Vault 34 stands out as one of the most hazardous yet rewarding subterranean facilities in Fallout New Vegas. Located east of the Vegas Strip near Camp Golf, this subterranean complex is notorious for heavy radiation and relentless feral ghouls. Navigating its submerged corridors requires careful preparation and precise objective management to claim rare weapons and finish key quests.

Finding the Entrance and Essential Preparation

Before traveling east towards the vault, players should stockpile RadAway and Rad-X to withstand intense ambient radiation. Equipping a Rebreather is highly recommended because several flooded stairwells require prolonged underwater exploration. Utilizing high-caliber weaponry or rad-resistant armor will keep combat manageable against incoming ghoul hordes.

Draining Submerged Halls and Locating Passwords

Exploring the initial levels reveals flooded corridors that block progression toward deeper security sectors. Players must locate submerged vault technicians in flooded lower sections to retrieve vital access passwords. Using these credentials at the main security terminal drains the water and unlocks access to the Overseer's sanctuary.

Defeating the Overseer and Securing the Armory

Breaching the Overseer's office triggers a challenging battle against the ghoulish leader and guarding security turrets. Once defeated, looting the terminal password allows players to disengage the lock securing the main armory door. Returning through the clinic section grants entrance into the heavily stocked weapons cache. Inside, players can retrieve powerful unique gear including the All-American marksman rifle and the Pulse Gun.

Resolving the Hard Luck Blues Quest Moral Dilemma

Reaching the reactor core presents a pivotal moral decision regarding the fate of the remaining vault survivors and NCR agricultural efforts. Players can choose to seal the reactor leak to protect the NCR Sharecropper Farms' water supply, which dooms the trapped dwellers. Alternatively, venting the radiation saves the surviving vault inhabitants, allowing them to relocate safely to the Aerotech Office Park.
