Dark Horse Comics is attempting to unite the rather jumbled yet interconnected universe of "Alien," "Predator," "Aliens vs. Predator" and "Prometheus" in an ambitious crossover comic series event. Things kick off next month with "Prometheus: Fire and Stone," which is set after the events of Ridley Scott's 2013 sci-fi film. In the comic, a new team heads to LV-223 to learn the fate of the Prometheus, and there they uncover a dark mystery.
