A group of zombies walking through a foggy forest at night

They would have the ability to fly, thanks to their extraterrestrial origin, and also the terrifying ability to turn humans into zombies, due to their undead nature. The invasion would begin silently, with the arrival of unidentified spacecraft that would descend on the most remote locations on Earth. The first to be affected would be the animals and people living in these isolated areas. Slowly, the infection would spread to the cities, causing panic and chaos. The world's military forces would be mobilized, but their conventional weapons would be ineffective against these zombie aliens.
