I don't know how I missed this one, but Ubisoft has announced Watch Dogs, a completely new game from the game developers. It took E3 by storm and amazed many gamers alike.
After watching the gameplay it looks to me like a mix between GTA and Heavy Rain. It's set in third-person and is a mix between action and stealth. You play a character whose job is to assassinate targets.
From the trailer you it states there is a central computer and if there is someone clever enough to hack it, which the person you play is, you can control a lot of the systems.
There's not too much information on the game yet because it's in early stages. It will be coming to PS3, Xbox and PC but word is that the next-gen consoles are coming out soon, which Ubisoft will take full advantage of.
