Ten years after the events of Crackdown 2, a terrorist attack from an unknown source kills power around the entire world. The Agency is thrust back into action after the attack is traced to the city of New Providence, controlled by the mysterious organization Terra Nova, led by Elizbeth Niemand.

The game was announced at Microsoft’s press conference at the Electronic Entertainment Expo 2014 in June 2014, as an Xbox One exclusive.

The game was officially revealed as Crackdown 3 during Microsoft’s Gamescom 2015 press conference on 4 August 2015.

In January 2018, Epic Games acquired Cloudgine, and with that, Jones left Reagent to join Epic Games. Polygon reported at the same time that several Reagent programmers also left to go to Epic.
