A NEW ZOMBIE VIRUS IS UNLEASHED AND GROOT IS PATIENT ZERO! Groot feels bad – not only because Rocket’s latest scheme put them firmly in the crosshairs of the Avengers, but also he’s just plain sick! Sap-dripping nose and all. Things go from bad to apocalyptic, however, after an ill-timed sneeze in Captain America’s face has unforeseeable consequences! Suddenly, Groot is being attacked by a horde of zombified Avengers, and only he and Hulk, with his impenetrable green skin, remain impervious. Now it’s up to these two heroes to team up and fight their way through a blighted New York City to Banner’s lab in Avengers Tower to find a cure before it’s too late. But can Groot keep the hero in check and on track, or will Hulk unleash his deadly might on the zombies they once called friends?
