Vault 22 Common Area
Vault 22 exterior.
Vault 22 is a Vault-Tec Industries Vault in the Mojave Wasteland, home to a variety of plantlife and wild animals, most notably giant mantises. Humans, the intended occupants, are nowhere to be seen. The Vault is located south-south-west of the Griffin Wares sacked caravan and directly west of The Thorn.
Designed as a green Vault, people selected for populating the Vault were all dedicated to one goal: Sustaining the Vault population with plants grown within its confines. Some of their most successful experiments were, in fact, donated by defense contractors, such as the fungus that would eventually become the Vault's undoing.
Beauveria Mordicana was originally an entomopathogenic fungus designed for pest control. When a pest is exposed to the fungal spores, the fungus infests it and begins to colonize the host body. The host eventually dies due to failure of body functions, as the colony expands through its body. However, the dead body continues to be controlled by the fungal colony, allowing it to move around and infect more pests by spraying spores around the host body. While effective in the long term, it still takes between 10 to 20 days to kill its prey and achieves limited effectiveness when dealing with unsocial pests. The fungus was originally developed at the X-22 botanical garden at the Big MT, though the technology was eventually shared with Vault-Tec Industries, to enable botanical experiments at Vault 22.
As with many technologies coming out of the Big MT, the fungus was a Pandora's box. Once the Vault scientists began experimentation with the fungus after the Great War, they effectively signed their death warrant. While ostensibly designed to provide effective means of long-term pest control, the fungus was perfectly capable of infecting human bodies. Fungal spores gradually spread through the Vault, slowly infecting the population. The first confirmed infection was Dr. Harrison Peters, who also provided insight into the development of the infection. It begins with pneumonia as the fungus invades the lungs, eventually transforming into chills, a fever, and a terrible racking cough. The fungal colony causes the body to actively reject anti-fungal treatments, leading to death due to organ failure. As with smaller pests, the fungal colony continues to grow and develop. Eventually, it spreads far enough to establish control over the deceased person's body, becoming a highly aggressive spore carrier, a mindless beast whose sole purpose is spreading the spores. The untreatable infection baffled the scientists and spread through the Vault like wildfire.
The widespread infection led to a collapse of social order in the Vault. Infected humans were turned into spore carriers, with the airborne fungal spores threatening the remaining living. Scientists attempted to eradicate them by igniting gas deliberately released in the lower levels of the Vault. However, the release triggered an incredibly aggressive reaction from the carriers, which attacked the scientists, tearing them limb from limb.
By 2096, the Vault was finally was abandoned and a party of 118 survivors made way for the Zion Canyon. The dead eventually mutated into spore carriers or became stationary colonies of the fungus. The dwellers were savages. They traveled to the Zion Canyon. With over one hundred men and women, strong discipline, tactics, and firepower, the small band of Mexican survivors camped out there posed no threat to the dwellers. They hit the survivors' camp on February 11th, 2096, killing all the men and shooting down women and children that resisted. The remainder was taken to the main camp of the dwellers and penned in like livestock.
Randall Clark, the guardian of the valley, was desperate to help the Mexican survivors. Over the next two days, he surveyed the area. Vault 22 dwellers were organized well, with patrols and sentries set up along all approaches into the camp, except for the stream. The coughing among the dwellers puzzled Clark, but he ignored it as he prepared to save the surviving Mexicans. He went into the camp on February 14th. What he saw snapped something inside him. The Vault 22 dwellers killed and ate everyone they took from the Mexican survivors' camp. Clark retaliated, waging a brutal war of attrition against them. With his rifle in hand and all the explosives he could use, he ambushed the dwellers where he could and booby trapped bodies and weapons he could not take. By the end of February, he killed 24 dwellers in a cold, merciless campaign of vengeance. In the ten days it took to accomplish this, he only suffered one wound: a 10mm steel jacket round through the thigh, thankfully missing the femoral. Though he remained unseen by survivors, he was forced to move camp when on March 2nd, a small patrol nearly uncovered his camp in the cave when one of their men was caught in a deadfall trap. Panic fire almost hit him. After he disposed of the intruders, he moved camp to Cueva Guarache. Victory came ten months later. After losing six concurrent Overseers and more than eighty members of the group to Clark and sickness, the dwellers gave up and fled the canyon, after eating their dead for nourishment. History loses track of them past that point, maybe for the better. Occasionally, damaged PIP-Boys and jumpsuits from the vault would find their way into the hands of prospectors.
