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. 

Similar to its predecessor, Watch Dogs 2 is an action-adventure game with stealth elements and played from a third-person perspective as protagonist Marcus Holloway, a young hacker, the game features an open world environment set in a fictionalized version of the San Francisco Bay Area, an area more than twice as large as the Chicago setting from Watch Dogs.

The Bay Area consists of four different areas: San Francisco, Oakland, Marin, and Silicon Valley, all of which have different characteristics and aesthetics. Players can navigate the game's world on-foot or by the various vehicles featured in the game. 

The player can use different methods to approach the game's missions, choosing between the aggressive approach, in which they defeat enemies with guns which are made with a 3D printer. Alternatively, the player can use the stealth approach, in which they can evade enemies or paralyze them temporarily with Marcus' taser. The player can also complete the game through hacking alone. When the player commit too many crimes, the police officers will become alerted and will attempt to arrest the player. 

The game upgrades system is a returning feature, with items being divided into three categories: Ghost, Aggressor, and Trickster. The player can choose their upgrades in accordance with their own playstyle.
