Voyeuristic hackers have undone its raison d'être and transformed the PC version of Mirror's Edge into the third-person parkour-em-up that could have been. Mind you, the one that could have been would have featured animation cognizant of the external viewpoint, and not just movements fit for first-person glimpses. It must have been a harrowing experience for those who expected to see Faith's nimble movements and instead received the lifeless posterior of a city-traversing robot.
You'll find instructions on how to coax the camera out of Faith's head at the On Mirror's Edge forums, and a video demonstrating the amusing trickery after the break. Mind the big spoilers after the 3:10 mark.
