A comet, which no one could notice, suddenly crashed into the Earth and raised a cloud of dust. It all happened in the desert and few people were injured. Everyone thought that trouble had passed us by, but that was just the beginning. The dust contained bacteria that turned people into zombies. When the cloud rose into the sky and set off to travel around the planet, it began to rain in some places, after which zombies began to appear there. You, as a soldier, were given the task of finding the dead and destroying them. All armed forces are raised to arms to deal with this infection in Zombie In Ruine.
