Mirror's Edge was an interesting design for a game that didn't really fullfill its expectation. However one of the cool things about the first person action game was its more surreal time trial levels that were released as downloadable content after the main game shipped to stores. Now a few enterprising folks at the Beyond Unreal forums have figured out a way to create a Mirror's Edge level editor.

Basically the procedure is coping a few Unreal Tournament 3 editor files into Mirror's Edge which is obviously not approved by either Epic Games nor the game's developer Digital Illusions. The move does seem to work well enough that a few new Mirror's Edge levels had been made. However messing with game files is always a risk so don't blame us if your game is broken afterwards.
