebooted development following the departure of its creative director, and is currently targeting a 2023 launch.
The developers of Hellblade, The Outer Worlds, Psychonauts, and other "dev partners from around the world" will be featured in the extended showcase.
Sea of Thieves: A Pirate's Life looks to be a wondrous journey across high-seas, featuring the incredibly charismatic Jack Sparrow.
Neither will Everwild, Hellblade 2, or Hideo Kojima's new game.
It seems Rare has been working on the game in some form or another for a long time now.
Three of Xbox's biggest exclusives could be even further off than initially believed.
