The game's story focuses on the efforts of the London branch of hacker group DedSec in combating an authoritarian regime that has taken control of the United Kingdom, thanks to the advanced surveillance system known as ctOS. To assist in this, DedSec recruits allies from across the city in order to liberate the city as a resistance force. Each character in the game will have their own background and skillset and provide a more dynamic influence on the game's narrative as the story progresses.
