This page is our investigation of cross-play game Sea of Thieves. We always verify information manually using official sources - no AI.
Sea of Thieves supports full cross-play between all available platforms. Players on PlayStation 5, Xbox Series X|S, and PC (via Steam and Battle.net) can play together.
We found information about cross-play in Sea of Thieves on the official website, which you can check by yourself. [source]

We also want to mention that, in the screenshot and source above, PlayStation 5 and the Battle.net store are not listed as available for cross-play. This is because Sea of Thieves for PlayStation 5 and Battle.net were released long after the Steam version, but they also have cross-play support.
Here you can see the announcement of the release on PlayStation 5, with proof of cross-play support. [source]

A year after the release on PlayStation, Sea of Thieves was released in the Battle.net store with cross-play support. You can check the official announcement here.
