The final beta version of Sea of Thieves—an upcoming Xbox Play Anywhere title—is free to play for the next three days. So if you’re curious whether Microsoft’s new shared-world experience is for you, now is the time to find out.

“As we head towards launch on March 20, we have one Final Beta test to run,” Rare’s Joe Neate explains. “This gives us an opportunity to grow our scale testing to our largest number yet, it allows us to test a broader range of features than ever before and it also gives anyone that is interested a chance to play and experience Sea of Thieves first-hand.”

Sea of Thieves has been in development for over a year, and Microsoft and Rare have really opened it up to a wide group for testing to ensure that it works properly. Better still, it’s exclusive to Microsoft’s platform and is cross-compatible across Windows 10 and Xbox One, and takes advantage of core platform features like 4K video and HDR.

To get started, download the Sea of Thieves Final Beta from the Microsoft Store on Xbox One or Windows 10. It requires an Xbox Live account on Windows 10 or an Xbox Live Gold account on Xbox One.
