This is a bit of a highlight and something I hope we see more of in future. You can now be matched up with people across Steam and all major consoles in Rocket League.
With special thanks to all of our friends and colleagues at PlayStation, we are thrilled to announce that starting RIGHT NOW, Rocket League has entered the PlayStation Cross-Play Beta program! Players on PlayStation 4, Nintendo Switch, Xbox One, and Steam can now randomly matchmake with or against each other in all Online match types (i.e. Casual, Competitive, and Extra Modes).
This makes Rocket League possibly the only game that works online across Steam (Linux, Mac, Windows), Xbox One, Nintendo Switch and PlayStation 4. For us Linux users, it's especially different to actually be included.
In the announcement post, Psyonix noted that cross-platform parties will be coming to Rocket League in the first major update due this year. That's another point that's going to be impressive, to actually have a party of players across all these different systems.
It's such a fantastic game, one I've now managed to put 255 hours into and I honestly don't see myself stopping any time soon. The fact that it's supported officially on Linux too is awesome!
