I bought this initially with the rulebook thinking it sounded very interesting. I was not disappointed. The new expansion not only adds more scenarios for greater variety of gameplay, it also adds a whole new warband with its own feel very unique to them over any of the other warbands. Especially compared to the traditional mutants in the core rules.
Think Texas Chainsaw Massacre, the Hills Have Eyes, Deliverance, and add in a nuclear war. This will give you the creepy, erie mutant cannibals. They're a disturbing group that kill, eat, and wear other wastelanders. They live in a "family" group which usually consists of a matriarch or patriarch, an old fart or two, and the scary ass kids who are either just slightly abnormal or downright degenerate. Then there's the pretty, normal looking girl whose job is to lure unwitting wastelanders into the dinner pot.
Well worth the cost, this supplement provides the rules, background, and new equipment for this warband that plays differently than all the rest. $5 for a new faction is well worth it, especially when it comes with new scenarios.
