Day Zero

by James Swallow

2020

A prequel to Watch Dogs: Legion, Day Zero shows London sliding toward the bombing that frames DedSec. Hackers, private security, and political fear collide as the city becomes a battlefield.

Series background & context

Watch Dogs: Legion is set in a near-future London shaped by surveillance, private security, hacking, and resistance. The city is the point. Cameras, networks, drones, and police power are everywhere, and DedSec fights back by turning the system against itself.

James Swallow co-wrote Day Zero, a prequel to the game. It sets up the attack that frames DedSec and helps explain how London slides into the state players find in Legion.

This is a good pick if you like cyber-thrillers with a civic edge. The hacking matters, but so does the question of who controls a city when fear becomes policy.
