Medallion Locations: Fallout 4 Nuka-World
When you finally reach Nuka-World after surviving that brutal Gauntlet, you will come across a Nuka-World Informational Robot Assistant, or N.I.R.A. for short. This odd robot (who has some insane dialogue at times) offers you a quest in exchange for a special prize. The quest is simple, collect seven medallions located around the park and then return them to N.I.R.A.
You can find each at:
Dry Rock Gulch – This one is located in Mad Mulligan’s Minecart Coaster. You’ll need to enter this ride’s building for the area’s quest, to clear out the Bloodworms. Once inside, make your way through and before the end you’ll reach a gift shop (it has the chained door) where you’ll find the medallion dispenser.
Kiddie Kingdom – Look for the Ferris Wheel then start checking around its base. You’ll find a dispenser here.
Kiddie Kingdom – This one is located next to a ride that isn’t on your map. Just west of the Fun House is a Nuka Racers ride. Look for the boarding area and you’ll find a medallion dispenser there.
Galactic Zone – You should find this one easily as you run through the Vault-Tec: Among the Stars attraction. It’s right next to the exit before you leave.
Galactic Zone – You’ll need to go all the way to the end of the Nuka-Galaxy ride. When you’re at the end, there will be some steps, climb them and look to your right.
Safari Adventure – This one is located in Cappy’s Tree House which you’ll find as a part of the area’s quest. You’ll find the medallion dispenser on the first floor, to the right of the balcony.
Bottling Planet – Head towards the World of Refreshment but don’t go inside. Look for the lines, which are marked by railings, and you should find the dispenser outside near this area.
Now all you have to do is return all of these to N.I.R.A. to receive some useful bottles of Nuka-Cola. Enjoy the rest of your stay in Fallout 4: Nuka-World.
