Or, to borrow a YouTube comment, Deus Ex: Stand-Alone Complex.
Level of detail looks a bit jacked up, in my opinion, but the gameplay itself looks interesting. It's unclear how much of that is open gameplay and how much is scripted stuff you have to do, like the signal-hacking in the latter part of the game.
Also it's disappointing the trailer ends up a shootfest eventually, because I was hoping this was going to be a case of smartness beating brawn, something like Mirror's Edge.
