Deus Ex: Human Revolution Revealed, Trailer Released

As twice promised, IGN has an information blowout on Deus Ex 3, revealing its title (now officially Deus Ex: Human Revolution), a teaser and a two-page interview with Game Director Jean-Francois Dugas.
Can we be expecting a role-play game like the earlier Deus Ex games have been, or simple lineal first person shooter? - tyxor

Jean-Francois Dugas : Deus Ex: Human Revolution uses the first Deus Ex game, which perfectly married the first-person shooter and roleplaying game, as its reference point, so you can expect an experience similar to it. The goal is to deliver the perfect mix of both genres, giving players the option of choosing to play the game depending on their preferred play style. The game is built around a multi-path, multi-solution approach so you often have more than one way to pass an obstacle, and within that you have tonnes of options for character and weapon customization.
If your preferred play style revolves around combat, there are plenty of augmentations and weapon customizations to transform you into a killing machine. If you're a strategist or a pacifist, there are several options as well to avoid confrontation through augmentations and other means. The choice is yours.

I remember the first game being completely open ended, If I wanted to try and kill an important character, I could do so, even if the character would probably be too powerful and kill me first. It made me feel like I had choices even when in reality i didn't. Is the game going to pursue these open ended decision making elements of the first game? If so does this mean it will be a game with multiple paths to follow such as a game like heavy rain? - TheB-Rad-G

Jean-Francois Dugas : I'm currently playing Heavy Rain and I must say this is a fantastic experience. Even though Deus Ex: Human Revolution shares similarities in terms of "choices & consequences", we offer a totally different game experience. But, yes, we want players to make choices that will affect some outcomes (story-wise and gameplay-wise).

Like the first game, our game world is designed around a multi-path, multi-solution approach so any objective can be approached in different ways. Whether you like action, stealth, hacking, or interacting with characters, you can complete objectives in different ways.

The two primary gameplay styles are combat and stealth. You can basically play the entire game by going "frontal" or by going "sneaky" and/or back and forth as you please. For us, it's really about letting players express themselves the way they want. You can decide to play the game without killing anyone (minus some critical encounters), for example.

The two supporting gameplay styles are hacking and social interactions. You can expand your possibilities through these means in order to open up new paths, find new solutions to problems, acquire useful goodies or information, etc.

Open-ended gameplay allows the player to take advantage of multipath/multi-solutions to accomplish their objectives and explore the game world for side quests, hidden treasures, etc. Some RPG dialogs will be mandatory but most will be available to players in an optional form. Obviously there are benefits from a story and gameplay standpoint to talk to other characters but it's not forced. If your play style is more centered on shooting, then so be it.
This method also rewards multiple play-throughs since by choosing one method over another, you may miss some interesting things that are accessible only by attempting specific things!
