Description:

Halloween has been infected.

This collection blends alien horror, biohazard terror, science fiction, mutation, and Halloween atmosphere into one twisted coloring experience. From contaminated laboratories and infected survivors to extraterrestrial creatures, hazardous wastelands, grotesque mutations, and sinister Halloween scenes, every illustration explores a world where an alien outbreak has transformed the season of fear.
