Tony Hawk's Underground is a skateboarding-adventure video game published by Activision in 2003 and 2004 as part of the Tony Hawk's series. Neversoft developed the GameCube, PlayStation 2, and Xbox versions, while the Game Boy Advance adaptation was developed by Vicarious Visions and the mobile phone version by Jamdat. Players explore levels and complete goals while performing skateboarding tricks; players can also create a custom character instead of selecting a professional skater. The plot follows the player and their friend Eric Sparrow as the two become professionals and grow apart. The game was developed with a theme of individuality, and real-world skateboarders contributed their experiences during development. Reviewers praised its wide appeal, soundtrack, customization, multiplayer features, and plot. The graphics and the controls for driving vehicles and walking were less well received. Underground's PlayStation 2 version had sold 2.11 million copies in the United States by December 2007. A sequel, Tony Hawk's Underground 2, was released in 2004. (Full article...)
