The Vault-Tec Workshop DLC in Fallout 4 allows players to step into the shoes of an Overseer and run experiments inside Vault 88. Among these tasks, The Watering Hole stands out as a key quest focused on testing a prototype Soda Fountain on your vault dwellers. Navigating this mission requires retrieving specialized research before configuring your equipment to observe the results.
Retrieving Research from HalluciGen, Inc.
To begin the experiment, Overseer Barstow tasks you with gathering chemical formulas from HalluciGen, Inc. Traveling to this location presents several environmental hazards and hostile Gunners patrolling the hallways. You must navigate through the facility to find the chemical research stored safely inside a trunk near the chemistry lab.
Clearing the building requires caution, as rogue gas and disoriented enemies make traversal unpredictable. Once you secure the research notes, exit the building and return directly to Vault 88. Handing the formulas over to Overseer Barstow will unlock the next phase of your vault management duties.
Constructing the Soda Fountain Prototype
After delivering the research, you must open the workshop menu to craft the Soda Fountain Prototype. Place the prototype in a central location within Vault 88 where settlers can easily access it. You will also need to construct a medium power generator and connect a terminal to the system.
Proper wiring is crucial to ensure the terminal can interface with the prototype without power interruptions. Accessing the terminal menu allows you to choose the chemical parameters for the upcoming trial. Each parameter selection changes how the dwellers react to the beverage distributed by the machine.
Selecting Experimental Parameters and Monitoring Dwellers
The terminal offers three distinct settings for the Soda Fountain: Appetite Suppressant, Mood Enhancer, or Generic Caffeination. Choosing an option determines the social and physical impact the drink will have on your subject, Clem. Once you set your preference, let Clem serve drinks to the vault residents for an hour.
You can wait or complete other crafting projects while the hour passes to observe the trial's outcome. Speaking with Clem after the test provides direct feedback on how the experiment affected him. Conclude the quest by reporting your findings to Overseer Barstow to earn experience and unlock the final prototype missions.
