In 2013, during the mission Sometimes You Still Lose, after he hacked three access points across the city, Aiden Pearce went to the tower's lobby to temporarily shut down the entire CTOS network via a satellite. He received a quick call from DedSec through one of the TVs in the lobby, asking him to let them inside the CTOS. He refused, and went on to plunge the whole of Chicago into a blackout.
