PARTY TIME!
Along with a Tournaments Beta before the year is done, we will also be testing a new Party System that we're building directly into Rocket League. When finished, this new system will allow you to party up directly via PsyNet instead of the party systems currently used through Steam, Xbox Live, or the PlayStation Network. Our first test(s), however, will be limited to Steam players.
Once your account is flagged for the new Party system, your game will automatically sync with your Steam Friends List information and allow you to create a party via PsyNet. You'll still use the 'Create Party' button as you normally would, but instead of seeing a Party invite in Steam, you'll see new in-game notifications alerting you to a Party invite.
While the PsyNet Party System is Steam-only, this is the first step in enabling the possibility of supporting cross-platform parties at a later date. We'll have more information about the new Party System once we're closer to launch.
