Earlier this year the developers of Rocket League, Psyonix, announced they would bring cross-platform capabilities for the Xbox One and PC. They have now released a patch to add this feature to these platforms. The developers listened to the community when they asked for this feature as originally PS4 and PC players already had this capability since game launch last year but was absent from the Xbox One release in February.
This is the first ever Xbox One game to support cross-network play with a Steam PC game. This feat was achievable due to Microsoft’s new cross-platform policies. This feature can be toggled in the options menu if you don’t wish to play cross-network. Hopefully this will open the door to many more cross-platform games in the future.
