Psyonix have announced that their Friends List update for Rocket League will be arriving on February 19th.
The update will gibe players cross platform party support. Gamers will be assigned a Rocket ID which will be used to add players on other platforms to your friends list and then you will be able to invite them into a cross platform party and play the game together. You will always be able to customise your Rocket ID.
The new Friends List will be added to the main menu and will show all your friends playing on your current platform, Rocket ID Friends, recent players and an alerts tab.
Clubs will also become cross platform enabled.
