Vault 22 Fallout New Vegas Location And Quest Guide

Navigating the overgrown ruins of Vault 22 is one of the most memorable yet treacherous experiences in Fallout: New Vegas. Known for its lush greenery, dangerous flora, and claustrophobic hallways, this subterranean facility hides valuable research alongside deadly mutated threats. Understanding how to find this vault and complete its associated quests efficiently will save players time and resources during their wasteland adventures.
Locating Vault 22 in the Mojave Wasteland
Vault 22 is situated in the western part of the map, located west-northwest of Westside and directly south of the Followers safehouse. As players approach the entrance, they should remain cautious of dangerous wildlife patrolling the surrounding area, such as deadly cazadores. The entrance itself is marked by dense vegetation, signaling the unique environmental hazards hidden inside the facility.
Key Quests and Objectives Inside Vault 22
The primary quest tied to this location is There Stands the Grass, given by Dr. Thomas Hildern at Camp McCarran. Players are tasked with retrieving agricultural research data that could potentially help solve food shortages across the region. Additionally, the Brotherhood of Steel quest Still in the Dark requires players to locate essential HEPA 20 cartridge filters on the lower levels of the vault.
Navigating the Vault Layout and Accessing Hidden Areas
Exploring Vault 22 can be confusing due to broken elevators, blocked passageways, and complex cave systems connecting the levels. Players will need to find the Vault 22 cave door keycard in the living quarters to unlock specific terminal-controlled doors. Repairing the central elevator simplifies movement between floors, making it much easier to reach deep maintenance zones and complete objectives safely.
Surviving Threats and Completing Quest Choices
Inside the facility, players will face aggressive spore plants and camouflaged spore carriers that lurk within the foliage. During the research retrieval quest, players encounter Keely, a ghoul scientist who warns about the dangerous nature of the vault's data. The Courier must decide whether to erase the research to prevent future catastrophes or deliver it to Dr. Hildern for a lucrative cap payout.