The Vault itself fell into disrepair over the years, overrun by the plants and wildlife that thrived in the conditions within. The occasional scavenger quickly fell prey to the creatures dwelling within or the fungus, if they managed to survive. It wasn't until roughly 2281, when it piqued the interest of others. More specifically, Thomas Hildern, Director of OSI East. He has hired multiple mercenaries to retrieve the secret of the Vault, hoping to find a way to enhance the agricultural output of the NCR and stave off projected famine. Of course, the biggest benefit would be a major promotion for him. His latest hire, Keely, has gone missing much like the previous mercenaries, but this time, the situation is different...

The entrance of this vault is quite unusual. It is advertised with a sign that reads "Welcome to Vault 22" covered by "stay out! The plants kill!". The vault door leads directly outside, unlike most that have a natural rock formation or tunnel enclosing the entrance.
Once inside the Vault, the Courier will come to a door that leads to a room with an elevator and stairs. From here on out, the player will encounter spore carriers, spore plants, and giant mantises throughout the Vault. The vault is split into five levels, the different floors can be accessed by repairing the main elevator within the Vault (requires repair skill of 50) or accessed by perpendicular staircases.
 1st floor - Main Entrance
Immediately upon entering the vault, turn to the left to find a usable mattress, a duffle bag with some supplies, and one of Keely's terminals with entries 1 and 2. Next to the mattress hidden between two books is a Programmer's Digest.
 2nd floor - Oxygen Recycling
From the entrance of the lab take a right and continue to the room directly across the hall to find one of Keely's terminals with entries 3, 4, and 5 in the series.
 3rd floor - Food Production
The key card to access the tunnels is located in the Common Quarters (the floor below). Once inside, an average locked door must be opened on the lower level in the northwestern corner of the room. Once inside, the first room on the left, on a shelving unit will have the 'Vault 22 Cave Door Keycard'.
From the elevator, go down to the hallway and into the first room on the right to find one of Keely's terminals with entries 6 and 7 in the series.
 4th floor - Common Areas
From the entrance to the Commons, take a right over the little bridge and straight back to the billiard room for one of Keely's terminals with entries 8 and 9 in the series. The keycard that unlocks the door to the tunnels on the Food production level is found in the lower level of the Common Areas in the Quarters section on a shelf in the first room to the left. If the keycard cannot be found, check the floor near the shelf as it may have somehow fallen off. It is a darkish red/orange color.
 5th floor - Pest Control
This floor is filled with deadly "Savage" spore carriers. The large cavern contains many giant mantises and spore plants. Five mantis ootheca and Keely are located here.
 Original inhabitants
 Notable loot
- AER14 prototype - on the fifth floor; Pest Control, enter the stairway door to the Common Areas directly to your right which has a very easy lock. The AER14 is laying on the ground next to a scorched skeleton with some energy cells.
- Flamer - located in a room labeled "Utility Room" in the lower southern part of the 4th Floor Common Areas. A large supply of fuel is located in the same room.
- Laser pistol - on a table to your left as you enter the room with the flamer and decent amount of ammunition.
- Programmer's Digest Next to a mattress, under a book in the little camp set up at the Vault entrance.
- Tales of a Junktown Jerky Vendor - located on the 5th level "Vault 22 - Pest Control". If you take elevator to "Pest Control", then turn left and go up the stair to a large room with the door that leads to the caves Food Production, turn left and it is on the long table with bubbling vials or on floor in front of the long table.
- Frag grenades can be found in the second floor room where Keely briefs you on the plan to destroy the spores.
- Cave fungus on the floor in the bar on the 4th floor (Common Areas level).
- 6 HEPA 20 cartridge filters, used for Still in the Dark, located in a blocked-off section of 2nd level "Oxygen Recycling" which can only be accessed via the cave system surrounding the vault (the room and its cave entrance are visible through a window on the main part of the 2nd level). There are entrances to these caves on the 5th level "Pest Control", and on the 3rd level "Food Production", the terminal here will not open the door to the caves without the Cave Access keycard, which is found on 4th level "Common Area", downstairs on a shelf in the bedroom with the baby carriage. Once inside the destination room, the last locker on the left contains the HEPA filters.
