Twisted Metal Small Brawl Codes Codes and Unlockables (PSX)

Twisted Metal: Small Brawl is a vehicular combat game that was released for the PlayStation video game console in 2001. It is the sixth game in the Twisted Metal series. Unlike the other games in the series, Small Brawl was directed at a younger audience, but kept a good amount of comic violence intact.
