We've known for a long time Watch Dogs would take players to Chicago, but now thanks to a new trailer we know more about the digital citizens that will inhabit it.

As detailed in the above video, Chicago's populace is an important part of Watch Dogs' formula. Ubisoft promises every NPC in the game can be hacked in some way, and each will have a unique identity that determines how they react to the world around them.

Any one of the game's NPCs could lead to hidden secrets or unexpected events, and any citizen could be a victim, a killer, or another player hiding in plain sight. Cross the wrong citizen, and you may find yourself with a bounty on your head.

Watch Dogs is releasing May 27 for all consoles except the Wii U version, which will be coming at a later date. Be sure to check out our hands-on impressions of the game here
