Dreadnought Nurgle version

Take a walking war machine, the kind built to carry a mortally wounded champion on into another few centuries of fighting, then hand it over to the plague god, and this is roughly what comes back. The hull has gone soft and distended where it ought to be square, the armour swells rather than sitting flat, and whatever remains sealed inside has evidently stopped objecting to its condition. It fills the heavy walker role in a Death Guard force or any plague-themed warband: slow, appallingly durable, and a nuisance to shift off an objective. As a painting subject it is a gift, since decay and corrosion reward patient work in a way that clean armour never does. The model comes as a multi-part kit. One properly grotesque centrepiece to anchor ranks of tidier marines.
