Velocity is a downloadable time trial map for Mirror's Edge. Unlike the time trial maps that come with the game, you are not in a city or planet Earth at all, you are actually in a big map full of floating bricks and blocks in a place with a blue sky like Earth. This map is a very difficult map for most new players, so a lot of practice is recommended before taking on any of the downloadable time trial maps. All of the maps require players to be able to quickly scan an area and jump without thinking but know they will be safe.
