If you're all about the PC and your friend is all about the Xbox One but you both enjoy playing Rocket League, then rejoice! Cross-platform play is now available for the two versions. So, if you want to team up with a buddy on the Xbox to dunk some hoops, or you've got a "PC Master Race" friend that's been waiting to team-up and play a little car footie, the only thing holding you back now is (likely) your Internet connection.
Since its release last summer, Rocket League has blown up in a way that no one really saw coming. As of this past February, the title has reached a player-base of 12 million and grown in its eSports "phenom" status. It's even grown to a point where Microsoft has tossed out the idea of doing cross-platform with the PlayStation 4.
For now, though, the PlayStation 4 and PC can play together, and the Xbox One and PC can as well. If you don't want to do any cross-platform, however, you can disable the feature in the game's Options menu.
