The Sea of Thieves Xbox Controller is a limited-edition Xbox controller available for purchase separate from the the Sea of Thieves game.
Players who purchase the controller are given access to the exclusive Ferryman Clothing Set.
The controller features a tactile splatter pattern intended to be reminiscent of "barnacles" having covered the controller from its time spent on the sea. This was achieved via "a bespoke laser-etching solution."
There is also a glow-in-the-dark "Reaper’s Mark" and a translucent case with a gradient color fade.
