Call of Duty: Warzone's Rebirth Reinforced event is still in full swing on Rebirth Island, and the fourth community challenge is now live and teasing a "Golden Vault" mystery.
Mysterious bunkers aren't new to Call of Duty: Warzone, as the battle royale's original Verdansk map also launched with bunker Easter eggs of its own. However, three "golden" vaults were added to Rebirth Island with Season 2 Reloaded's major map update. The vaults are still currently locked, but a new challenge is now live in the Rebirth Reinforced event to let players work towards a community goal of unlocking them.
The currently locked vaults can be found by visiting the underground area near the Nova 6 factory, the cliffside between the Stronghold and the Living Quarters area of the map, and a third is below the shack found between the Dock and Bioweapons Lab.
