The latest in the "The Year 2027" series of Deus Ex: Human Revolution videos shows off a three of the cities that are featured in the highly anticipated prequel.
If you didn't know which cities you'll see in the game and don't want to know, stop halfway into the video. Everything up to that is talk about how they created the world and brought it to life.
If you look at the first 10 seconds, you can also see a plane with four engines flying at either low altitude or at high altitude in a really tall city. It appears to only have ten windows on either side; air commutes in the year 2027 must suck even more than they do in 2011.
