Talk of cross-platform multiplayer continues to grow, following a surge in support throughout 2018. While Microsoft and Nintendo were among those at the forefront of efforts, we've recently seen Sony change stance, gaining heightened traction across PC, console, and mobile. It's still far from the norm but becoming increasingly attractive amid pressure to drop long-established barriers.

A recent update to Steam's beta now hints at deeper cross-platform integration, with source code directly committing to Xbox-related networking features. As posted to ResetEra, new additions to the Steam Beta GitHub repository seemingly refer to Xbox Live identifiers.
