Pernicious Invaders

Your body ... the food you eat ... the environment around you ... whether it be insidious organisms or deleterious chemicals, there are things among us that can quietly turn our serene life into horrors of despair. Within your hands is an anthology of nightmarish and inconceivable horrors in which foreign entities bring the world around them to a halt. Mutations, death, and famine! The destructive apocalypse! People decomposing before the eyes of their neighbors while others turn into a host for parasitic beings!
