Changelog Chapter 15:
Chapter 15 has nine endings. Two of those are ‘mini-endings’ that come down to a single choice and they resolve the main storyline. The other seven endings are down to a choice as well, but the choices available to you are dependent upon earlier choices in the game (I’ll explain everything in the walkthrough for $10+ patrons). One of those seven is the ‘secret’ ending that will trigger (under very specific conditions) about halfway through Chapter 15. That will be covered in the walkthrough, too.
