Ten years have gone by and much has changed for the remnants of humanity that remain aboard The Hive. Leon Jordan is now the Captain and Tin has grown up to become the Commander of team Raptor. It is no surprise that he decided to follow in the footsteps of his father and X and become a Hell Diver since X's loss is still felt to this day. X may be gone, but he is not forgotten, and his final sacrifice has turned him into a role model that still gives people hope, which is in short supply. Captain Jordan has abandoned Captain Ash's belief that humanity would one day return to Earth and he is willing to do whatever it takes to convince the rest of the crew that the surface is forever lost. However, walking away from the dreams of so many people is bound to have consequences...

"We dive so humanity survives." That is the motto of the Hell Divers, who risk their lives to keep the final remnants of humanity alive. All remaining humans now live aboard massive airships that float above a storm covered, radioactive Earth, which has not been habitable for the last 250 years. These dated airships have only managed to stay in the air by regularly sending Hell Divers down to the planet below to scavenge the parts they need to keep their reactors running. Hell Divers, who have an average life expectancy of only 15 jumps, are composed of brave men and women willing to risk their lives by parachuting down through the storms to a toxic planet where they scavenge for items created in the past by a people they no longer understand.
