In this gameplay trailer for Deus Ex: Human Revolution we get a glimpse of the Social and Hacking pillars of the game. Just like it sounds you can persuade people or you can hack into the systems. However hacking doesn’t just get you items but information about the world around you and can gives you a better understanding about the back story in the game. The social aspect can get you information as well but you will also be able to talk to someone to create a non-violent or alternate outcome for certain scenarios. Dues Ex: Human Revolution is really a play as you want game, from chess like mind play, all out commando style or anything in between.
