Mirrors Edge Easter Egg - Huge Rat Easter Egg (hilarious!)

This is totally insane and hilarious. Here are the instructions:

1) Go to "play chapter" and pick the level "Kate."
2) Select "Part D."
3) Grab the rifle and zoom in on the first corner the truck turns around.
4) When the truck comes, shoot it while it's coming around the corner. (You must hit it in the engine.)
5) Zoom out (just makes easier to see where you're shooting next), and look at the far building behind the street.
6) You will see two orange signs; zoom in on the right one.
7) You'll see nine white circles; shoot the one in the middle.
8) If done correctly, a huge rat the size of a car will run down the street.
