Deus Ex: Human Revolution - Hands-on @ VG247

VG247 has a hands-on walkthrough of the first two hours of Deus Ex: HR, with input from Jean-François Dugas. I guess spoilers apply but obviously Eidos is using this early part of the game for marketing. The very beginning:

Human Revolution certainly doesn’t start like a traditional first-person shooter. No explosions. No thematically inappropriate wise-cracking soldiers. No Carmines getting shot in the head. Instead, the game kicks off by introducing you to an ideological conflict – that of augmentation and transhumanism versus purity and, arguably, humanity. Main character Adam Jensen follows his girlfriend – who’s recently made a major breakthrough in the field – through the sterile white Sarif Industries augmentation lab, and it’s there that the stage is set for the argument that will dominate the rest of the game. And who will win? Well, that’s for you to decide.

Over at Edge, there's an interview with Mary DeMarle about writing DX:HR.

In the opening cinematic to Human Revolution we hear a shadowy cabal discussing the fate of certain characters. Are we right in thinking there are some familiar voices there?
You might be right! But I’m not going to go any further than that.

If they were familiar voices, how far can you revisit [or pre-visit] Deus Ex’s characters without hitching yourself to their fate?
I’m often asked: “If you’re going to write a story that allows me to change the future, how can you make it a prequel when I already know what happens in 2052?” My answer to that is: “The world can change overnight”. When 9/11 happened, the world changed overnight. And we have 25 years between our story [in Human Revolution] and the story of Deus Ex to make that happen. At the same time – and maybe this is more what you were trying to get at – the original Deus Ex does have specific characters that we want to touch upon and events that we’d like to foreshadow, and we have to do that very carefully, because we don’t want to contradict what is canon. But, at the same time, with this story that’s 25 years before, what struck me was thinking, where was I 25 years ago? I was in college or high school, or maybe younger – I don’t want to date myself here! There’s not a whole lot I could have been doing 25 years ago, so which characters in Deus Ex could really have been a factor? We have to take all of that into consideration.
