Tony Hawk's Underground 2 is the sixth installment in Neversoft's Tony Hawk's Series and sequel to Tony Hawk's Underground. Tony Hawk's Underground 2 was released on October 4, 2004 for the PlayStation 2, Xbox, GameCube, Microsoft Windows and Game Boy Advance platforms. The game is partly based on season 2 of Viva La Bam, although there are many references to Jackass.
Although not the first game in the franchise to be released in a seventh generation console, Underground 2 is also forwards compatible with the Xbox 360. On March 15, 2005, it was released for the PlayStation Portable and renamed Tony Hawk's Underground 2 Remix, to indicate the addition of several extra levels.
