Rocket League is going free to play, leaving Steam
Harkening back to the days when Rocket League found its audience as a free PlayStation Plus title, the game is going to be free, permanently. Rocket League is making the move to free to play this summer, following a large content update and a release on the Epic Games Store. The game will be getting a menu revamp, while also improving the way in-game tournaments work, and adding crossplay for the new EGS version. If you've previously bought the game and played online at least once, you'll be "rewarded" with a few perks in the form of in-game items. All DLC will be unlocked for you, you'll get a custom player title that shows the year you first played the game, over 200 items you can equip on your car that will now be considered "legacy" cosmetics, a player banner, and a special boost and wheels. All of those items will be given once Rocket League makes the switch to free to play sometime this summer.
However, the game will be leaving Steam. Those who already own it there will continue to be able to play it there, but new players on PC will have to get it via Epic.
Once Rocket League goes free to play, anyone who already owns Rocket League on any platform (including Steam) will be able to play and enjoy the game with full support for future updates and features. However, the Steam version will no longer be available to download for new players. To put it simply, wherever you play now (including Steam), you'll still be able to play in the future.
