Connection is power. Everything is connected. Everyone casts his digital shadow. As Aiden Pierce use hacking, surveillance and sabotage to send a message across the city.
Watch Dogs is just like Assassin's Creed and GTA made a baby, It is alot like of gameplay of GTA, the stealth system from Assassin's Creed, and the disadvantage, is the guns are so very underpowered for the Enforcers, the heavily armored guys, however, a 50 cal. or any explosive can kill it, isn't it weird? And the guns are so overpowered when using it from Gunmen to Veterans, since one hit of a ACR, .45 ACP, M8-8M, or any expensive weapons can kill them instantly, or one shot, one kill, You cannot use helicopters, which is really cool when you can use them, and finally, the strangest thing, you cannot use media app during a mission, also there is no gore, which is unlike any mature gta-like games but that doesn't matter.
The story is great, Aiden Pearce seeks out revenge for his niece, just like when Ezio seeks out revenge for his family.
