While it was originally thought to have killed all Conduits across the globe, some Conduits proved resistant to the device due to the long distance from New Marais. The developers assumed the good ending of Infamous 2 as canon and that, rather than the RFI destroying all Conduits, some survived the explosion. forced many Conduits out of hiding by turning the general public against them, and sent them to Curdun Cay, a prison designed to contain and experiment on Conduits. Using propagandized messages via news and public services, the D.U.P. renamed Conduits " Bioterrorists" and have been rounding them up. Fearing the Conduits' abilities, the United States forms the Department of Unified Protection (D.U.P.), an organization that handles any sort of bio-terrorism to ensure that events similar to those of Empire City and New Marais do not happen again. The game is set seven years after Cole MacGrath activated the Ray Field Inhibitor (RFI) to destroy a Conduit (a superhuman named for their ability to channel powers) named John White AKA the Beast and cure the Plague, sacrificing himself and the conduits alive then. The trailer revealed a city run by police, with a citizen running from the police through an alley before he turned around and used some sort of power to destroy an armored vehicle, while using the chain wrapped around his right wrist as a weapon. Fox described a world under government observation and control and then asked what would happen if citizens suddenly received super powers.
