Change the Language in Rocket League
Source-checked About 10 minutes
Answer
Use Rocket League's platform-specific language controls. On Epic Games Store, add the language command; on consoles or Steam, use the platform setting.
Confirm the starting state
Before following the procedure, identify the platform, current game and system language, supported target language, launcher, and any custom command-line argument before changing it. Record the current state so the result can be compared without guessing or erasing useful evidence. Note any affected data, permissions, purchases, security controls, or files that must remain intact.
Identify the platform
Choose the Rocket League language route for Epic Games Store, PlayStation, Xbox, Nintendo Switch, or Steam.
Use the platform's documented control
On Epic Games Store, open Launcher Settings, expand Rocket League, enable Additional Command Line Arguments, and enter the documented language code without spaces.
Restart and confirm the language
Restart Rocket League and check its interface. For console or Steam play, use the platform-specific language steps in Rocket League Support.
Verify the result
After completing the supported steps, confirm that Rocket League restarts with menus and text in the intended supported language while voice or platform text limitations are checked separately. Repeat the original task once so a cached or temporary result is not mistaken for a durable fix, then check that the protected account, data, permissions, and settings still have their intended state.
Troubleshoot Change the Language in Rocket League
If the language is unsupported, a platform setting overrides it, an old launch argument remains, the wrong installation was changed, or only downloaded commentary assets are missing, stop broad resets and return to the last known safe state. Record the exact message, account or device scope, versions, and failed step before using the linked official support route.
