Watch Dogs Legion has 2 Digital Deface locations. This guide shows how to complete these oppression challenges (borough activities). They are marked by red icons on the map. Completing all of the red activities in a borough / district is required to liberate it for the Take Back London trophy or achievement. Each of these you increase the DedSec support in the borough. This in turn makes people easier to recruit. When a district becomes defiant it also marks all Tech Points on the map and unlocks a unique Skilled Recruit.
It’s highly recommended you play as a Construction Worker. You recruit one automatically early in the story during “Reporting for Duty”. The Construction Worker’s Cargo Drone allows you to fly everywhere and get to hard-to-reach places with ease. Simply select it from the item wheel, hijack it, park it on the street, climb on it and fly up.
The Digital Deface challenges require you to reach consoles high up on buildings.
Digital Deface #1 – Southwark
Simply fly to the Digital Deface location using a Cargo Drone (Construction Worker skill). Summon Cargo Drone from Construction Worker’s item wheel, hijack it, park it on the street, climb on it, hijack it again and fly up while sitting on the drone.
Digital Deface #2 – Lambeth
On the rooftop of St. Thomas’ Hospital (Skyscraper). This is up so high that even a Construction Workers Cargo Drone can’t reach it. Instead, look for a Window Washing Lift on the side of the skyscraper. Lower it, get inside, and raise it all the way to the rooftop.
That’s all of the Digital Deface solutions in Watch Dogs Legion to liberate the different boroughs / districts.
