Gangs are criminal organizations found throughout Empire Bay. The city is Mafia controlled though other smaller street gangs operate within the city each controlling there own territory.
Gangs each have there own territory which they roam and protect. If the player holds up a store in a gang controlled area and a gangster sees the player they will try and kill the player. If the player gets a gun out in a gang controlled area gangsters will pull there guns out and warn the player to put it away.
