In the southwest is the Entrance to the Vermin Catacombes, where you find some Cockroaches, Black Ant's and the "Subject GX324".
The CoGs have managed to enter the old Missile Silo and plan to set off the nuclear warheads within. The Shiva's Favored wait outside the structure hoping to witness the destruction of the human race. A small group of Enforcers hope to combat the CoGs and remain in the northeast section of the area while a few other people remain inside hoping for aid.
