Deus Ex: Human Revolution is finished, and the clock is ticking until we get to play it. But don’t watch a clock, that’ll make time go slower. Yep, if everyone in the world watches clocks at the same time, then time is actually paused. Little know fact for you there. Anyway, the game being finished hasn’t stopped Deus Ex’s video mill cranking out more and more stuff for us to watch, should we wish to get even more excited. The latest of these is a video (below, via Blues) which highlights the stealth and non-lethal aspects of the game. It’s all about sound propagation, stun-guns, and listening in on other people’s conversations.
