Quillscript Plugin, formerly known as Snowfall, is an Unreal Engine code plugin. It controls the story and narrative flow for RPGs, visual novels, and other story-driven games. Including player choices, story branching, conditions, code integration, and much more. All of that is done through an easy-to-use screenplay-style scripting language.
