镜之边缘
A new downloadable map for the game's time trial mode was exclusively released on the PlayStation Store for PlayStation 3 users on January 29, 2009. Seven additional time trial maps, which take place in surreal-looking stages outside of the game's city, were released for the PlayStation 3, Xbox 360 and Microsoft Windows versions of the game on February 19, 2009. This was followed by "Mirror's Edge 2D", a browser game adaptation by "The Fancy Pants Adventures" developer Brad Borne. A prequel to the game, also titled "Mirror's Edge", was released for mobile devices in 2010. Due to the use of the "Mirror's Edge" trademark, Electronic Arts was in conflict with California-based development studio Edge Games, who claimed the true legal ownership of the word "Edge" and its variations, including the phrases "Cutting Edge", "The Edge", and "Gamer's Edge". Ultimately, Edge Games settled with Electronic Arts and surrendered many of its trademarks on April 17, 2013.
