Boom Chaka Laka was an expansion set sold as boosters for the Shadowfist game. The set perfectly captured the style, movies, and music of the 1970s. Blurb from the booster box: "The 1970s. It's cool! It's hip! It clashes! And the Secret Warriors find themselves clashing in a big way. Superfly martial artists, dirty cops, nefarious hoods - it's one big throwdown in San Franciso's Chinatown. So strap on your Saturday Night Specials and boogie on down to the fight, cause the Jammers are about to take Disco Inferno literally!"
