District is a small underground town abandoned long ago due to an earthquake. Floors shattered and rocks scattered everywhere leaving everything in ruins. Some villagers attempted to return hoping to start living like they used to once again; however they couldn't. An obstacle no man could counter has stood on their way. It was quick and bloodthirsty and whoever approached it went missing. A group of super soldiers have been sent there to investigate the area and come back with a report. Alive.
