In the course of the game you will get the chance to prank an internet troll and streamer who happens to play Rainbow Six: Siege on his computer. Hack into his system and call 911 to provoke a false shooting scenario, thus making an emergency lady to call an entire SWAT to get the internet troll.
This is probably one of the coolest easter eggs in Watch Dogs 2. It’s fun to see how a game can turn into reality in just a glimpse of an eye for somebody who doesn’t respect others. This quest is both highly entertaining and satisfying.
