Producer Tom Ferrer explained to EGM Magazine that the time trial portions of Mirror's Edge will be "bite-sized and short so you can grind them and play them and get faster and faster. It's not like playing an entire level." Naturally, you'll be able to upload your fastest time for each section to online leaderboards, and you can even download ghost data that appears in the game as a stylish red silhouette showing how other people completed the task.
