"Helldriver" (Well Go USA, not rated, DVD $24.98, Blu-ray Disc $29.98). Genre fans of Japanese zombie director Yoshihiro Nishimura ("Tokyo Gore Police," "Vampire Girl Vs. Frankenstein Girl") returns with this cheesy, blood-letting action film. Japan is divided by a fortified wall that separates north— where the flesh-eating zombies prowl — and south — where their potential food supply must stay on the alert. A slapdash gang of dropouts led by Kika (Yumiko Hara), a beautiful high school girl armed with a chain saw sword, is recruited by the government to invade the dead zone and exterminate the zombie queen, or something like that. Extras on the Blu-ray include three short spin-off films and a director's introduction.
