It's the alien apocalypse. The world is at war with aliens from another galaxy. The U.S. military has issued that every citizen is to report to a huge bunker that they created. Most people have made it to the bunker, except for a few, including you. You run down the streets, running away from aliens shooting plasma bullets at you. You run into a house, and you lock the door. Suddenly, somebody grabs you and pulls you down. "Shh! The aliens will hear you!" It was a woman with a rifle.
