According to the modder, it's an exact 1:1 scale version of the original map.
Using Dying Light's resources, modder Elimina is currently in the pre-alpha stage of their work on the Mirror's Edge prologue map (via Kotaku). A modder has been working on the prologue to EA's first-person parkour game, and it's looking pretty good so far. A part of Mirror's Edge has been recreated as a custom map for Dying Light.
