In the first of a proposed sequence of monthly content updates, Rare has announced that a brand new event called Black Powder Stashes is now live on Sea of Thieves.
To begin these special voyages you will need to speak with the master of the Bilge Rats himself, Duke, located in the taverns in any of the outposts across the sea of thieves.
Completing the voyages will net you some unique ship customisations as well as new titles to equip for your pirate. Beware though as the voyages involve finding and digging up Stronghold Kegs, more informally known as the MEGA KEG or MEGA BOMB!
