From the campaign:
For over two years our team has been brainstorming, designing, play-testing, and analyzing every detail to make Advent Saga a game we can be proud of. While making sure to keep many positive aspects of card games that we love; we wanted to bring a completely new competitive gaming experience to the public. We decided to have a Kickstarter Campaign to further expand our community. We hope that the support garnered from this will help us transition out of Alpha and into Beta. Below you will find more information about Advent Saga. Our team's journey with this project has been an exciting one, and we truly hope that you enjoy what we've created.
We will be adding a number of updates in the coming weeks, including videos and explanations of Advent Saga’s current and upcoming content. With each of these updates, we will be revealing special rewards to allow you to see what we’re offering firsthand. Please feel free to message us with questions; we'll be more than happy to answer any that you may have.
Advent Saga is a story-driven physical and digital Tactical Card Game that combines the excitement and traditions of popular card games, with the strategic elements of Tactical RPG's.
