The Vault-Tec warehouse is located deep within the city of Los, and consists of a main floor, a basement, and an entrance to the Secret Vault. This warehouse was heavily guarded by the Church of the Lost, a cult led by Blake, until an army of super mutants attacked and wiped out most of their forces. Since the super mutants in charge, and having entered the vault, the warehouse has become a battlefield between the remaining ghouls, the invading super mutants, and a horde of mutated radbugs that were attracted due to the activity and carnage. A Shop-Tec terminal can be discovered within this warehouse, along with turret robots that are guarding the entrance to the vault.
