While exploring the caves, survivors were finding abandoned hangars that contained something indeed unbelievable: relics from the past - the DigTrains.

Now the hum and noises of mining equipment are heard from every nook and cranny. They established free trade of all the materials gathered underground. They called themselves Free Cities Union - the coalition of settlements that was made to protect its citizens. People had found their new home in the very depths of the earth. Humanity had been hiding in shelters and bunkers until everyone was safe again. It has been ages since the Great Catastrophe.
