Today, the Rocket League progression update is out in the wild, having rolled out to all platforms. There’s a lot to take in with this update, especially since it changes the game’s entire leveling system ahead of next week’s launch of the Rocket Pass. Clubs are also in the game now, which lets a band of up to 20 players connect together as a group. Also added are some new trophies, and a big list of other tweaks and updates.
