Big Mutha Truckers 2 begins with Ma Jackson, the proprietor of Big Mutha Truckers Haulage, being taken into police custody for tax evasion. The only way she can win her case is by hiring Cousin Jacob, the most "fancy-talkin' legal fella" this side of Booger's Canyon. It's up to you to raise the cash needed to bribe jurors to let Ma off by trucking, trading, wheeling and dealing.
The go-anywhere, any-time philosophy that was utilized in the original Big Mutha Truckers is expanded for Big Mutha Truckers 2 with additional routes, hidden shortcuts, and the ability to drive numerous vehicles. In addition, the trading process has been extremely streamlined, with more focus on the on-road action. Also instead of just police officers & bikers, you also have UFOs that steal your load if you're not too careful. Unlike Big Mutha Truckers, Big Mutha Truckers 2, uses Free's "All Right Now" instead of Steppenwolf's "Born to Be Wild" for its theme song.
