Oh god, not zombies. They'll bore us all to death with all the surviving miserable people and beards insistent on wandering into dark rooms with one door. It's a bloody zombie apocalypse, just stop doing that. A zombie apocalypse is no way to shuffle into damnation. Some kind of rapturously enthusiastic smiting maybe. Perhaps Cthulhu catching up with gangnam style and attempting to make some moves. Hey, it's a timeless void for the Elder Gods, you can't expect them to keep up with contemporary culture.
