How can I access the Mea Culpa DLC in Blasphemous II?

The Mea Culpa DLC is accessible directly within Blasphemous II. This means that you'll need to launch the game to access it.

You may see two separate icons in your library: 

• Blasphemous II
• Mea Culpa OST

This is intentional; the OST can be launched separately via its separate icon, while the Mea Culpa DLC is accessible only through the game itself.
