The Walking Dead universe isn't the only hot zombie property invading Comic-Con this week. The CW's iZombie, fresh off a killer third season, unleashed an awesome "story so far" sizzle reel video for the fans in attendance at the show's Q&A panel and we've got your first look at it. Take a brain-devouring stroll down memory lane as we look back at how iZombie basically transformed from a series where zombies were in hiding and Rose McIver's Liv Moore could lead a secret life where she helped the Seattle PD with unsolved murders, to a series where the world now knows that zombies exist and all hell is breaking loose.
