Survivors range from, but are not limited to, a series of victims that the Protagonist encounters and can optionally help, or a group of hostile gangs that seek to take whatever they can get their hands on and occupy a great majority of the fortified locations. There are also cannibals that live underneath the city in the subway that feed off their fellow man and the rodents that occupy the desolate environment, though for the most part they seem to be fairly docile as few will attack the Protagonist.
During the height of the Event, the residents of Haventon scrambled to reach the boats and evacuation teams that would take them to safety. As a result of the mass hysteria, many people were killed or were unable to escape. In the aftermath, survivors of the ruined Haventon fell prey to their fellow man or the deadly environment made more perilous by the toxic dust cloud.
