Vigilante 8 Passwords and Unlockables (PSX)

Vigilante 8 is a vehicular combat video game released in 1998 for the PlayStation, Nintendo 64, and Game Boy Color. It is a spinoff of the PC game Interstate '76, and features several concepts (auto-vigilantes, the 1970s time frame, and specific fictional vehicle companies) carried over from that title. Vigilante 8 was developed with a team of only five people (Peter Morawiec, Adrian Stephens, David Goodrich, Jeremy Engleman, and Edward Toth), a seemingly impossibly small team size for developing a PlayStation game, when most development teams for such a console ranged around 20-30 people in the 1990s.

A third game in the Vigilante 8 series was announced for PlayStation 2 early in the system's life cycle, but no further information or game was ever released. The developer of the two Vigilante 8 games, Luxoflux, produced a game very similar to Vigilante 8 using the Star Wars licesce (and the Vigilante 8 game engine), titled Star Wars: Demolition, and has since produced the Grand Theft Auto-inspired True Crime: Streets of LA.
