Watch Dogs Legion has 4 Sabotage 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 Sabotages require you to interact with the marked devices in hostile areas. You can easily fly to them with the Cargo Drone easily.
Sabotage #1 – City of London
Go to the red sabotage icon and interact with the console. An easy way to get there is to ride on top of a Cargo Drone (Construction Workers have this skill).
Sabotage #2 – Islington & Hackney
Hack the console marked in red. The easiest way to reach it is by flying to it on top of a cargo drone (Construction Worker skill).
Sabotage #3 – Southwark
The red Sabotage Location shows the exact spot of the console you must hack. It’s in a hostile area. Simply climb over the outer walls to enter the compound, clear out the enemies and then hack the console.
Sabotage #4 – Nine Elms
Just like with other Sabotage locations, the easiest method is to use your Construction Workers Cargo Drone to fly directly to the Sabotage point. It’s where the red marker is on the map. There are some enemies here so take them out if necessary.
That’s all of the Sabotage locations in Watch Dogs Legion to liberate the different boroughs / districts.
