How to change the language in Rocket League

Rocket League ^[1] has players come together worldwide to play with and against each other. Thanks to this, having the language you’re comfortable with the most play every time you play the game can increase immersion and let you feel more at home. However, changing the Rocket League language is easier said than done.

Fortunately, there are two reliable ways players can change the language in Rocket League. The first is through the Epic Games Launcher, while the second is through Steam. The method you use depends on which launcher you use to play the game.

So, without further ado, here’s how you can change the language in Rocket League.

Changing the Rocket League language on Epic Games Launcher

The language for players accessing Rocket League through the Epic Games Launcher involves using a specific command-line argument. This tells the game which language to use when it starts, so it loads in the one you want. 

Before making any changes, make sure Rocket League is fully closed. The game checks its language settings when it starts up, so any changes made while running won’t take effect while you restart it. To change the language in Rocket League using the Epic Games launcher:

1. Begin by launching the Epic Games Launcher application on your PC
2. Click the Profile icon in the top-right corner of the launcher window. It usually shows the first letter of your name. Then, choose ‘Settings’ from the dropdown menu.
3. In the settings menu, scroll down until you see ‘ROCKET LEAGUE’. Click on it to expand the options just for the game.
4. Check the box next to ‘Additional Command Line Arguments’. You can type in the language command in the text field that pops up.

In the text field that appears, enter the command exactly like this: -language=xxx. Replace xxx with the 3-letter code for the language you want. For example, use -language=INT to set it to English. So the game can read it correctly, ensure you type it exactly as shown, including the dash and equal sign. After you enter the command, Rocket League will launch in the new language the next time you open it through the Epic Games Launcher. This shows that the language setting takes effect when the game starts.

How to change Rocket League language on Steam

For players using the Steam client to play Rocket League, you’ll see that changing the language is quite simple. It’s very easy to adjust since the setting is conveniently located directly in the game’s properties.

Before you start changing things on Steam, it’s a good idea to double-check that Rocket League is completely closed, just like you would for the Epic Games Launcher. This helps the game properly pick up the new language settings when it starts up again. To switch Rocket League’s language on Steam, follow these steps:

1. Launch the Steam application on the PC
2. At the top of the Steam window,  click on ‘Library’. This will show a list of all the games you own.
3. In the left column where all your installed games are listed, click ‘Rocket League’.
4. Find ‘Rocket League’ in your list and right-click it. When the menu pops up, choose ‘Properties’.
5. In the ‘Properties’ window that appears, click on the ‘Language’ tab. This section lets you manage the game’s language settings.
6. Use the drop-down menu in the Language tab to pick your preferred language.
7. Click “OK” to apply the changes and close the “Properties” window.

One important thing to know when changing the language through Steam is that additional files might need to be downloaded. If your chosen language isn’t ready on your system, Steam will start downloading it. This could cause a short wait before you launch Rocket League in the new language. Letting users know about this helps avoid surprises and frustration if the change doesn’t happen immediately.

Important Rocket League language codes

Whether you launch Rocket League through the Epic Games launcher or Steam, the game uses the same 3-letter codes to identify languages. This means that even though the way you pick the language might be different between launchers, the game understands and applies the language choice the same way. Below is a list of all the supported languages and their 3-letter codes, which are important for users using the Epic Games launcher’s command-line method.

• English - INT

• Italian - ITA
• German - DEU
• Spanish - ESN
