Description from the publisher:

Once simple rats, the Hell Vermin have become deformed and twisted by the raw evil of the Darkness. These beasts have grown giant, sprouting multiple heads, a ridge of nasty spikes along their back, and a massive barbed tail to lash at their enemies! Their fangs drip with shadow and hate, corrupting those that are bitten, while their bodies mend even the most grievous of wounds. Only from the pits of Hell could such fiends be spawned!

The Shadows of Brimstone: Hell Vermin Enemy Pack — which debuted at Gen Con 2015 under the name Shadows of Brimstone: SECRET Enemy Set #1 — contains everything you need to add the snarling mutant Hell Vermin to your games of Shadows of Brimstone! There are three large Hell Vermin models included, as well as the large Enemy Record Sheet and all of the Threat Cards needed to add them to your games.
