At the start of Chapter 6, you find yourself stuck in a simulation program – Tranquility Lane. You need to find a way out and figure out how to save your dad from the same hellacious fate.

You could go the Evil Way and do what Betty asks – which ends with you murdering everyone – or be a good little angel and end the simulation for good. Old Lady Dithers clues you in to a failsafe terminal in the simulation, and by accessing it you can end Dr. Braun’s evil experiment.

Ultimately, he’ll answer all of your questions and let you and your father return to Vault 112.

Illustrated Walkthrough

First things first. Here’s a quick walkthrough, by way of screenshots, on how to access the failsafe terminal and escape Tranquility Lane.

Details, In Writing, For You Readers

For those of you that prefer text to pictures, here’s a more detailed walk through.

First, find Old Lady Dithers and speak with her. She might be walking around town, or you can find her in the Dithers residence (northeast corner of the circle).

She’ll fill you in one of the grittier details about Tranquility Lane and tell you that there is a Failsafe Terminal inside the Abandoned House. This is your Good Karma ticket out of here.

Second, enter the Abandoned House. It’s at the northern point of the circle. Inside, you’ll find a collection of items. Clicking each item produces a tone and creating the proper song will make the failsafe appear.

If you want to succeed through trial and error, go listen to Betty and pay attention to the background music. Try to repeat the melody by clicking on the objects in the house.

As you attempt to hit the notes in the right order, the game will play the correct tone after a series of incorrect tones. So keep clicking away, and make a note of the tones that the game plays back.

Or, cheat a bit and click them in the following order:

1. Radio
2. Glass Pitcher
3. Garden Gnome
4. Glass Pitcher
5. Cinderblock
6. Garden Gnome
7. Glass Bottle

This is one of the more obscure puzzles in the game, so don’t feel bad if you had to cheat a bit. I did the first time through.

Third, activate the failsafe terminal and read through the plot information. You’ll find out lots of stuff about Braun and his experiments.

When you’re done, read the documentation about the Chinese Invasion program and then activate it. This will summon a bunch of Chinese soldiers to murder everyone – for real – and leave Braun alone in his simulation for eternity.

Fourth, go to the playground and speak to Betty. Braun will reveal his true identity and answer any questions that you have. He’ll be a bit put off, since you damned him to an eternity of loneliness, but whatever. He had it coming.

He’ll eventually fill you in on the fact that your dad is the dog, and you can leave by using the door that appeared.

Fifth, head through the door. Back to reality! Now you’re back in Vault 112.

Your father, James, will get out of a nearby tranquility lounger. Speak to him for a bunch of plot development. He’ll eventually ask you to head with him to Rivet City, where you begin… Chapter 7!

Or have a go at the Bad Karma option. It’s a bit more… entertaining. You can start by making Timmy Neusbaum cry.

Or if you’re bored of Tranquility Lane, move on to Chapter 7.
