Mirror's Edge Afterthoughts from 1UP.com is a Q&A with Tom Farrer from DICE about Mirror's Edge, their parkour action game. They discuss the reasoning behind why things are done the way they are in the game, and along the way get a hint about an Easter egg: "There is one particularly odd one. There is something you can do on level 8 that causes a rat the size of a bus to run down the street. It is so obscure, though, so I doubt anyone will find it."
