Rocket League was made free to play by Epic Games and it has taken the game to unprecedented heights of popularity. Granted, it's a little unfair to players who previously purchased the game, but Epic Games is handing out rewards and DLC packs that are sure to make up for the cost you've made.
How to OPEN Drops in Rocket League and See Item Rewards! (Easy Method)
If you’re one of those players, then you likely have access to every DLC pack that was released for Rocket League before it went free. Here’s a handy guide to help you install all of your DLC packs and get the most out of the content that Epic Games has to offer. Let’s get started.
You will now see a list of all DLC packs associated with your Rocket League purchase via the Epic Games Launcher. If the DLC packs are not installed on your system, the toggles for each pack will be disabled. Simply toggle the switch and EPIC Games should automatically download the appropriate DLC pack for you.
Epic Games will now verify the installed game on your system and re-download and install any missing files. This includes any missing DLC packs that you were unable to use. Once verification is complete, restart the game and your DLC content should now be available in the 'Chapters' section of the game.
