Back at this level and you'll get both Heart of Glass as a Foundry adventure module and the PDF at a discount (normally $13). 

The Foundry module will include the entire adventure in journal form and all the characters as actors. The audio files and handouts will also be included along with any pertinent maps or blueprints. It will be fulfilled as a zip file version (it's easy to install!) via Drive Thru RPG and will receive updates on that platform.
