Warzone Mercenary Vaults locations

Warzone Season 4 introduced secret Mercenary Vaults for players to discover around Caldera, which can only be accessed by finding a Golden Keycard. Here’s how to get your hands on a Keycard, and where to find each vault on the map.

Warzone Season 4 is finally here, and it’s done plenty to shake up the formula in CoD’s battle royale title. On top of the expected new guns and weapons adjustments, Raven pushed the boat out with an entirely new map called Fortune’s Keep.

The new season has also started with the special Mercenaries of Fortune event, giving players a host of challenges to complete to earn shiny rewards. One of these challenges tasks players with opening up a secret Mercenary Vault somewhere on Caldera.

These hidden bunkers require a Golden Keycard to access, so we’ve put together a guide on exactly how you can get hold of one and where each Mercenary Vault can be found.

How to find Golden Keycards in Warzone

Before you try and plunder a Mercenary Vault, you’re going to need a Keycard to open the door. There are three different ways you can obtain one in Warzone, and we’ve listed them all below:

  1. Looting Supply Chests
  2. Pick up from an eliminated player who had one in their inventory
  3. Completing Contracts

Unfortunately, all three of these methods rely heavily on luck and there is no way to guarantee that you’ll stumble across a Golden Keycard. But you can improve your odds by tweaking how you play.

Keycards have a higher chance of spawning in Supply Chests found in High Tier Loot Zones, so dropping into one of these locations will drastically help your chances. Contracts will randomly award Keycards upon completion too, so pick up as many as you can.

Once you’ve managed to acquire a Keycard, the next step is to find one of the seven secret Mercenary Vaults scattered around Caldera. Luckily, the locations are marked on the map by a gold circle, so you shouldn’t have much trouble tracking them down.

To make things even easier, we’ve listed where you can find each one below:

  • Between Lagoon and Airfield
  • North of Fields
  • Just outside Resort
  • To the East of Power Plant
  • Below Runway
  • South of Docks, towards Factory
  • Between Digsite and Mines

Once you’ve found your way inside the vault, you’ll be met with a keypad. Simply interact and the goodies inside will be all yours.

What’s inside Mercenary Vaults?

Before you go through the hassle of opening a Mercenary Vaults, you might be wondering if it’s worth your while. On top of being a requirement for one of the challenges in the Mercenaries of Fortune event, these bunkers can also help you to victory.

Once you head inside, you’ll see a boatload of Supply Chest for you to open, including the extra valuable red chests. These will give you the following rewards:

  • Weapons, including rare Blueprints
  • Killstreaks
  • Cash
  • Ammo
  • Field Upgrades

There can be over ten Supply Chests in each vault, so it’s definitely worth you and your squad trying to access one, as there’s more than enough loot to go around.

Warzone players call for major LMG buffs as Assault Rifles dominate meta

Warzone players are sick of Assault Rifles dominating the meta so are calling for LMGs to receive major buffs.

Although supposed to be long-range powerhouses, with a few exceptions, LMGs have never broken into Warzone’s meta for long. Claiming that LMGs have no identity, players are calling for major buffs.

Although weapons come and go from Warzone’s meta, how the guns behave has almost always stayed the same. Players always stick with a long-range weapon with low recoil and a large mag size, and a lightweight SMG with a fast TTK.

The long-range weapon has almost always been an Assault Rifle or an LMG that’s been built to act like an Assault Rifle, and players are growing tired of it. With a couple more Warzone Pacific seasons left and Warzone 2 on the horizon, players are calling for major LMG buffs so they’ll have their own identity.

Although a couple of LMGs such as the Bruen Mk9, MG82, and Bren have made their way into Warzone’s meta, the class as a whole has never come close to the popularity or efficiency of Assault Rifles.

Reddit user IonlyPlayAOE3 explained why LMGS have a “sh*t identity” in Warzone, laying much of the blame on Vanguard weapons’ ten attachments. They explained that an Assault Rifle can do everything that an LMG can, especially by holding at least 60 rounds.