- A Food additive meant for Cpl. William Farber in Camp McCarran. When exiting the elevator on the 3rd Floor-Food Production level, make your way down the main hallway and enter the last hallway on the left before the main hallway turns right. Enter the first room on the left and walk to the back where there is a small office-like room with spores growing in front of the desk. The food additive is sitting on the top of the desk, but can be knocked over into the corner by a spore carrier.
- Numerous Vault 22 jumpsuits - are located on 4th floor-common area.
 Related quests
- The vault door is slightly open and the entrance room is visible through the gap.
- The spores don't seem to be contagious at all, even though in There Stands the Grass Keely tasks the player with destroying the spores in the air by igniting gas in the air that both the player and Keely have been breathing.
- This is one of the two vaults in the Mojave Wasteland without an entry tunnel, the other being Vault 3. Furthermore, 22 is the only vault in the Mojave wasteland whose vault door would have opened directly to the outside world at the time of its construction, similar to many of the west coast vaults.
- If you have found and spoken to Keely, she remotely locks the entrance to Vault 22. You can get her to unlock it only after completing her quest. Alternatively, you can pickpocket her for her terminal password and use it to access her terminal on level 2 (where you met up after finding her in the caves) and unlock the door yourself.
- There is a hollowed-out rock directly across from the sign at the entrance.
- The rubble on the Fourth Floor blocking the stairs down near the elevator has gaps near the top, a grenade or incinerator through the cracks can kill the mantises at the bottom, which will keep followers from wandering around that hallway.
- The Vault dwellers are responsible for bringing spore plants and spore carriers to the Zion area.
- When examining the vault door closely, the door number actually reads Vault 92 instead of 22.
 Behind the scenes
Vault 22 was designed by Jesse Farrell.
- The key card from quarters (needed to enter the cave) can, on rare occasions, never appear and cannot be found.
- With the PS3 system update 3.60, the "trigger" event to download the data from the terminal on Level 5 doesn't happen, preventing continuation of the storyline.
- Take caution if you are to take ED-E on to the fifth floor and trigger the flames. Make sure ED-E is in a room where it is protected from the flames as it can be "killed" even if you are not in Hardcore mode and never register as being dead (in fact you will still see a marker indicating that he is at Vault 22) thus robbing you of having a second follower for the rest of the game. If you don't want to have to worry about this, just have him wait at the entrance or at your Lucky 38 suite.
- When inside the Vault, the door has another texture problem. You can still see the 92 but it also shows a 101 and an overwrite sign from the doors (you need to use the console to see this).
- Many times while in Vault 22 your companions will sense enemies nearby, when in fact they are on another level of the Vault. This makes them run off to the corners of rooms, stairwells, etc. in search of their foe(s).
- HEPA 20 cartridge filters and talking to Keely she will not appear in her lab and the door to exit the Vault will need a key to unlock with the key and Keely will be impossible to find. Exiting the game and restarting from that point seems to fix this problem. If entering the Vault for the
- Sometimes, the giant mantises outside the Vault do not spawn. They are likely to spawn when you exit, though, so be prepared for five or so mantises on top of you if this happens.
- Leaving companions outside of Vault 22 and then entering the Vault will cause a glitch where your companions disappear. They are noted on your world map as being at Vault 22, but they are not there.
- There Stands the Grass before unlocking the door that leads to where Keely is and then rescue her, she will still attempt to have you do her portion of the quest which includes her locking the front door. Since you've already dealt with the data, you cannot do anything else for her after activating the gas on the 5th floor and remain locked in. (Killing Keely on the second floor, after being asked to activate gas, should generate a network key on her corpse for the computer. Click on terminal and unlock doors.) If you complete the Quest
- ED-E appears upon entering level five via the elevator even though he is told to wait elsewhere, even if told to wait outside outside of Vault 22.
Vault 22 appears only in Fallout: New Vegas.
- Fallout: New Vegas Official Game Guide: "Vault 22 was a "green" vault, filled with scientists dedicated to their experiment: keeping the entire population of the vault alive with plants grown with its confines. The experiment could be said to have exceeded all expectations, but with horrific side-effects. Many have attempted to locate the data the scientists left behind, but so far nobody has returned alive. The vault is open, but warning signs surround it from people lucky enough to survive their initial encounter with the vault's inhabitable. Don't forget to check the Hollowed-Out Rock on the right side of the gully, across from the "Keep Out!" sign."
