The latest Privateer Press Insider has the concept art for the Hordes Minion Swamp Horror figure.
From their website:
This new heavy warbeast, the Swamp Horror, is an amazing addition to the Blindwater Congregation’s arsenal. I can’t wait to get it on the tabletop and watch my opponents cringe in terror as it rips through their lines. I don’t want to give away too much this early, so be sure to check out the Swamp Horror and all of the other awesome new hotness when HORDES: Domination releases this fall.
