I play Fallout 3 on the Xbox 360 so I don't know any mods to get more quantum. I know about the Nuka Chemist perk but you get it at level 22. I couldn't wait that long. So about the third time I played the game I started to save my regular Nuka-Cola and stored it in the frige at the Megaton house you live in if you save Megaton. When I collected all of the Quantum and gave it to the girl in Girdershade. Then I started to collect them for myself. The Quantum is rare if you don't have the mod or the perk yet. You can find the other materials just about anywhere. Well I will admit Turpintine is a little difficult to find.
When I do create Nuka Grenades I all ways save them for something big like Brawlers from Point Lookout or a large group of Enclave Soldiers. You have to admit the explosion is pretty cool.
How many of you have done the same or thought the same?
