Watch Dogs ctOS Towers play the most important role in the video game, because they allow you to reveal all collectibles, and side-missions within a district; therefore, while playing Watch Dogs, you have to focus on them as soon as possible.
On the other hand, some District ctOS Towers must be revealed first, by hacking the ctOS Control Center available in the same district. Unlike the ctOS Towers, the Control Centers are well protected and to breach one of them, you have to deal with all enemies around it.
After you locate a ctOS Control Center, if you get close to it, you will notice that you will enter a restricted area, clearly marked on your mini-map. Inside the restricted area, you will find multiple guards, and you will be asked to locate the access code owner and hack him.
The access code owner is one of the guards around the control center, and to identify and hack him you have two options.
You can try to use Aiden’s cell phone and hack the cameras within the compound, or you can directly engage the enemy forces. Eventually, if you kill all of them you will find the access code which must be used to hack into the server room and install a backdoor on the district network.
If you successfully disable a ctOS Control Center, you can reveal the locations of all ctOS Towers in a district, and you will also be able to use the Profiler while exploring the same area. In Watch Dogs you have to breach four ctOS Control Centers, in the following districts: The Wards, Brandon Docks, The Loop and Mad Mile.
All of them can be accessed during the first act of the game. The ctOS Towers in Watch Dogs on the other hand, are unprotected, but to hack one, Aiden must stand next to it.
Since the Watch Dogs ctOS Towers are located in places that might be hard to reach, in the following guide you will find useful information that will help you hack all of them.
Watch Dogs features 13 ctOS Towers that must be hacked for the Clear Signals achievement/trophy.
Additionally, if you hack all of them you will unlock the SMG-11 machine pistol, and the Amargosa Turbo speedster.
Just like the ctOS Control Centers, the ctOS Towers can be hacked during the first act of the game. The maps below show the locations of all ctOS Towers in the videogame, and they are marked by red icons similar to those on your map.
Once you identify the tower on the map, follow the instructions below to get close to it.
