What If the Brotherhood of Steel Allied With the Enclave Part 2

Following the collapse of the Iron Pact, President Serena merges her consciousness with the bio-mechanical "Unmaker" hive mind, forcing the NCR to launch a desperate offensive into the ruined east. The Republic utilizes the ancient ARCHIMEDES II orbital laser to halt the alien invasion before special forces infiltrate Serena's fortress at Cheyenne Mountain and incinerate her. Though victorious, the NCR transforms into a grim authoritarian garrison state to maintain control over the traumatized continent. The story concludes with a new existential threat looming as the warlord Ghor engineers a self-replicating "Super-Mutant Hive" to challenge humanity's dominance.
