The Callisto Protocol DLC, titled Final Transmission, plunges players back into Black Iron Prison as an audio log detailing a scientist's desperate final moments. It reveals more about the horrifying biophage outbreak and the shadowy UJC's experiments, using claustrophobic corridors and crushing combat to tell a self-contained, tragic story.
