Spartan Games have posted an article on their website showing and discussing the four “Specials” models they will be releasing for each Dystopian Wars faction.
From their website:
Moving on to the specials, they are intended to become striking additions to your fleets and inject an extra few litres of steampunk into the proceedings. Although most factions will eventually have access to robots or submarines at some point, the specials give a few extra tweaks to your tactics. You are also able to field quite of few of them in your fleet if you wish.
