Following last year's "Hyundai Undead" marketing campaign for the 2013 Elantra Coupe, the brand and agency Innocean have team up with "The Walking Dead" and its creator Robert Kirkman yet again. This time, it's to launch "The Walking Dead Chop Shop," an iPhone, iPad and soon-to-be Android app inspired by the show and comic book series that lets fan design their own survival machines.

While the first collaboration was for a specially designed "zombie survival" version of the car that came with its own manual -- currently priced between $275 and $3999 on eBay, this time, fans can get a little more personal, by picking out a Hyundai Elantra, Veloster Turbo or Santa Fe and then tricking it out with whatever might increase their life expectancy during a zombie apocalypse. The chop shop app comes just in time for the comic book series and has custom-designed add-ons including razor wire and flamethrowers and other authentic elements of the Walking Dead world. Fans can then see if their designs would make the cut by submitting in a contest in which the ultimate judge, Robert Kirkman, will review the concept and execution.

Speaking of personalizing cars, Volkswagen had previously done something similar with the award-winning "People's Car Project" which crowdsourced ideas for what cars of the future might look like.
