A preview of Tony Hawk's Underground for the Sony PlayStation 2, dated 48 days before the final build.


  • Only the first three levels (New Jersey, Manhattan, Tampa) are selectable. Through modding, the demo mode flag can be turned off and the full game unlocked. However, every level besides the first three, Moscow and the test level crash the game upon loading, albeit the existence of the level files on the disc.
    • To unlock the game, open the disc image in a hex editor and set the value located at 0x14F6420E to 00. Then edit the two references to startup.qb at 0x000DE9D2 and at 0x2DE3E4E7 to something else. Note that both replaced references still have to be consistent.
    • To unlock some of the additional levels like "West Side" and the test level, set the values at addresses 0x2DF1D592 and 0x2DF1D5A3 both to 01.
  • Has a second executable file on disc, dated July 30, 2003.
  • In the Story Mode you can only progress until Chapter 10. After beating the Tampa AM goal, the words "DEMO BUILD" flash on the screen a few times and you are unable to continue the story.
  • There are a few levels in the game files, that were removed from the final game. Notably, a level called "West Side" which is assumed to be a test level for Neversoft's later title Gun (2005) and an early scrapped level called "Australia"
  • Several of the game's hidden characters have not yet been implemented and instead show an unclothed, bald version of the standard CAS model.
    • Each skater in the character select screen starts off in a T-pose.
  • A lot of voice clips are missing and sometimes the player would switch male and female voices.
  • Some of the songs in this build appear in their uncensored form.
    • A track called "Can You Find" by Freestyle Fellowship is included, that did not make it to the final game.
