Deus Ex: Human Revolution - Preview @ Worthplaying

Worthplaying has kicked up a new preview of DX:HR as the release gets down to three weeks or so. A snip of that describes the early gameplay, although I'm not sure why it is inspired by MGS rather than just the original DX:

For the stealthier folks, Deus Ex: Human Revolution could almost be inspired by Metal Gear Solid. Because each area is designed with multiple passages, it is possible to avoid almost every enemy. This is done by staying out of sight through a combination of smart cover usage and looking for alternate paths. Here, vent covers and air ducts allow us to pass undetected.

At the end of the warehouse level is the game's first real persuasion test. In facing off against a terrorist with a hostage, you have to attempt to talk him down. This is done by choosing to respond with a certain tone, such as sympathetic, and seeing how he reacts. Read your opponent well, and you can convince him to give up the hostage without spilling an ounce of blood. We've been told by Square Enix that it is possible to mess up a conversation and not get the desired result if you misread someone's reactions. In that case, the issue is permanent. You can't just go back and try again.
