A lurching, rotting monstrosity that befouls and taints the very ground it walks on, the Plague Hulk is a daemon engine sacred to Nurgle, the Chaos God of Decay and corruption.

Designed by Sean Green and Phil Stutcinskas, this huge, nightmarish fusion of bloated daemon-thing and Chaos Defiler is redolent with the marks of decay and corrosion as you can see here. It will make a fantastically characterful addition to any army devoted to the Plague God, not to mention a great painting project in its own right thanks to the model's lavish (if unpleasant!) detail.
The Plague Hulk of Nurgle is a hybrid kit using resin components and elements from the plastic Chaos Defiler kit and sold as a complete model.

We should have a limited supply of this model available at Games Day U.K., and the model will go on general release later in the year.
You can find experimental rules for the Plague Hulk here.
