It’s the year 3125 and the climate has changed dramatically and humanity cannot survive outside. The weather is just unstoppable tornadoes, earthquakes, tsunamis, hailstorms, blizzards, hurricanes, wildfires, mudslides and floods happen every day around the hole world and the temperatures are below the survival rate. So humanity now live deep inside the earth to protect themselves. It all started back in 2096 but as you can imagine humanity always find a way to survive. No one has ever been out underground before since then. You had to go outside with protection suits from the harsh environment. Your job is to fix the thick metal doorway in the ground to get in the underground homes. As you work hard with your teammates you hear a loud siren go off as everyone starts screaming and running back to get in the big mental door to take cover from a blizzard that is starting you were about to run but you suddenly got stuck.
