Modern Warfare Zombies' massive open-world mission area hides many secrets for players to uncover, whether through progressing the four acts of story missions or simply hunting through Urzikstan looking for hidden Easter eggs. One secret that players can uncover is hidden in the tunnels below the Shahin Manor in the southeast quadrant of the play area: the Terminus Outcomes Mercenary Vault. Loaded with an ammo resupply and several aether crates filled with legendary gear and rewards, players can easily get geared up for deployment if they can unlock the vault and access the goods inside.

To open the vault, players will have to scour the map for four radios, which will transmit unlock signals to the vault in the H7 sector of the map. Once players can transmit all four signals, the vault can be opened and the loot can be accessed. To gain access to three of the four radios, players will have to defeat three mercenary mini-bosses: the Rook, the Knight, and the Bishop. Here's how to beat them all and open the treasure trove.

Defeating the Mercenary Mini-Bosses & Obtaining Transmissions

The Rook

The Rook is a Sniper mercenary mini-boss located in the Southwest of Urzikstan, south of the North/South bridge just south of Levin Resorts. In the hotel just west of the highway in the C5 sector, the Rook will be posted on the top floor, taking shots at any players or zombies who get too close. Preferably, players will want to find a nearby redeploy drone or jump portal and parachute directly to the roof to approach the Rook.

Modern Warfare Zombies - Vault - Rook Map(1)
Players will find the Rook on the west side of the map in C5.

If players cannot find a quick way to parachute to the roof of the hotel, they will need to carefully push up from the first floor via the south side staircase. The staircase will be lined with mines, so advance slowly up the flights of stairs, keeping an eye out for red blinks to give away the position of the enemy defenses. The Death Perception perk will let players detect these mines, which will be outlined in the red glow of the perk effect.

Alternatively, players can use zombies as bait for the mines. Lure large numbers of zombies to the hotel and use decoy grenades or the Aether Shroud field upgrade to pull the zombies' focus off of players. If players can get zombies to chase after the Rook and ascend the stairs, they can use these zombies as decoys for the proximity mines defending the staircase.

After players gain access to the top floor, take out the sentry gun and push through the grunts to find the Rook. Quickly drop him with headshots. Once defeated, use the Rook's radio to transmit his signal to H7.

The Bishop

The Bishop is a recon mercenary mini-boss posted in the train tunnel on the north side of the map. Follow the train tracks on the northern edge of Urzikstan through the tunnel in the D1 sector. Once players proceed deep enough into the tunnels, several smoke grenades will detonate, and the Bishop and his guards will spawn.

The Bishop is only lightly armored, but does have a large health pool. Players can quickly defeat the Bishop and his goons using any heavy rifle and aiming for headshots, or by simply driving a vehicle through the tunnel and aiming for the smokescreens. The Deadshot Daquiri perk is immensely helpful for rapid target acquisition and quick elimination of the Bishop.

Once the Bishop is defeated, interact with the radio next to his body to transmit his signal to the vault in H7.

The Knight

The Knight is a Shocktrooper with heavy armor and an LMG, found in the Northwest area of the MWZ mission area. Follow the train tracks from where the Rook is posted towards the tunnel where the Bishop is found. Similar to the mercenary convoy from the Interceptor Mission, the Knight will be riding in the back of an armored pick-up truck following this stretch of tracks.

Be ready to disable the truck and eliminate all occupants. Once the truck is disabled, the mercenaries inside will exit and begin firing on you. Be careful not to let the Knight focus on you, as he will quickly break all armor plates and drop players' health with his heavy LMG. Cluster mines or scatter mines can be placed along the path of the truck to instantly disable the truck as it passes. Alternatively, wonder weapons like Kazimir Devices or the Ray Gun will almost instantly destroy the armored vehicle and those inside.

If players do not have any wonder weapons or explosives on hand, attempt to shoot out the tires on the vehicle, or the driver, to prevent the vehicle and the Knight from escaping. Once the Knight is defeated, transmit his radio signal to H7.

The Pawn Transmission

The final transmission is located in the northeast corner of the map in the I1 sector, and is the only transmission not guarded by a mini-boss. Follow the waterline north of the Orlov Military Base heading east until you find a building on the shore. Inside, players will quickly find the radio to send the transmission to H7. Immediately after sending the transmission, zombies will spawn in and flood the building, so be ready for a fight.

Players will be able to loot several small loot crates in the building that are full of armor plates. Be sure to stock up if armor reserves are low.

Opening The Vault in H-7

Players will find the Vault in the tunnels beneath the Shahin Mansion, located in the H7 sector of the map. Search the mansion for an ascension line that leads down to secure tunnels. In the innermost room, players will find a radio terminal and a locked room with several Aether Loot Crates inside. If all four transmissions have been sent, players can open the vault, gaining access to the loot inside.

Modern Warfare Zombies - Vault - Shahin Manor

Keep in mind that transmissions and loot in the vault are shared across all 24 players, so if another squad has already sent a transmission, players may not be able to find that radio. If you notice another team in the game going after the bosses and sending the transmissions, be sure to head to the vault immediately to be the first to open the doors and access the loot.

Be cautious of the loot crate near the ammo resupply, as it is a Mimic in hiding. Quickly drop this mimic, then search the remaining crates to acquire a handful of ultra-rare equipment and several gold bars that can be sold for a $3500 essence apiece.
