Time trial & free roam map for Mirror's Edge featuring HDR lighting and global illumination similar to the maps that shipped with the game. To play, unzip the "Published" folder along with the stuff in it to your (My) Documents\EA Games\Mirror's Edge\TdGame folder. To play the free roam, open the training area level in story mode. To play time trial, open up map "playground one" in time trial mode. When you're done, delete the Published folder that you've unzipped, and the levels will be back to normal (though if you get a time trial time, it will likely be saved - make a backup of the Savefiles folder to avoid this).
