Tranquility Lane is a Fallout 3 quest, an Xbox 360/PC achievement and a PlayStation 3 Trophy. The quest begins immediately after the completion of Scientific Pursuits, which ends when the player sits in a Tranquility Lounger in Vault 112 and begins the simulation that comprises Tranquility Lane.



Tranquility Lane is a virtual reality simulation housed in Vault 112. The player is tasked by one of the residents, Betty, with an ever-escalating series of violent jobs in order to free their father James from the simulation. As an alternative to completing the violent tasks, the player may free their father by activating the "Fail Safe" solution, which gives good karma instead of bad.

Betty's Tasks Solution

Betty will ask you to do the following things for her entertainment:

1.Make Timmy Cry:

  • Timmy can be quite easily made to cry by punching him or hitting him with the Rolling Pin.
  • For a more creative solution, you can convince him that his parents are divorcing each other because of him, or you can give him the Military School Pamphlet to fool him into believing his parents are sending him away.
  • To really impress Betty, kill one or both of Timmy's parents, and Timmy will run over to their bodies and begin to cry (You can also tell him before he has a chance to see it).

2.Break Up The Rockwells' Marriage:

  • The easiest method is to simply tell Mrs. Rockwell that her husband is cheating on her, which she will readily believe after a speech check.
  • You can also place the Lacy Underwear from the Simpson household on the desk in the basement, then tell Mrs. Rockwell that her husband is either cheating or he is a cross-dresser.
  • Finally, one can read Mrs. Rockwell's diary upstairs, which will indicate that she'd like to kill Mrs. Simpson. Take the Rolling Pin from kitchen in the Rockwell house and beat Mrs. Simpson to death with it, then tell Mr. Rockwell about it.

3.Kill Mrs. Henderson: Note that Betty is adamant that you cannot simply beat Mrs. Henderson to death, as that's boring; you must be creative about it.

  • The Henderson household has at least 4 simple ways to end her life:
  • The chandelier above the hallway to the kitchen can be rigged to drop when someone walks under it.
  • A roller skate can be moved to the stairs, resulting in Mrs. Henderson falling to her death when she tries to go upstairs.
  • Her oven can be sabotaged to leak natural gas. Ask her to make you a pie; when she lights the stove the explosion will kill her instantly.
  • Most elaborately, the security console in the kitchen can be accessed, allowing one to enable Security Lockdown, locking Mrs. Henderson in the house. Set robot to "Begin Security Program" Mode, and as it wanders around disable the "security parameters" data, rendering it unable to determine friend from foe. This requires that you make sure the robot does not see you or it will attack and can quickly kill you as well. If you do manage to destroy the robot after it kills Mabel but before deactivating its security mode, you will not be locked in the house, just deactivate the security on the terminal and you can leave.
  • Note: If Mrs. Henderson is not in her house, she might be in the Simpson house.

4.Kill Everyone: This is exceedingly simple: as Betty says, you'll find the Pint-Sized Slasher Gear in the doghouse to the right of the Abandoned House, which will automatically be equipped and cannot be removed. At this point, everyone will become hostile and attempt to flee from you (with the exceptions of Betty and Doc [The dog]); it can take some time to locate all the residents, as they'll often move from house to house to escape you. The markers on your compass can help you find them.

After everyone is murdered, Braun thanks you for the entertainment and tells you what you wanted to know most: Doc is actually your father, and has been watching you in horror the entire time. He then opens the Exit Door, allowing you to leave the simulation.

Alternative "Fail Safe" Solution

Failsafe Terminal
Failsafe Terminal in color

The player can, in fact, skip all of Betty's negative karma inducing tasks by simply finding the abandoned house at the beginning of the simulation. Just go around in the row of houses until you see one titled "Abandoned House". Step inside and activate the fail safe using the tones. You can also look at all the other notes written by Braun in here. After activating the fail safe, all the residents will be killed for good. You will receive positive karma, though, because you freed them from their otherwise eternal suffering at Braun's hands. Braun, as Betty, will be kept alive and forced to reside alone, forever. However, you can do all of the tasks for Betty and then activate the failsafe. You will gain good karma and the citizens of Tranquility Lane will be revived and killed by the Chinese soldiers (360 and PC. Confirmed on PS3).



