Watch Dogs Legion has 2 Hack CtOS Hub 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 Hack CtOS Hub Challenges require you to interact with CtOS consoles and then complete a minigame with cameras. You will have to interact with certain objects while in camera mode.
Hack CtOS Hub #1 – City of London
To enter the area with the marked challenge, simply walk through the doors of the building (accessible from the street to the east). This leads you to a homeless shelter with a locked door. To open the door, hack the nearby drone (Screenshot #2) and fly it up the balcony above (Screenshot #3 – still inside the homeless shelter, not outside). You can scan the area by pressing R3 / Right Stick to see a key icon on the minimap. Up on the balcony there’s a datapad you must scan with the drone. This unlocks the key to open the gate. So go ahead and open it to find the CtOS console. This will trigger a minigame of sorts – you’ll be in a hideout where you can only use cameras. Press R3/Right Stick to scan the mannequins and / to jump between them. First, scan the main console after jumping to the first mannequin. It will show you that it requires a password. To get the password you must scan 3 computers around the room for text files (Screenshots #4-#6). So press R3 / Right Stick to scan the mannequin and jump between them using / to get to all 3 computers. After that you can hack the main console on the stage to finish this Challenge.
Hack CtOS Hub #2 – Southwark
Interact with the CtOS Hub on the rooftop where the red marker is. You can use a Construction Worker’s Cargo Drone to fly up there. Hacking the CtOS will bring up the camera of a plane’s cockpit. Here you must zoom in on two blue datapads and hack them for their data. This will reroute the plane and complete this activity.
That’s all of the Hack CtOS Hub solutions in Watch Dogs Legion to liberate the different boroughs / districts.
