South Korean car maker Hyundai recently helped create a one-of-a-kind vehicle as part of a marketing campaign (dubbed appropriately "Hyundai Undead") designed to highlight its 2013 Elantra Coupe as well as celebrate the 100th issue of the graphic novel series The Walking Dead. Developed with the help of Design Craft Fabrication, Hyundai unveiled its "Zombie Survival Machine" or "ZSM" at the annual "Comic-Con" convention in San Diego July 13.
