Vermin are large, spider-like ravenous scuttlers with a central thorax that seems to take the form of a screaming human head. Relatively weak individually, they become more dangerous in packs, and sometimes appear after “detaching” from a fallen zombie host: In a spray of blood, the head and some internal organs rip free of the skin and sprout legs. Keep your head on a swivel, lest you’re dropped on. Vermin sprint and jump to inflict damage, mouth wide-open with a wet growl. They’ve also been known to spit a caustic substance, but this is the least of your worries.

Vermin also have the potential to evolve into another form, emitting gas, elongating their skull thorax and changing into an airborne terror, the Parasite.
