Wisdom from the Wastelands (Issue 12 - Apr 26, 2012)

From publisher blurb:

Issue #12: Parasite Mutations/Transformations

Gut worms and intestinal bacteria, athlete’s foot fungus, toxoplasmosis protozoa, lycanthropy and Rage and vampire viruses. Whether biological fact or fictional terror, we are surrounded (and colonized) by parasitic lifeforms, some of which evolved to become a necessary part of us — while others affect our behavior, or become our nightmares. Parasite mutations were originally introduced in the Skirmisher Publishing LLC sourcebook Creatures of the Wastelands, but transformations are a new evolutionary step regarding the concept of symbionts bonding with hosts.
