The vault was one of the long-awaited easter eggs during a recent patch for Warzone.
While players can assume we will be able to access the vault during next season, one can never be too sure.
Here's how to complete this Warzone Easter Egg.
How To Open The Vault Doors In Warzone
Here's how to open the vault doors in Warzone:
Key cards can be found in select loot boxes - they are VERY rare to find.
The key cards will only work on vault doors 0, 4, 5, 6 and 9.
Inside the vault is TONS of loot including weapons, cash, streaks and more.
Key cards are not specific like they are in other games, one key card will access any vault.

Rumours about an easter egg within the map have been bubbling for a number of weeks, since its launch in March.
With the Bunkers now being accessible, a few other clues are now popping up around the map.
@ModernWarzone has alerted the community that there is an interactable red button.
The doors for Bunker 11 appear to have a war room, server room, mist room, and more. Along with a big shiny red button in the war room and a nuclear warhead inside of the bunker!
