Replying...
Intro. You lived your normal life in the city, everything was quiet, families living happily and contentedly, people traveling from one place to another. But everything changed when climate change affected the electromagnetic field and the earth's glaciers, melting the ice and snow of Antarctica. Global warming caused forgotten viruses and creatures that were thought to be fantasy to be discovered by man. It all ended when in a matter of months millions of people lost their lives to a virus that scientists cataloged as "Alpha Proximus" which they believed would be a breakthrough in modern science... How wrong they were... Those who died from the virus came back to life in the form of zombies, zombies thirsty for blood and revenge, they were joined by giant spiders that were believed to be fictional. The oxygen became heavy, the earth adapted to this change as a way to get rid of the plague of humans.
