[size=medium]As of today, Rocketleage players can battle each other regardless of what platform they are on. Psyonix has announced (here) full cross-platform play for PS4, Xbox One, Nintendo Switch, and PC (Steam) players. Like Fortnite, Rocketleage is the second title to enter the PlayStation Cross-Play Beta program. Now players can randomly join matches between any platform!
However, if you wish to only play with PS4 players you can disable it in your settings. It is enabled by default. To change this setting navigate to the "Main Menu", then "Options", Then you should see "Cross-Platform Play" in the "Gameplay" Tab.[/size]
