The Third Experiment
Overseer Barstow is ready to start her next experiment, but it will take a significant amount of Nuclear Material to construct her latest device. If needed, use the Workshop menu to scrap the uranium deposits located throughout Vault 88. Otherwise, construct a Phoropter and attach it to a terminal and power source.
Select the desired experiment parameters and wait for Overseer Barstow, Clem, and an additional settler to gather around the Phoropter Prototype. Speak with Overseer Barstow and observe the impending experiment.
Experiment Parameters: Phoropter
| Name | Effects | Barstow Reaction | Settler Reaction |
|---|---|---|---|
| Subliminal Messages | Phoropters produce increased Happiness, consume twice as much power, and have a small chance to kill their users. | Very Positive | Negative |
| Vault Monitoring | Phoropters produce decreased Happiness, but have a very small chance to kill their users. | Relatively Positive | Negative |
| Improved Eye Care | Phoropters will have no adverse effects. | Negative | Positive |
When the experiment ends, speak to the test subject. Depending on the choices you made up to this point, the conversation will go one of three ways:
- If all three of the completed experiments elicited positive reactions from the settler, she is pleased with her decision to stay in Vault 88.
- If only two of the completed experiments elicited positive reactions from the settler, she’ll attempt to leave the Vault. At this point, you can attempt to convince the disgruntled settler to stay.
- If two or more of the completed experiments elicited negative reactions from the settler, she’ll storm out of the Vault. In this case, no amount of pleading will convince her to stay.
Once you’ve finished speaking to the test subject, report to Overseer Barstow to complete the quest. The resulting Phoropter variant can now be built at any Settlement under your control.
