Mack and the proven valorous crew of the Onyx Raptor are finally going home, despite knowing full well that this is shaping up to be far from a welcome homecoming. As they had predicted, the Lithuundu arrived upon Earth weeks ahead of them, looking for a species to enslave. Unfortunately for the human race, they predictably end up sparking a new alliance with an old enemy, a notably lurid man who is coincidentally dying for a chance to live forever. Due to the tyrannical alien threat upon Earth’s last shreds of humanity, the crew of the Onyx Raptor are now forced into the final battle for Humankind, on their own irradiated, war-torn soil. Where humanity itself, and the promise of hope, was all but lost decades ago; only to rise from the ashes once more.
