New Arc Line is a story-driven role-playing game set in a steampunk fantasy world where magic and industrial technology collide, and tensions run high between humans and other races. Players create a character and make their way through a city shaped by that conflict.

Choices in dialogue and quests shape how the story unfolds, while companions join the party for tactical combat encounters. It's aimed at players who enjoy classic-style RPGs with a distinctive setting and consequential decisions.
