Deus Ex: Human Revolution's Adam Jensen doesn't have to be a cold-blooded killer. Using a combination of stealth, technology, and social skills, Jensen can go through the entire game only killing bosses. Narrative game designer Mary DeMarle shows us how.

There aren't many games that give you the freedom to play as you want to play like Deus Ex: Human Revolution will. Many action role-playing hybrids will allow you to put points into a stealth or persuasion skill, but at the end of the day you're still going to end up shooting the place all to shit in order to get the job done.

As Eidos Montreal's Mary DeMarle demonstrates, with a bit of planning and quick thinking, Deus Ex doesn't have to be a blood bath.

At least not on every play through.

Deus Ex: Human Revolution hits the Xbox 360, PlayStation 3, and PC on August 23.
