The Introduction is a roughly 20 minute video, created with Grand Theft Auto: San Andreas' video engine, that details how events in Grand Theft Auto: Vice City led to events in GTA San Andreas. It was available with the American PS2 Special Edition of GTA San Andreas or the official soundtrack double CD. It is set in 1992, and replaces the need for a GTA San Andreas Stories prequel, like Grand Theft Auto: Liberty City Stories and Grand Theft Auto: Vice City Stories (each explained the events leading up to Grand Theft Auto III and GTA Vice City respectively). The video ends directly at the beginning of GTA San Andreas, when Carl Johnson arrives in San Andreas after hearing the news about his mother's death.
The video can be now watched and freely downloaded at Rockstar Games' official website in .wmv or Quicktime format.
