Square Enix released not one, not two, but three trailers this week for Deus Ex: Mankind Divided. The first shows off the game, including a look at the story, gameplay, and just gives a good general overview like most trailers tend to do. The second is a tech demo video that shows off the graphical eye candy that is coming to Mankind Divided thanks to the Dawn Engine. The last video is a behind the scenes video with the developers talking about "visual works."
