I would also like to add the NPC who gives you the Quest, Sierra Petrovita, has a ton of regular Nuka-Colas in her home in Girdershade. Tip: 10 regular Nuka-Colas (not Ice Cold) = One Quantum The Quantum Chemist Perk does indeed allow you to complete the Quest if you are running low on Quantums. We recommend sticking with Sierra because, according to the Fallout Wiki, giving the Quantums to Roland will cause you to lose Karma and you don't want that (unless you're going for the Bad Karma trophies that is).ġ: Scavenge 30 bottles of Nuka-Cola Quantum from the locations in the link below.Ģ: Install the Broken Steel DLC, hit Level 22 and take the Quantum Chemist Perk (doesn't work with Ice Cold Nuka-Cola) then convert 300 bottles of Nuka-Cola into 30 Quantums (credit to x410xDragon for confirming this actually works). After accepting the Quest and leaving Sierra's home, her 'boyfriend' Ronald Lauren will stop you and ask you bring him the Quantums instead. To make your life easier, complete the optional part of this Quest and retrieve the Shipping Manifest from the Nuka-Cola Plant.

Once you receive the Quest, you'll need to recover 30 of the 108 bottles of Nuka-Cola Quantum that are to be found hidden throughout the game (there are 94 bottles if you don’t have the DLCs). You will get this Quest from Sierra Petrovita in Girdershade which is Southwest of Smith Casey's Garage, after taking her Nuka-Cola Tour. This is an example of what a bottle of Nuka-Cola Quantum looks like: Also, make sure your Companion waits outside as they have a nasty habit of killing Sierra. If she doesn't snap out of it, even after waiting or Fast Travelling away then back again, all you can do is load a much earlier save. WARNING: If Sierra is in 'Fleeing' status when you visit her, then search the surrounding area for any enemies that have spawned and kill them.

Do not drink, sell or make Nuka grenades out of any bottles of Nuka-Cola Quantum you find before completing this Quest otherwise you will not have enough to get the trophy.
