Hell Divers V: Captives Audiobook
It was supposed to be a trilogy and many thought that the series would end in the third part but it was a wrong perception. The third part was just the beginning of the real action because the secrets were unveiled in that part. Xavier was thought to be dead a long while ago but he was alive and the reality was that he was left there intentionally by this friend who turned against him.
Then the Hell Divers finally found him and brought him back with a ship that they were in need of. Since then things became a little better for the remaining humans but it was not for a very long time. Xavier and Magnolia had to look for resources so they went to the Metal Islands.
Nicholas Sansbury Smith has shown a much more mature side of Xavier in this episode because he decides to lay down his arms instead of fighting against a powerful rival. The people of the place were warriors and they cannot be defeated easily so Xavier thinks that leaving his weapons is the best option for him. R.C. Bray narrates the condition of the people on the airship later on.
The Hell Divers present on the ship finally discover the Red Sphere and they are finally aware of the cause of the big war. There are also chances that another war of that kind take place once again and if that happens then the remaining humans will get killed in the process. Hell Divers X: Fallout is also present so keep in mind that this is a long series. Getting The Extinction Cycle Boxed Set would be a good idea as well because it is a box set so it has all the parts of the series in it.
