A video game show built a perfect replica of "The Pit" from the Modern Warfare 2 Campaign. They then got a real operator to run through the course with a live weapon to time how fast he could do it. And meanwhile they have another guy in a tent play the same level with a 360 and time
him how long it takes.
Heres a link to the video.
