From the website:
We are pleased to announce the release of DLC 02 – The Misadventures of Gelato for Endless: Fantasy Tactics. This is a Pay What You Want release, customers are able to select any price (Including Free!) they wish when checking out. As with DLC 01 (The Trials of Battsu), we will be updating the PDF for Gelato every other week during our regular Visiting Hours post. Once you have added the DLC to your Wargame Vault account you will receive an e-mail whenever the update goes live, and there is no additional cost to download the updated files.
