In the year 2989, New York City has become a melting pot of humans and various alien races. Sixty-two years ago, Earth opened its arms to other planets in neighboring galaxies by signing the Interstellar Pact. This allowed the people of Earth to colonize other worlds and in turn allowed aliens to migrate to Earth. Thus began perhaps the most violent period in American history. Inadequate living conditions and racial tension resulted in riots becoming an everyday occurrence across the country. Law enforcement agencies found themselves buried under overwhelming situations. Relief came with the landmark passing of the Extermination Act in 2931. This expanded the duties of exterminators from insects and rodents to aliens and mother-in-laws. Now exterminators are as prevalent in society as lawyers, bankers, and garbage men.
Roachmill is simply the best exterminator there is.
