Warzone 2 black site keys are special items that let you unlock, you guessed it, black sites. These are effectively an even-deadlier version of the enemy strongholds you can find dotted around Al Mazrah, but if you've played DMZ and used a stronghold keycard to raid an enemy base, you'll know that an item is usually required to access locations with good loot.

It's been a bumpy launch for Call of Duty: Warzone 2 so far, with some players being unable to invite friends (opens in new tab), and other bugs making players die instantly (opens in new tab), but the new DMZ mode is great and even has its own gun that can only be unlocked by playing (opens in new tab). That said, here's how to get Warzone 2 black site keys so you can assault enemy bases to get a weapon blueprint. 

Warzone 2 black site keys: Where to find them 

To get your hands on a black site key you need to raid an enemy stronghold with your squad in Battle Royale. Like their namesakes in DMZ, these bases are filled with elite enemies that you'll need to dispatch, though you'll also have to disarm the bomb that's contained in each. If you're the first squad to clear the stronghold, you'll get a black site key and your loadout. It's important to note that strongholds won't be available until the circle's first collapse, which is when they'll appear on the map. Each of them is displayed with a castle symbol.

Now you've got your key, you can head to a black site, marked with a kind of 3D building symbol with a key in the centre. Since they are locked to those without the key, you're unlikely to run into other players, but you will have to face off against a fair few armored enemies, including a minigun-equipped juggernaut. Take them down, and you'll get a bevy of goodies like a minigun, armor vests, and an Advanced UAV.

What the game doesn't tell you is that completing a black site also unlocks an exclusive weapon blueprint: the Phantom's Call. This is a black, white, and gold rendition of the Vaznev-9K SMG. Curiously, the Phantom's Call also has a number etched on its side that may or may not be connected to an easter egg (opens in new tab).