  1. If the player speaks to Old Lady Dithers, she will tell the player that she knows that Tranquility Lane is a simulation, that Betty is really "Braun", and that he uses a "Fail Safe Terminal". She mentions that the player should go to the Abandoned House, but is quite obviously insane and mostly babbles.
  2. Within the abandoned house, the player will find a set of unusual objects which make unusual noises when activated. If the player enters the proper sequence, the Fail-Safe Terminal will reveal itself. In the terminal, selecting "Chinese Invasion" will summon a number of Chinese soldiers who proceed to murder the residents of Tranquility Lane, with the exception of James the dog, Betty, and the player. According to the notes on the Invasion program, this program disables the fail-safes on most of the pods, meaning that dying in the simulation will kill the real-world person as well.
    • If you can't remember the sequence to activate the terminal, note that each object has a specific tone, and Betty whistles the correct tonal sequence while playing in the center of the lane. Radio, Pitcher, Gnome, Pitcher, Cinder Block, Gnome, Bottle.
      • A helpful memonic for remembering this might be "Rads Please Ghouls, Players Can Glow Badly", "Run Pete! Ghouls Pay Carnage By Gnawing Bone" or "Ravaging People Gives Pretty Cash, Can Go Bad"
      • The background music for Tranquility Lane also incorporates the melody.
        • Another solution is to listen to the error sound that plays if an incorrect (out of sequence) note is played. It takes 5 tries to find the first tone, 5 for the second, 5 for the third and so on, so in a maximum of 35 attempts the puzzle is solved.
        • Players can also Quick Save between every correct tone to make things much easier.
      • Speaking to Braun, he will lament that he is now alone and trapped forever within the simulation, something confirmed by his own notes on the Chinese Invasion Plan on the Fail-Safe Terminal: the systems in place for his own safety will not allow him to be killed, even if the Invasion program is launched. He will further point out that Doc the dog is actually James, and he will be waiting for you once you leave the simulation.
      • Using the Exit Door on the playground will end the simulation.

Outside Tranquility Lane

As soon as the Tranquility Lounger pod opens, James will run up to the player and begin a conversation. He had intended to find some holodisks, memos, or even experiments from Braun related to G.E.C.K, but what he finds is a perfectly alive and insane Braun and got himself duped into Tranquility Lane as a dog. After some dialogue, he says he'll be returning to Rivet City to meet with Dr. Li and resume the project; the player can either immediately go with him or indicate that they've other tasks to attend to. This has no real influence on the plot, and James will leave for Rivet City regardless.

Important: Any companions who were with you (potentially Clover, Charon, or Jericho) will have been set to "wait here" mode, and must be told to follow or they'll remain in Vault 112 indefinitely. Dogmeat may be sent back to Vault 101. Certain NPC Follower characters may also have returned to their place of initial recruitment (such as Sergeant RL-3 who can be found waiting outside of the RobCo facility upon completion of this Quest). The player may also note that all of their weapon hotkeys have been disabled. This may be due to a bug, or because the player did not have any weapons during the length of the quest. before you leave, make sure to reset all of your weapon hotkeys.

This immediately concludes Tranquility Lane and begins The Waters of Life.


Depending on your character, you may not want karma to have an undesired effect on your game. Here is how to resolve Tranquility Lane based on your desired Karma:

  • For positive Karma: Do not play any of Betty's games; instead activate the fail-safe. This will grant you a positive Karma bonus and allow you to exit.
  • For negative Karma: Complete all of Betty's tasks and finish by killing everyone as the Pint-Sized Slasher. Exit when Betty reveals the door.
  • For neutral Karma: Play all of Betty's games except for the last "Kill Everyone" task. After killing Mrs. Henderson and before asked to become the Pint-Sized Slasher, go into the Abandoned House, activate the fail-safe, and exit. This will balance both negative and positive karma effects from this quest.

