Publisher Xbox Game Studios and developer Rare announced a new Sea of Thieves update bringing a new custom game mode.

The new “Custom Seas” update comes as part of the game’s season 20, and will let players set their own custom game modes later this month, on June 18th.

Here’s a rundown on the new update, plus a trailer:

Rare have lifted the lid on what’s arriving in Season 20 of Sea of Thieves, and it’s an update that will put players in command like never before! In Custom Seas, you’ll have the power to shape the world. Set the rules to create your own custom game modes, add in items and enemies as you see fit, freely assign crews, and capture the resulting mayhem via Free Camera mode to unlock boundless storytelling potential. A number of example creations were also shown, including a Skeleton Scoreboard contest and a Rowboat Royale! Custom Seas launches June 18, free for all players.
