Welcome to Endtown, a community of animal-like mutants and “impure” humans infected with a mutagenic virus living below Earth’s post-apocalyptic surface. Driven by hunger, they venture out only in search of food, but must face bloodthirsty, mutated monstrosities and the constant threat of the Topsiders; un-mutated, technologically advanced humans bent on exterminating all mutations in order to create a genetically purified humanity.
