Microsoft enables Cross-Network play, Rocket League confirmed first to support
In what is certainly a welcome development, Microsoft has announced that they will be allowing developers to enable cross-network play for their games. This means that Xbox One and Windows 10 users currently playing via Xbox Live will have the ability to play with players from other networks (like Steam and the PlayStation Network). Given this development, Psyonix has announced that Rocket League, their wildly-successful vehicular soccer game, will be one of the first games to have cross-network play between PlayStation 4, Xbox One and Steam players.
Rocket League has been a massive hit since it’s debut on both PS4 and Steam, even generating enough buzz as an e-sports game. Xbox One users has just been given a taste of the action a few months back, and as such requests for cross-network play with Steam and PS4 users have become rampant. Today, Psyonix (through their blog) have confirmed that Microsoft has allowed them to push through with cross-network play, the only game so far to do so. Xbox One and Steam cross-network play will be up in Spring 2016, while PS4 users will have to wait awhile to play against the Xbox One players.
It is unclear as to which other developers would follow suit as of this writing.
