In NV ive found two different types of Nuka Cola Variants "Nuka Cola Quartz" and "Nuka Cola Victory"

They both look pretty sweet, one glows red and one glows gold? i think

Im wondering if anyones found any other of these variants, maybe someones found the original variant "Quantum" Which had the purple glow which was the coolest!

Also wanna know if they have any part in the game besides a new variant which you can use to heal? Maybe they can be used for a quest?

The only other variant is an Ice-Cold Nuka-Cola.

Thats not really even a variant though? It just heals a little more if i remember correctly

In FO:3 you got those when you put them in the nuka cola machine you bought for your house in megaton.

How do you get them "ice cold" now
put them in a nuka cola fridge maybe??
im just guessing
