A Genestealer Cult has managed to make its way to Holy Terra. That's what's going on in Shadow Throne, the new box set coming out for 40k this month. To commemorate its release, the exclusive mini from Games Workshop, available in their stores, is a new Genestealer Cultist that you can pick up now.
