New Ubisoft IP Watch Dogs Gameplay Demo
With Sony and Nintendo still left to go, so far Ubisoft is the clear winner of E3, even if only for Watch Dogs alone. This game with no platforms as of yet, the guy demoing the game was playing with a generic PC controller, looks to be the standout of the show.
Watch Dogs has apparently already been in development for 2 years. It seems to be a fully open world style game. The theme of Watch Dogs is that everything is connected, and you will be hacking it.
Here is the gameplay demo in full.
