How Do I Get to Vault 112?

Vault 112 is located underneath Smith Casey’s Garage. The Garage is in the Southwest quadrant of the map, near Girdershade and Evergreen Mills. You’ll need to go downstairs into the basement, and you’ll find the entrance to the Vault.

Read part of the walkthrough for more detailed instructions on how to find Vault 112.

How Do I Get Out of Tranquility Lane?

You can’t! You’re stuck forever! Muahahaha!

Just kidding. Betty controls the town, and you’ll have to convince her to let you out. The simple way to do this is to do exactly what Betty asks you to do. Old Lady Dithers will give you an alternative suggestion, and if you figure out the puzzle you can force Betty to allow you to leave.

Ultimately, Betty will open a door for you to walk through – taking you back to the real world of the Capital Wasteland.

Where Did All my Stuff Go?!?

It’s only gone temporarily. While you’re inside the Tranquility Lane simulation, you won’t have access to any of your inventory items – or to your Pipboy. Try to bring up the Pipboy and you’ll just see a silly wrist-watch.

As soon as you escape Tranquility Lane, all of your inventory items will be restored to you. However, you’ll have to re-equip your armor and reset the hot keys for your weapons.

Where’s My Dad, James?

He’s hidden in the simulation. Betty, Dr. Braun, turned him the dog Doc that hangs out on the playground. This confused me the first time through, because I thought the dog was Dogmeat!

Betty will eventually tell you that he tried to make James play the same games, but James refused. When you convince Dr. Braun to let you leave, he’ll also tell you that your father is the dog and that he’s free to go, too.

Do I Have to Be Evil in Vault 112?

Nope. There are two clear routes to escape Vault 112.

If you listen to Old Lady Dithers and figure out how to use the failsafe terminal, you’ll gain Karma points and Dr. Braun will be forced to let you James leave Tranquility Lane. You can read the relevant section of the walkthrough to learn how to use the failsafe terminal.

If you choose to play along with Betty, you’ll lose a lot of karma. You’ll eventually have to kill everyone (except for Timmy) and you’ll complete four quests that reward you with negative karma.

How do I Access the Failsafe Terminal that Old Lady Dithers Keeps Babbling About?

Go inside the abandoned house. Use the objects in the house in the following order: Radio, Pitcher, Garden Gnome, Pitcher, Cinderblock, Garden Gnome, Bottle.

If you completed the pattern correctly, the failsafe terminal will appear.

For a more detailed answer, read the relevant portion of the walkthrough on how to use the failsafe terminal.

How Can I Kill Mabel Henderson With Her Oven?

There are four different ways for you to kill Mabel Henderson. If you fiddle with the things in her house, it will seem pretty obvious that using the oven is one of them.

When you use the oven, you’ll have an option to tamper with the pilot light. I originally thought that if I left the house and waited, it would explode and kill Mabel Henderson. No such luck.

After tampering with the pilot light, you need to go talk with her and ask her to bake you a pie. You can then follow her downstairs and watch her die in a puff of flame.

Read the relevant section of the walkthrough for the other ways to kill Mabel Henderson.

Why Do I Gain Karma from Killing Everyone?

If you use the failsafe terminal, you’ll be able to activate the Chinese Invasion program. The flavor text in the failsafe manual explains that this will kill the residents of Vault 112 in real life, not just in the simulation.

It may seem a bit counter-intuitive to gain karma from slaughtering everyone, but the designers have decided that this is the humane thing to do to them. By killing them in real life, Braun can’t continue to resurrect them in new simulations and torture them. It also leaves Braun alone for eternity because he has no way to leave the simulation or kill himself.

Just one of those strange karmic decisions of Fallout 3.

Personally, I’d have preferred an option whereby I could leave the simulation (by following Betty’s orders) and then murder Braun in his Tranquility Lounger – leaving the residents of Vault 112 to control their own simulation. But unfortunately, that is not an option.

Back to the list of FAQs.

Do My Karmic Choices in Tranquility Lane Effect Later Parts of the Game?

Nope. Even though your father refused to play along with Braun and torture the residents of Vault 112, he apparently doesn’t care what you do.

When I completed Tranquility Lane the Evil way, I expected him to have some dialog about my decisions. No such luck. It seems that Tranquility Lane and your decisions there are entirely self contained – except for possibly changing your karma level.

This is one of the persistent problems in Fallout 3, IMO. Your karmic decisions have very little impact on the development of the story line. At the very least, it would be nice if there was some dialogue to resolve the fact that your father has just found out that you’re a world reknowned mass murderer.
