the most-surveilled city in America. The developers noted that character movements in games like Assassin's Creed were the same in every situation, and attempted to rectify this in Watch Dogs to contextualize protagonist Aiden Pearce. The in-game control system ctOS was based on the SCADA system, and the story was inspired by the cyber-attack by the computer worm Stuxnet on SCADA. The developers consulted the cyber-security company Kaspersky Lab (which discovered the Stuxnet worm) about the hacking features to increase their authenticity. To create hacking factions in the game (like DedSec), the developer was influenced by the hacktivist group Anonymous, state-sponsored hackers, and tales of corporate espionage.
