The Llama-Rama crossover will can help you liberate themed rewards in Rocket League and Fortnite by completing five Rocket League challenges. Here's everything you can liberate, and what you will want to RL Items  do to get your hands on the loot:

Rocket League task: Get MVP in any on line match with the llama wheels

Rocket League praise: Battle bus + struggle balloon antenna, conflict bus wheels, and war bus engine audio
Fortnite praise: Octane RL backbling + fashion version

Musician DJ Slushii, who I'm informed is a "Rocket League fan-preferred", will also be putting on an in-recreation Fortnite live performance to close out the Fortnite Presents: Spotlight collection. If you, like me, are 1,000 years vintage, you might not recognise who that is, but in case you play Rocket League your ears will at least be acquainted with considered one of his tracks, LUV U NEED U, which features on the in-recreation soundtrack. 

DJ Slushii's performance starts on Rocket League Items Shop September 26 at 10 pm BST/five pm EDT/2 pm PDT, beginning the Llama-Rama crossover.
