Similar to theVortex Virus Mainframe event, players must accumulate a substantial amount of XP to unlock rewards inFallout: Vault Dwellers. This can be achieved by participating in a variety of game modes, includingMW3Multiplayer,Zombies, orWarzone. For an additional boost of 2,500 XP per match, equip theVault Dwellers Tracerpack and play as Vault 141 Gaz, Ghost, Price, or Soap.
To see a sneak peek, take a look at the entireFallout: Vault Dwellersreward collection inMW3andWarzone:
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 may 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 theCall of DutyBlog, theFallout: Vault Dwellers event concludes on May 22, 2025, 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 inCall of Dutydaily.
