Now that the Call of Duty x Fallout crossover has begun, a new event aims to increase the excitement with a lineup of exclusive items. There are a ton of new cosmetics to equip, but the one you may have your sights on is the mesmerizing Nuka-Cola Quantum weapon skin. Here’s a look into all the challenges and rewards in the MW3 and Warzone Fallout: Vault Dwellers event.

Similar to the Vortex Virus Mainframe event, players must accumulate a substantial amount of XP to unlock rewards in Fallout: Vault Dwellers. This can be achieved by participating in a variety of game modes, including MW3 Multiplayer, Zombies, or Warzone. For an additional boost of 2,500 XP per match, equip the Vault Dwellers Tracer pack and play as Vault 141 Gaz, Ghost, Price, or Soap.

To see a sneak peek, take a look at the entire Fallout: Vault Dwellers reward collection in MW3 and Warzone:

XP Needed	Rewards	Reward Previews
10,000 XP	Slocum’s Joe Weapon Sticker
20,500 XP	Double XP Token
37,200 XP	New California Republic Large Decal
55,000 XP	Double Weapon XP Token
78,000 XP	Nuka-Cola Charm
105,000 XP	Tier Skip
140,000 XP	Nuka-Cola Caps Emblem
180,500 XP	Everyone Disliked That Calling Card
200,000 XP	Double Battle Pass XP Token
225,000 XP	Nuka-Cola Quantum

If you want to get XP faster, participate in game modes like Hardpoint or Ground War. I also found Kill Confirmed highly beneficial for this, as it racks up XP quickly every time you pick up a dog tag. But if you want an even faster method, exchange 2,800 COD points for the Vault Dwellers Tracer Pack.

The Nuka-Cola Quantum is the very last reward you can earn, showcasing a Mastery camo for any weapon. Since it requires 225,000 XP, players must participate in multiple rounds before the event ends.

According to the Call of Duty Blog, the Fallout: Vault Dwellers event concludes on June 26, 2024, at 8 a.m. PT/ 10 a.m. CDT/ 11 a.m. ET. That only leaves you about five days to complete the challenge, so make the most of your time and play several rounds in Call of Duty daily.
