To play Arc Wars you need the rules PDF, a set of discs and reference cards, a handful of polyhedral dice and 10-15 miniatures from your collection.

The Rules PDF and printable reference cards will be available for free (soon!)

You can order a set of blank acrylic discs from various online retailers. The discs should be about 1.5” diameter and transparent. You’ll need about 30 discs per side.
I purchased an affordable set of 100 1.5” diameter 1/8” thick discs from a shop on etsy that work great.
See the video tutorial below for instructions on how to prepare your discs to play.