Following James (Dad) After Saving Him From Tranquility Lane

You have the option to follow your father all the way to Rivet City after saving him. If you choose to follow him, consider the following notes:

  • If you leave Vault 112 with James, he will start running to Rivet City on foot and is aware of your presence. He will wait for you if you choose to travel with him. He makes a great companion in the Wastes as he is armed with a laser rifle or a .32 pistol, essential (but not invulnerable and can be hurt to the point of unconsciousness while fighting strong enemies, so take this into account if you're thinking about letting Dad kill a Yao Guai or Deathclaw by himself), and make sure all wildlife attacks himself rather than you. Another added bonus is that he doesn't get hostile--besides verbally scolding you--if you accidentally (or even purposefully) shoot him, but you can damage him and eventually knock him unconscious. If you still need to explore the Wastes, and have not maxed your levels yet, it is a fun way of doing it. While on foot, "Dad" will even patiently wait in the middle of nowhere for you if you take a side-trip to explore, and he appears on your Pip-Boy as a quest destination arrow so he will never be lost to you. As soon as you approach him again, he will begin running, allowing you to travel at your own pace. If you talk with him while exploring, be sure to end the conversation with "I have to go, Dad" rather than "I changed my mind. I'm not going to go with you right now". The latter response will cause "Dad" to start running non-stop and he will not wait for you or protect you.

Important: Fast travel will force him back to Rivet City quickly, so there is no need to worry about him getting stuck in the wastes.


  • It is possible to bypass having to speak with Dr. Li in Rivet City by simply entering Vault 112 and entering Tranquility Lane.
  • Characters with 75+ Science Skill can use a terminal to unlock a door in the room with the tranquility chairs. That room contains a laser rifle, an assault rifle, a bunch of ammo, some meds, and a password for the Overseer's Room upstairs. The Overseer's Room contains Braun's tranquility chair and a safe with some caps. Curiously, there does not appear to be any way to interact with Braun's pod and end the simulation without going into Tranquility Lane.
  • If you attempt to check your Pip-Boy while in the simulation, you will instead see a simple Vault Boy wristwatch permanently stuck at 2:55. As it is impossible to check your quests, your goals will periodically pop-up on the left side of the display. V.A.T.S. still works as intended.
  • A few of the Chinese soldiers in the simulation can be heard yelling "For Chairman Cheng!".
  • Even though the Chinese soldiers do not normally attack Doc, if you attack the dog, the soldiers will immediately shoot at him until he is unconscious.
  • Although interaction with the Chinese soldiers is minimal, it is possible to pickpocket them whilst they are attacking the townspeople. They each carry 12-13 rounds of 5.56mm ammo. Most of the time they will catch you, but there are no consequences for being caught other than not being able to pickpocket the same soldier again. You WILL lose karma for pickpocketing the soldiers. (tested on the PS3 version only, after you pickpocket a soldier, they will shoot you so make sure you save before trying.)
  • The Chinese Soldiers will entirely ignore the player, Doc, and Betty; even standing in front of them while they fire will cause you to take no damage, and attacking or rendering them unconscious will not turn them hostile. The bodies cannot be looted; trying to activate them does nothing despite the "Search Chinese Soldier" message, and eventually, the soldier will stand back up and start fighting again. If you attempt to talk to the Chinese Soldiers, they will always reply with "Stand aside comrade! We'll deal with these imperialist pigs!"
  • If you pickpocket Braun/Betty after you enable the Chinese attack, the soldiers will attack her, because she turns violent and starts to punch you. She won't die from the bullets from the Chinese soldiers, but she will be attacked for eternity by them.
  • Braun states that the simulation has been running for 200 years, and that his body (and presumptively the rest of the subjects') would no longer cope with any physical activity, especially not that typical of daily life in the post-war Wasteland.
  • If you kill anyone within the simulation, trying to loot the body will result in an in-game error about the simulation preventing you from tampering with corpses.
  • Through a series of console commands, the player can make Braun come out of the tranquility chamber. When you try to talk to him, he speaks in a southern accent. The only dialogue you can say is "I have to go now".
  • Attacking Braun/Betty in the simulation with a weapon like the rolling pin or knife, or even your fists, will cause a severe retaliation and instant death for the player (in what appears to be the form of a Pulse Grenade explosion). If you talk to Braun after activating the fail safe, he says you can leave because he can no longer harm you - however, he can still instantly kill you if you attack him/her.
  • If you have the Mysterious Stranger perk, he will still show up during V.A.T.S. in Tranquility Lane (That's, if you decide to do things the violent way).
  • If you take the more violent way of killing all the residents of tranquility lane and then activate the fail safe system, when you head back outside you'll see every resident you murdered back alive and being slaughtered by the invasion of Chinese. You will still gain good Karma for doing so.
  • The main musical theme heard in the simulation can be faintly heard at a much slower tempo in the quest Baby Steps.
  • Upon leaving the simulation, James is wearing the standard Vault 101 uniform, not the required Vault 112 uniform needed to access the simulation
  • The leaves on the trees in the background are actually only 2D, and will pivot to the camera so you will always see the same image. (Much like the trees/scenery in Doom)