They hope that LMGs will have much more of an identity in Modern Warfare 2 and Warzone 2, where Assault Rifles should “struggle against LMGs in long-range to ultra long range engagements.”

Many players agreed, wanting an Assault Rifle to become a middle ground between LMGs and SMGs. “They should lose to LMGs at range, and lose to SMGs up close, but be a decent middle ground,” explained Shielo34.

However, some worried that buffing LMGs would just make them replace Assault Rifles in the meta. Instead of giving LMGs straight buffs, some suggested lowering Assault Rifles’ magazine size.

Warzone players were starting to catch on to Season 4’s UGM-8 LMG and its burst-fire barrel, but the devs were quick to nip that in the bud with the June 30 update. With the NZ-41 now nerfed as well, we’ll need to wait and see how the post-nerf UGM fits into the Season 4 meta.

Warzone Pacific Season 4 received a plethora of balancing adjustments in the June 30 patch, with some of the best attachments in the game getting significant nerfs.

The June 30 Warzone Pacific patch brought a ton of weapon balancing changes in Season 4, including a nerf to the popular NZ-41, which the developers felt had become too overpowered over the last season.

Other weapons like the H4 BlixenMarco 5, and UGM-8 were also changed in the update. Warzone players will be encouraged to alter their usual loadouts as the best attachments have also been nerfed.

Warzone Pacific Season 4’s June 30 update patch included nerfs to the Lengthened ammo type, MX Silencer muzzle, and M1941 Handstop underbarrel. These attachments are popular choices on Assault Rifle loadouts.

The MX Silencer and Lengthened ammo type boost your weapon’s accuracy and bullet velocity respectively. The June 30 update gave both of these attachments received a 3% reduction in muzzle velocity.

Meanwhile, the M1941 Handstop underbarrel’s recoil control has been changed to 3.5% down from 4%. While this seems like a minor change, it can actually greatly affect your loadout’s effectiveness in combat.

Since the MX Silencer, M1941 Handstop, and Lengthened are all popular choices for multiple weapons, it’s extremely likely that these attachment nerfs are going to greatly impact Warzone players’ loadout builds.

While the update brought various nerfs to different weapons and attachments, it also featured buffs to Vanguard’s Warzone weapons, as the 3-LineKar98k, and Type 99 all received an increase in bullet velocity.

Warzone expert reveals genius trick to instantly get Loadout Drop

Getting a Loadout Drop early is key to surviving Warzone’s early game but there’s a way to get your loadout in a matter of seconds.

Getting your loadout as soon as possible is vital to winning in Call of Duty: Warzone and pro player IceManIsaac has revealed a genius trick to getting your loadout in seconds.

Loadouts are what sets Warzone apart from all of the other battle royale games. Getting your own custom weapon gives a massive advantage over those with ground loot, so getting a Loadout Drop as soon as possible is key to winning.

It can be tough to get your Loadout Drop in the chaos of the early game, but a clever strategy from streamer IceManIsaac can get your team a Loadout Drop and free UAV in seconds.

Grotto POI in Warzone Fortune's Keep map

To instantly get a Loadout Drop in Warzone, all players need to do is land on a Top Secret Contract in Fortune’s Keep. This will starts a random Contract such as Supply Run, Scavenger, or a Bounty, and you’ll get a whopping $8,000 as well as a UAV.

IceManIsaac explained that the Supply Run won’t task you with traveling across the map like in Caldera, it’ll actually be pretty near, so you’ll be able to land on it in a matter of seconds. A loadout only costs $7500 dollars so you can buy the loadout straight away and have a free UAV to see any approaching enemies.

While doable in Solos, this strategy works best in squads. If one player picks up the Contract and the rest float in the air to complete the task, the process will be even quicker. Even if it’s a Bounty, all of the players can land on top of the target and it won’t matter if they die in the process because of the Resurgence mechanic.

Fortune’s Keep is pure chaos in the early game, so securing yourself a loadout before anyone else will be sure to set you up for success.