- Vault 22 terminal entries: "Species 3
Species: Beauveria Mordicana
An entomopathogenic fungus, B. Mordicana has been developed to colonize the bodies of most common pests. Once it has fully colonized a host body, the host technically dies, but the body continues to move by means of the fungal colony within it. In this manner the fungus moves amongst more of its prey, occasionally spraying spores in a radius around the host body, infecting all who come near it. Its drawbacks include the time it takes to kill prey (10-20 days) and its limited effectiveness when dealing with unsocial pests."
- Old World Blues endings: "The Biological Research Station, obsessed with seeding everything in sight, requested a transfer to the X-22 Botanical Garden... so that it might, in its own words, "sensually fertilize the garden's smooooth contours." The Garden sent back a polite refusal, saying it had prior commitments with a Vault it had helped infect before the war."
- Patient Zero
- Vault 22 terminal entries: "Case 162: Patient: Peters, Harrison T.
Condition: Dr. Peters is suffering from a severe case of pneumonia, the result of the spread of some sort of microorganism in his lungs. I've applied the usual treatment and requested that he refrain from working and stop by twice a day for observation."
- Vault 22 terminal entries: "Case 164 (Group)
Patients: Mitchell, Pam; Cordella, Michael; Norton, Samwise; Fujimoto, Naoki; Derrida, Kenneth
Update: This entire group showed up throughout the course of the day displaying the same symptoms. They're remarkably similar to Dr. Peters' condition when he first came in a week ago. I hope we don't have a contagion on our hands."
- Vault 22 terminal entries: "Case 162 update: Patient: Peters, Harrison T.
Update: Dr. Peters isn't responding to the treatment, or, more accurately, his body is actively rejecting the treatment. His condition has worsened and I'm on the cusp of ordering exploratory surgery."
- Vault 22 terminal entries: "Case 173 (Group): Patients: Bailey, Elizabeth; Bailey, Marsha; Garfield, Hayes; Amy, Herman; Jenkins, Veronica; Keyes, James; Kilpatrick, Robert; Lowry, Amanda; Orlando, Donald; Pamino, Iris; Rado, Steven; Reyes, Yolonda; Sarkin, Kelly; Valdez, Nicholas
Update: Another group with chills, a fever, and a terrible racking cough. I'm recommending that they be separated from the general populace."
- Vault 22 terminal entries: "Case 162 update: Patient: Peters, Harrison T.
Update: Dr. Peters is dead. His vitals flatlined ten minutes before he entered surgery. I decided to perform an autopsy immediately, and discovered his lungs were filled with some sort of fungal infection. Strangely, the fungus still shows evidence of growth despite the death of its host. I'll consult with one of the mycologists on the fifth level and see if they can identify it."
- Vault 22 terminal entries: "Case 162 update: Patient: Peters, Harrison T.
Update: I don't really know how to describe what just happened. One minute I was closing up for the day and the next Dr. Peters' corpse sat up and attacked me. I was able to flee the office and seal him (it?) inside until security arrived, but what the hell is going on? If all the recent illnesses are the same thing..."
- The Courier: "How did you get this whole gas thing set up so quickly?"
Keely: "That's a very good question! Actually, I didn't come up with it. The systems were already set up to pump the gas when I first arrived here. I believe the scientists were in the process of attempting to ignite the gas just as we're about to do. And by we, I mean you, of course."
- The Courier: "What happened to the scientists, then?"
Keely: "Something prevented them from igniting the gas, obviously. I suppose it's possible that the gas triggered some kind of defensive reaction. Hordes of previously slumbering creatures may have awoken and entered a killing frenzy, ripping the hapless scientists into quivering, bloody chunks. You'll have to let me know when you get back from going downstairs."
- Vault 22 terminal entries: "Vault 22 Expedition, entry 6: I've finally found some of the bodies of the scientists that lived here. They appear to be overgrown with some form of lichen. They blend in so well with the other growth that I walked right by several of them without even noticing them. I've taken the proper precautions, but the lichen doesn't seem to be contagious, at least to ghouls."
- Vault 22 terminal entries: "Vault 22 Expedition, entry 8: I guess no one will miss this ridiculous trivia game. The questions weren't even that hard.
