Need for Speed: Underground is the seventh game in the Need for Speed series and is the first Need for Speed game from the Second Era. Underground completely changes the Need for Speed series formula with a heavy emphasis on tuner culture and a storyline-driven career mode with influence from the movie "Fast and Furious". All races take place at night in a fictional city called "Olympic City" featuring customized tuners instead of exotics. Throughout the single player campaign, you unlock both visual and performance components which is key to being the fastest and most popular racer in the game. There is also a version of the game called Need for Speed: Underground J-Tune, which is only available in Japan on the PlayStation 2.
