Watch Dogs 2 (stylised as WATCH_DOGS 2) is an action-adventure video game developed by Ubisoft Montreal and published by Ubisoft. It is the sequel to 2014's Watch Dogs and was released worldwide for PlayStation 4, Xbox One and Microsoft Windows in November 2016.

Set within a fictionalized version of the San Francisco Bay Area, the game is played from a third-person perspective and its open world is navigated on-foot or by vehicle. Players control Marcus Holloway, a hacker who works with the hacking group DedSec to take down the city's advanced surveillance system known as ctOS. There are multiple ways to complete missions, and each successful assignment increases the follower count of DedSec. Cooperative multiplayer allows for competitive one-on-one combat and connecting with other players in order to neutralize a player who is causing havoc.

Ubisoft Montreal, the game's developer, studied player feedback from the first game to assess what could be improved in Watch Dogs 2 and the setting was researched by making frequent trips to California. Ubisoft Reflections was responsible for overhauling the driving mechanic. Real hackers were consulted to validate scripts and game mechanics for authenticity and references to real life hacktivism were fictionalized, like the Project Chanology protest. The original soundtrack for Watch Dogs 2 was composed by Hudson Mohawke.

The game was released to generally favourable reception and praised for improving upon the original Watch Dogs in areas like the hacking, setting, characters and driving. However, character inconsistencies, firearms and frequent technical issues – later patched – were cited as imperfections.   - Wikipedia
