InFamous: Second Son is an upcoming game for the upcoming PlayStation 4, and the third installment in the inFamous series. It features a new setting, a new protagonist, and a seemingly-totalitarian government controlled by the police. It is set seven years after the world of Cole MacGrath and stars a new protagonist, Delsin Rowe.
InFamous: Second Son was first announced at Sony's PlayStation 4 Press Conference on February 20th, 2013, after officially announcing the successor to the PlayStation 3.
Sucker Punch's Nate Fox first announced InFAMOUS: Second Son at Sony's PlayStation 4 press conference. Fox described a world under government observation and control and then asked what would happen if citizens suddenly received super powers. The trailer revealed a city run by police, with a citizen running from the police through an alley before they turned around and used some sort of power to destroy an armored vehicle, along with using the chain wrapped around his right wrist as a weapon.
Set seven years after the episodes of Cole MacGrath, Seattle has been locked down by the Department of Unified Protection (DUP), an organization that handles any sort of bio-terrorism to ensure that the events of Empire City and New Marais don't repeat themselves.  It was also revealed that the DUP renamed Conduits into Bioterrorists and have been rounding them up, jailing them and possibly killing them. It was revealed that the developers assumed the good ending of InFAMOUS 2 as canon and that, rather than the RFI destroying all conduits, some survived based on their resistance to its effects and distance from New Marais.
As in inFamous and inFamous 2, Karmic choices play a role in the main story. The protagonist, Delsin Rowe, has the ability to absorb other Conduits' powers, replacing the electric-based powers of Cole MacGrath from InFamous and InFAMOUS 2 with multiple others. Every power that Delsin gets drastically changes the way the game is played.
Elements under Delsin's control (smoke, neon etc.) are absorbed from sources by pushing both thumbs on the DualShock 4's touch pad. The powers can be switched by absorbing their corresponding element.
Destruction has been greatly improved from the past games. More objects can now be destroyed, and if they are, they will stay destroyed for the rest of the game, unlike in previous inFamous titles.
