No, but they had a short talk about it at the end of last week's TWiT episode. It sounded like a great idea. Certainly one of the most original ideas to grace an FPS game in a loooong time.

I like the system that forces you to be occupied with certain things for certain periods of time. Like you have to eat and go to the bathroom, and you're vulnerable while you do. Apparently the most stressful thing in the game is sleeping, which takes 30 seconds and the screen is entirely black the whole time.
