Imagine nuclear war broke out and wiped out almost every living thing on earth. Almost every living thing. Against all odds, you survived. You volunteered to be one of hundreds of people that would be stored in Cryogenic-chambers and awakened centuries later. That's what happened to Subject A-97B, also known as Ryan Gen. He was born on August the 1st, 2078. A little while after he was born, the war broke out. He survived in a bunker, and was one of the few who remained on earth. His parents gave him in, and he was raised in a radio-proof facility. That was his past life, and he had to move on. Centuries later, Ryan was one of the only ones to survive in the facility. From there, with almost no guidance at all, Ryan has to push himself to the breaking point, mentally and physically, in order to not only save himself but also other survivors he meets along the way.
