Need for Speed: Underground 2 is a street racing game and the first entry in the series to feature an open world environment. Set in the fictional city of Bayview, players drive freely between events while building their reputation through circuit, sprint, drift, drag, and Street X races, as well as outrun challenges and Underground Racing League tournaments. The game expands on its predecessor with broader vehicle customization options, a sponsorship system, and new race types. SUVs appear alongside the returning roster of tuner cars.
