Head to the pawnshop marked in the map to buy some Crafting components. If you’re not crafting anything yet, you may view the Hacking tutorial. Otherwise, you have to head to a new district where you need to intrude another ctOS Control Center in Brandon Docks.
Like before, you can head in and wreck the place with the use of your Hacking abilities then finish off the enemies using your weapons. The area is wide and has a lot of cover that will allow you to move in steathily. You have to find the guard with the access code so that you can hack in to the mainframe. Once you’ve found the guard, hack the code from him and hack the ctOS router inside the room in the middle of the area.
Once you’re in, you have the option to hack the other servers to view some surveillance video. The control center mainframe is located to the right so you have to take control of the laptop camera to get a proper view. After successfully unlocking it, Brandon Docks ctOS Towers will be revealed and the mission will be complete.
