The last two unit cards for the Shadow faction have been completed. The Carcano has already been integrated into the current version of the rules. The next update to the rules will also include the unit card for the Spia.
The Carcano a sniper who uses a composite bow to deliver death from afar. The Carcano is the longest ranged model in the game. She is capable of launching a flurry of arrows to wipe out closely packed targets, and single perfectly aimed arrows to kill at incredible distances. She is very unusual in having 2AP, and being able to directly deal damage.
The Spia, a model capable of hiding amongst your enemies troops, altering opponents tactical commitments and even scoring objectives using your opponents' models. This manipulative spy is a master of winning entirely through covert means.
