Human Meta-Human Vampiric Virus

Human Meta-Human Vampiric Virus, commonly called HMHVV, is used in the game Shadowrun. The virus has been known to cause changes which often result in bandersnatches, banshees, dzoo-noo-quas, goblins, vampires, wild fomorians, wendigo, and other fierce abominations that are no longer human and are occasionally not even sentient. It should be noted that in the Shadowrun universe, vampires and their kin are not undead, but are changed by the retrovirus into a creature needing the life energy of others to survive.
