In the steampunk city of New Yorkshire, steam is power. Unfortunately, enormous trenches have opened in the oceans, the heat boiling them away. With no other way to provide power, the Horizon came into power and began secretly murdering anyone who reached the age of 30 and processing their bodies to extract the water. The scarezone opens as chaos has taken over New Yorkshire, with roaming bands of killers openly slaughtering and processing victims in the streets.
