How to enable subtitles on Bioshock Remastered since, for some reason, you cannot enable it through the menu.
Open the Bioshock configuration file
Navigate to the configuration folder:
<C:\Users\YOUR_USER_NAME\AppData\Roaming\BioshockHD\Bioshock\>
Open the file with Notepad:
<Bioshock.ini>
One easy way to open the file is to press <Windows Key + R> and then paste:
%appdata%\BioshockHD\Bioshock\Bioshock.ini
Edit the Bioshock configuration file
Search for this line (you can use <CTRL + F> to do so):
DialogSubtitles=False
Replace it with:
DialogSubtitles=True
Save the file and close Notepad.
