Warzone Mercenary Chest Locations: How to Open

With the release of Call of Duty: Warzone Season 4, a familiar loot mechanic is expected to be released in the caldera: limited-access loot bunkers.

Now that the caldera has seven large Mercenary Vault bunkers for players to explore and access, you need a keycard. Here is a detailed breakdown of Mercenary Vault locations and how to unlock them in Call of Duty: Warzone Season 4.

As shown on the Tac Map with a yellow circle above it, seven basement rentals can be found in the following locations:

Essentially, they work like Verdunski’s bunkers, except players need a keycard rather than pre-agreed codes to access them.

The keycard is bound to the player who receives it and can only be used once in one of the seven bunkers.

Key Cards are rare drops that can be obtained from Supply Boxes, Contracts, or other players they find during the game.

Once used, Mercenary Chests will be opened to reveal some of the great loot: weapons,
Ammo, Kills, Cash, and Field Updates. However, players are advised to flee quickly, as other detachments may have attempted to ambush and take the loot themselves.

Players who open a Rented Caldera Vault during the limited-time Mercenaries event will also complete the “Minted” quest, granting them the rare “Fanged Assault” emblem.
