How do I change the language the game runs in?

If you wish to play the game in any language other than English, you must first install the correct data packs. To do so, please follow the Installation & Activation instructions in the ReadMe provided with the game.

Once you have done this, the other language(s) will be available to you.

By default, the game will run in the same language as your OS. However, if you wish to play in a different language, you can change it using the Deus Ex: Human Revolution - Ultimate Edition pre-game Options window.

To do this, follow the steps below:

1. Double-click on the Deus Ex: Human Revolution - Ultimate Edition application icon while holding the Command (⌘) key down. The Deus Ex: Human Revolution - Ultimate Edition pre-game Options window will appear.

2. Select the Advanced tab.

3. Select your preferred language from the Language drop-down menu. The available languages are Deutsch, English, Español, Français, Italiano, Polski and Русский.

4. Click the Play button. A dialog box will appear to inform you that the application has to be relaunched. Click the Relaunch button.

5. When the Deus Ex: Human Revolution - Ultimate Edition pre-game Options window appears again, click the Play button to launch the game.
