Detailed walkthroughEdit

Overseer Barstow will tell you the next experiment requires a package from HalluciGen, Inc. which was never delivered due to the bombs.

The shipment is in the loot chest in the final room after navigating the building, and therefore is easier to use the back entrance facing the Charles View Amphitheater once the door is unlocked, if you have cleared it before.

Barstow will then reveal that the next vault productivity 'hazard' is hydration breaks. The notes reveal plans to introduce chemicals into the soda fountain you build, to different effects: Mood Enhancer, Appetite Suppressant, or Generic Caffeination. Using a terminal, select which parameters you wish to apply. Again, once you decide, you cannot change, and various responses from companions may occur.

Allow Clem to serve drinks from the fountain for an hour, and await the results from Barstow. Like before, they will reflect what the R&D team in each parameter description discovered. The mood enhancer option will also permanently affect Clem's mood, making him more positively-inclined towards everything.

After completing the quest, the soda fountain can be mass produced. It's located on the Vault tab under Resources, while on workshop mode. The stats of the fountain depend on the experiment option that was chosen, although all versions require 2 units of power regardless of the experiment.

  • Selecting the mood-enhancer experiment option makes the fountain provide 15 points of happiness, without any risk of death.
  • The appetite suppression option provides 5 points of happiness and 1 unit of food, at the risk of killing random non-essential settler (1% chance per day).
  • The regular caffeination option also provides 5 points of happiness, without any risk of death.

  • pcIcon pc Attempting to talk to Clem after he has served drinks for an hour may produce a glitch, where Clem responds "You here to check up? I got a customer right here," but won't progress to the next stage of the quest. The settler who arrived with Clem must be present at the soda fountain so she can talk to Clem before the quest will complete.[verified]
    • A possible fix is to wait a few hours and/or leave the vault and re-enter, then she will be standing beside him.
    • It is also important that the Soda Machine is in a location accessible to the settlers. After Clem and the settler finishes their dialogue, the quest stage is complete.
