With the launch of Call of Duty: Warzone Season 4, a familiar loot mechanic is set to debut in Caldera: bunkers of loot with restricted access.
There are now seven main Mercenary Vault bunkers on Caldera for players to discover and to access them, you need a Key Card. Here's a breakdown of the Mercenary Vault locations and how to open them in Call of Duty: Warzone Season 4.
Warzone Mercenary Vault Locations: Full List
As indicated on the Tac Map above with yellow circles, the seven Mercenary Vaults can be found in the following spots:
- Between Lagoon and Airfield
- North of Fields
- Outside Resort
- East of Power Plant
- Below Runway
- South of Docks, towards Factory
- Between Digsite and Mines
Warzone Mercenary Vault: How to Open
Essentially, these work just like the bunkers from Verdansk, except players will need a Key Card to access them instead of pre-arranged codes.
A Key Card is bound to the player who picks it up and can only be used once on any of the seven bunkers.
Key Cards are rare drops that can be obtained from Supply Boxes, Contracts or other players who found them during the game.
Once used, the Mercenary Vaults will open to reveal some major loot: Weapons,
ammo, Killstreaks, Cash and Field Upgrades. Players are urged to get out quickly, however, because there could be other squads trying to ambush and take the spoils for themselves.
During the limited-time Mercenaries of Fortune event, players who open a Mercenary Vault in Caldera will also complete the "Minted" challenge, which nets them a Rare "Fanged Assault" Emblem.
