Siliconera: "In a behind closed doors presentation, Mary DeMarle, Writer, presented a small portion of Deus Ex: Human Revolution. The room was dimly lit with books scattered on the floor. I could have sworn there was a baseball bat there too. I took a seat behind a couch plus fortune cookies, which were on a coffee table. Square Enix was serious about decorating this room considering their Kingdom Hearts area just had wallpaper or Sora and the Birth by Sleep cast. DeMarle started the demo by emphasizing four gameplay styles: stealth, social, combat, and hacking. It’s up to the player to decide, which one to use."
