Rocket League’s newest update, which overhauls the game’s XP and progression systems, will roll out to all platforms on Aug. 29, Psyonix announced today.

The Progression Update will be followed, by one week, by the introduction of the “Rocket Pass.” Psyonix said. Both the new XP system and the $9.99 Rocket Pass were announced back in June.
