Fallout 3

You'll be wanting to look out for the Nuka-Cola Quantum bottles from the moment you start the game. There are well over a hundred of them, and you can find at least one pretty much everywhere you go. You will need 30 bottles of Nuka-Cola Quantum total. Keep an eye out for a purplish-blue glowing soda bottle wherever you go and make sure you don't use them or sell them. The girl who wants them lives in a two-house settlement in the southwest corner of the map.

A few locations where you can find multiple bottles:

- Nuka-Cola Machines - Every time you open one of these for the first time there's a random chance they'll have a Quantum in them.

- Eulogy's Pad in Paradise Falls - There are several stashed near the staircase in crates.

- Nuka-Cola Plant - located near the southern border of the map, near the center. There's a conveyor belt you can activate. You can get a few bottles from it before it breaks down.

- Nuka-Cola Truck south of Old Olney (northeast corner, east of Vault 92). There's an abandoned Nuka-Cola Truck with several bottles inside.

This a good achievement to work on while you're exploring for your 100 locations, 50 terminals, and 50 locks. Just check all the markers you run into on your map and search each location...most places have at least one terminal, lock, and Quantum.

UPDATE:

When you come back with the bottles the man outside will try to buy them from you so he can get in god favor with the girl. Keep in mind here that you can only get the Nuka Cola Grenade schematic by giving them to the girl. Also, all 30 Quantums have to go to one NPC, meaning you can't give one 10 and the other 20 to complete the quest. Some people give the guy 29 and the girl 30 so that they can get a ton of caps but still get the schematic.

Broken Steel, the third DLC expansion for Fallout 3, has added another way to get this achievement. If you have at least a science skill of 70 when you hit level 22 or higher, you'll have access to the Quantum Mechanic perk. This perk allows you to turn 10 Nuka Colas into one Nuka Cola Quantum, thus speeding up your progress with this quest. It does not, however, work on the Ice Cold Nuka Colas that you get from your machine. You MUST have the Broken Steel expansion to raise your level above 20 and gain access to this perk.

WARNING:

If you already have 30 or more Nuka Cola Quantum bottles when you first meet the girl, don't give them all to her at once. ThrillaGnat has found that if you immediately give her all 30 in the initial dialogue she won't give you the grenade schematic, so make sure you end the dialogue and restart it before you give her all 30 bottles.

These are the locations of all the bottles in the game not in vending machines though because there random.

Also the number represents how many quantums in each area

here is a guide to the locations of the cola. it helped me out. hope it can help u out as well.

To clear up any confusion. The settlement Sebatian is referring to is a town called Girdershade. This is Not your only chance to get the Nuka Grenade schematic. But if you do not have it you will want to cough up the 30 bottles of Quantum to Sierra NOT Ronald!

Just a tip , if you aren't bothered about recieving bad karma, although it didn't really affect my good karma to much, then head straight over to seirra's house in Girdershade ( at around levels 20 - 25 you can gain the perk to turn 10 bottles of nuka cola in to a quantum cola , if you have science 70 and above and obviously have the broken steel DLC) she has around 60 - 70 bottles of nuka cola which you can turn into quantum. Now if you were on the lookout for quantums throughout the game then you should ( well i did ) have around 20 bottles already which makes it an easy task of only 10 to collect.

Hope it helps :)

Also, get all the dlcs to help you with this quest, as the ones that add new areas also add new vending machines (e.g. In Point Lookout), where it is possible to find nuka-cola quantum. This might help if you are struggling to find any in the main game.

If you're struggling, these videos from Orcidea on youtube may help.