It looks like this is where most of the people were when they died. The medical reports I found suggested that most of them succumbed to some kind of airborne infection. I'm going to see if I can convert some of the growlamps into UV spectrometers to test the air for contaminants."
- Vault 22 terminal entries: "Vault 22 Expedition, entry 9: After numerous attempts, I've found a range that highlights the particles in the air that I believe killed everyone in this vault. Preliminary tests show them to be spores of some kind. I've set up spectrometers on several of the levels now and the concentration appears to increase in the lower levels. At this point, I'm concerned that the plants here may constitute a danger to the people of the NCR."
- 2096 terminal entry: "Year 2096 I.
Fuckers killed all the men. I think they would've taken the women alive but Maria and Selena opened fire and some of the others went for their guns so they shot them down and some of the kids with them.
If I could've warned them.
Elena and Carmen and 5 children still alive, being kept in a pen.
There are more than 100 of these assholes in blue suits. Every suit says "22" on the back. Why? Armed to the teeth with submachine guns, pistols. Estimate 60% male. Everyone seems to follow the dark-haired guy but can't get close enough to tell. Assholes are disciplined - patrols, sentries - they mean business.
Say I go in at night and get the women and children out. Where to next?
But I have to get them out. Have to.
Recon during night.
Well-organized, sentries along most approaches, but stream not covered.
Are they sick? Lots of coughing fits. Tuberculosis?
Women and children still in pen. Will try to infiltrate by stream tomorrow night.
They ate them.
Ambush along riverside trail. 6 males killed. Heard their coughing a mile away.
Used their grenades to booby-trap bodies, kept half. Secured 6 SMGs, 500 rounds 10mm, 6 frags.
Ambush along riverside trail. 2 males died checking bodies. Killed 2 more with rifle. Shot 1 through calf and let asshole crawl off to spread message. Coughed like I'd shot him through lungs.
Ambush half-mile east of coal pits wash. 8 males killed."
- 2096 terminal entry: "Year 2096 II.
Ambush in the narrows. 6 males killed. Took a 10mm through thigh, steel jacket, missed femoral. Lucky. Used tourniquet to make sure no blood spattered on rocks back to cave. Have set traps all along entrance passage but if they find me it will be matter of time. Still, 24 confirmed kills in 10 days = at least 1/3rd of their combat force, not bad for an old man.
Lucky lucky lucky lucky. Patrol was small - 3 men. Screaming woke me - point man caught under deadfall. Panic fire ricocheted into the cave, almost hit me. Crawled forward and killed them all with SMGs. Nearly used frags, stupid, finger in pin when remembered ricochets.
Leaving at once. No other patrols in area but they'll be searching narrows for these 3. Taking as much food as I can drag with me and heading to cave south."
- BEWARE - A VENGEFUL SPIRIT STALKS THESE CANYONS: "If you are reading this message do yourself a favor and turn and run straight out of this canyon.
For near 11 months my people have been engaged in daily battle with an evil spirit of this place.
Arriving February of last year with a party 118 strong, we were attacked by primitives and forced to defend ourselves. Whereupon something began killing us in wide numbers. We have done our absolute best to find and kill this thing, thinking it was a man because it uses our firearms against us and traps of all kinds. But no man could defy our efforts as this thing has. It is more evil than any man could be.
We have been reduced to just 34 of our number. We have lost six overseers before me. Some have perished from the sickness in their lungs we carried out of the Vault. But that number is small next to the count of friends this thing has murdered.
Now that I am finally made overseer, we are leaving straight away and will not return. If you have come to this seeming paradise seeking the fresh water, abundant game, and shelter you suppose you will find here, do not be deceived. You will find only death here. Leave at once and put miles between you and this place.
May God have mercy on us all,
- The Courier: "Where'd you get the Vault suit?"
Ricky: "Where the fuck you think? Vault two-two! That's where I grew up!"
The Courier: "You're lying. I've been to Vault 22. No one's lived there in 150 years."
Ricky: "You been to Vault two-two, huh? I may have been exaggerating a little. Truth is, I got this suit and the Pit-Boy off a dead prospector who came out from Zion. Guy was dead when I found him, okay? Had a ton of shit on him. That's how I know there's good loot in Zion, see?"
