Stare into the Abyss

Like the other ctOS control centers, this area is heavily guarded. You must first find the guard that has the access code. You can either hack it remotely or retrieve it by knocking out or killing the guard. You can then proceed to sneak in to reach the security router or just wipe all the guards in the whole area. Once you have the view of the server room, you can view the footage from the servers if you want or just unlock the access point.

Once you start the campaign mission, head to the marked security router and hack it. Once you get inside the security camera of the building, you have to find and profile Crispin. Once he's tagged, make sure you have a vehicle nearby since Crispin will try to escape at the first sign of trouble. Take out his guards then chase him down and kill him. Hack his phone to know your next destination.

Go to the underground club and follow the host. After the scene, head out of the club and you'll find a new ride for you. Mission complete.
