Beacon of Life

Year 2014, 2 years after the great purge of planet earth by an unknown alien race, survivors across the world are now living in what they called it "Life Pods". Each Pod can sustain 2 million people, and there are hundreds of pods established across the world. They built it for the purpose of sustaining life after what they believed was the apocalypse, the end of the world at 2012...but no one was expecting an invasion.
