Detailed walkthrough
To start the quest, you have to speak to Dr. Hildern in the Camp McCarran station. Dr. Hildern can be found in his office located inside the Camp McCarran Terminal building at the east side of the terminal in the south wing. After speaking to him, he will tell you that Vault 22 has data on its computers that will help him prevent a food shortage. He will give you the location to Vault 22 and ask you to enter and download the experimental data onto your Pip-Boy. Before leaving the base, make sure to speak to Dr. Williams so you get the optional objective to find Keely, a researcher who went to the vault before and has become missing. You find out from Dr. Williams that Dr. Hildern has sent other people on his task but none of them have returned.

The vault is easily found by following the map marker. There are quite a few Cazadors who roam the area. Just outside the vault entrance are 4 Giant Mantis hiding in the foliage. The door is permanently open and full of overgrown plants. Inside the Vault are numerous Manti and what are known as Spore carriers. In the Pest Control there are Spore plants who shoot toxic vomit much like the Centaurs are known for.

Once inside you have the choice to repair the elevator (with a skill check) or walk the five levels by stairs. There are Spore carriers hiding in most of the patches of plant growth. Whether you choose the elevator or the stairs you need to find the Overseer's office, which is located in the Common Area. Follow the arrow through the common area to the computer in the Overseer's office to unlock three doors. The third door will actually be a malfunction error of "Manual Override at Door". This means that unless you have 75 lockpick, you need to head for the Crew Quarters (now unlocked via the Overseer's computer). There is a key card in the first room on the left side of the hall as you enter the crew quarters. Be careful, there are two Spore Carriers waiting inside. With the key climb the stairs(you can not use the stairs because they are blocked) or take the elevator to Level 5, Pest Control. Follow the arrow to the door (if you picked up the key card it will just open, otherwise pick the lock).

You do not need the keycard to access the databanks. One of the first two doors that unlock from the overseer's office is the databank door.

Finding Keely is a bit more difficult. Keely turns out to be a Ghoul. She credits being a ghoul with saving her from the abominations, as the Mantis creatures captured her and were going to feed her to the Spore Plants but they were not interested in Ghoul flesh. On the pest control level she is found by leaving the vault through a hole in one of the labs and traveling through a short cave to a large open cavern filled with Giant Mantis and Spore Plant creatures. She is on the south end of the cavern sitting alone next to a Mantis pod.

Follow Keely to the second floor (Oxygen Level). Keely tells you about a plan to burn all the spores.
 * There is a duffel bag with frag grenades beside Keely in the room were you met up with her on level 2 (Oxygen level).
 * On the bottom level of the common area (where you found the overseers office)there is a room marked Utility, which contains a Flamer in the far corner along with plenty of fuel.

Keely tells you to find where two vents exhaust beside each other on the fifth floor, these are circular vents that are right next to the entrance of the room to the cavern on the Pest Control level. You need to light the gas that is leaked into the vault without killing yourself. This may be difficult to do as most places on the fifth floor are consumed by flames. It can however be safely done by throwing an explosive, like dynamite or a frag grenade out of the doorway into the hall from the room with the data. Once the explosive is thrown you must quickly close the door so as not to be caught in the explosion.

When you return to Keely to collect your reward, she'll talk about destroying the files from the computer. If you have the files she'll discover they were downloaded and you have multiple options from here:


 * Tell her the truth and destroy the codes for good karma. If she lives you will get caps or Karma depending on what you bartered with Dr. Williams.


 * Tell her the truth and refuse to destroy where she will become hostile. Killing gives you her password to leave. Make sure to use her computer to unlock the door. This gives you NCR infamy.


 * Tell her the truth and refuse to destroy it, and flee the area. Go back in and she should be non-hostile again. Pickpocket the password from her.


 * Lie and let her live. You will lose karma for lying but gain it for saving her.


 * With a Science skill of 70, you can keep the data while Keely Remains alive. She will unlock the door for you and you receive positive karma. You must choose the speech option of telling Keely that Dr. Hildern sent you for the data in order to get the Science speech option.


 * If you are on the companion quest with Veronica you will have another option to save the data without bloodshed.


 * If you tell her Dr. Hildern send you, you can say that your friend is part of a big organization that can use this data to help people. She will then state that you have given her no reason not to trust you and opens the door for you.


 * If you've already handed in the data with Dr. Hildern, Keely will tell you that the data should be deleted but will not confront you. This can result in a situation of being locked in the vault, to escape either pickpocket or kill Keely for her password, and use her terminal to open the locked door.

After that, whatever you chose you must return to Dr. Hildern.


 * If you saved the data he will give you 1200 caps and you can get an additional 600 with a high enough Barter(50) or Speech(50) skill.


 * If you deleted the data, the quest will end with you informing Dr. Williams that Keely is safe or dead. Dr. Hildern will suspect her responsible for the data being gone. No matter what response you choose afterwards, he will suspect you as an accomplice and demand that you leave the lab in anger.


 * If Keely died, you can tell Dr. Williams a lie with a speech check. You get 800 caps and lose Karma this way. If you don't, you won't get anything but you won't lose karma.

If you do not have the files downloaded she will tell you she has set it up where she can delete all the files from her computer.

With a speech skill of 50 you can tell her not to delete the files, which you can keep and still receive good karma (save for killing Keely) and your fame with the NCR will be raised.

Bugs

 * Keely might not turn hostile at all when you tell her you won't delete the data, but instead claim how you leave her no other choice, stand up, and sit back down at the computer. No further interactive dialog is available.


 * When attempting to access the door from the Oxygen Recycling level that is "Locked - Requires Key" the terminal to the left of the door that allows access with the keycard from the Crew Quarters may not be there at all! To fix this leave the Vault and re-enter. The terminal should come back.


 * It's possible to earn infinite experience points with 25 speech from Dr. Williams. After you get the quest from Dr. Hildern, you can ask Dr. Williams about how she feels about Dr. Hildern. If you pass the 25 speech check you'll earn 25 exp. 28 exp if you have the
 * If you complete this quest prior to beginning You Can Depend on Me it may be impossible to give the invoice to Dr. Hildern to progress in the quest.


 * Veronica, Boone and Rex turn up by the elevator every time after using it, even though they had been told to wait.


 * when detonating the gas you dont need to close the door to the secure room the fire doesnt enter even though its wide open.


 * X-box: When detonating the gas, should you die doing it, the X-box may freeze at the point of death/explosion -- note that this does not happen every time.

Note

 * The title of the quest is a nod to a 1950s country song 'There Stands the Glass', sung by Webb Pierce.


 * If given the chance to get close to you for a couple of seconds, the Spore carriers will explode and release large amounts of radiation.
