Sea of Thieves launches for Xbox One and PC on March 20 and will support cross-play between the two platforms. Ahead of the game's release, Microsoft will sell a limited quantity of cool-looking Sea of Thieves Xbox One controllers, which come with a Ferryman Clothing DLC set and 14-day trials for Xbox Live Gold and Xbox Game Pass. Microsoft also announced that Sea of Thieves will be the first Xbox One-exclusive available on Game Pass the day it launches.