  • This level has a a nasty screen freezing bug:
  1. Open up the fallout.ini file in: My Documents\My Games\Fallout3
  2. Find the line: bUseThreadedAI=0
  3. Change it to: bUseThreadedAI=1
  4. Add another line after it and insert: iNumHWThreads=2

This will limit the game to 2 cores and prevent the engine bug from causing the game to freeze.

  • For some reason Mrs. Rockwell can skip the argument with her husband if you decide to use the sexy sleepwear. She will just run away when she's within speaking distance of her former husband. One way to avoid this is to exit the basement before she does and make sure Mr. Rockwell is not too close to the basement door.
  • On the Xbox 360 version, it is possible to cause the game to hang by pressing B after either finding the rolling pin or being killed by Betty/Braun.
  • On a rare occasion, you may have to do 3 games for the girl before you can get to the failsafe.Possibly because she has to finish the song before you can go forward.
  • Rare- sometimes when the player hits Betty, the character freezes as if in speech, but is able to move the camera; Betty runs off like normal children and the player must reload the game. (found this when an attack aimed at Martha Simpson hit Betty instead) (Confirmed on PS3)
  • If you have completed the Operation: Anchorage DLC, have the Winterized T-51b Power Armor in your inventory, and are currently doing the quest You Gotta Shoot 'Em in the Head, you may get a message after leaving the simulation that You Gotta Shoot 'Em in the Head has been completed. This is effectively the same bug that occurs when you first receive the suit at the Outcast Outpost.
  • There is a possibility that your follower will not return to their original location upon entering the simulation, and instead disappear (Confirmed on PS3/PC with Charon/Dogmeat)(Confirmed Charon Xbox 360).
  • It is possible that if you pickup the rolling pin before doing game 4 and then try to do game 4 with it in your hand, the Pint-Sized Slasher mask and knife are both not there. The only way to fix this is to reload or to activate the failsafe. (confirmed Xbox 360)
  • While arranging a creative death for Mabel Henderson, it's possible for her to become stuck in the Simpson house for a while, alternating between fleeing mode and staring at the ceiling. It might take the player some time to get her on her way back to her residence and the traps that await her. A stock conversation with another NPC is what shook her loose. (Xbox 360)
  • By jumping over a low fence in the back yard of the abandoned house, you can actually leave tranquility lane, and there is nothing but blank, see-through terrain, except for an island with a palm tree on it, but disappears when you get close to it.(confirmed ps3) On The Xbox 360, the low fence was behind the Rockwell house, and no such island could be found.
  • If you have the military school brochure with you and choose to activate the fail-safe while the quest objective "Make Timmy Cry" is running, it may get marked completed, even if you haven't even talked to Timmy.
  • If you kill everybody in the simulation and then use the fail-safe all the residents will be alive again, you will get positive karma, and Betty will still hate you. (Confirmed 360)
  • If your health is not full upon entering the simulation and you replenish it, it will be full upon exiting
  • When entering Mabel Henderson's house in order to arrange for her creative death, she may possibly leave the house just as you are entering it, without giving the player a chance to speak to her. The player can go through the home and setup any or all of the available traps as required, however Mabel never comes home to spring any of the traps. Worse yet, upon trying to exit the home the player will find that the door to Tranquility Lane is now locked (and a key is required to open it) and they are unable to leave. Sleeping or waiting for Mabel up to 72 hours does not cause her to return. The only recourse is to load a previous save. (Xbox 360)
