These bunkers have been present for a long time without the ability to be cracked open, now, if players are lucky enough they'll have access to high-end loot that will give them an edge on the latter stages of the game.
Before we get to looting, however, we must answer:
Where to find the Bunkers in Call of Duty: Warzone
There's a total of 11 bunkers in Warzone, with bunker 11 being the most elusive of the bunch, here are the locations pinpointed on the top-down map.
The marked X at the top, that's bunker 11. Some are almost right next to each other, so prioritizing those areas should make it easier to bump into them.
You'll be able to identify bunker entrances easily. Either they have big bulky doors surrounded by yellow bars shutting them down or small reinforced doors that'll lead you to an underground one.
In order to access them, you'll need a very rare item, a Red Access Card.
How to get Red Access Cards in Warzone
Getting your hands in one a keycard that will grant you access to Warzone bunkers is no easy feat. The most consistent way to get a red access card is via the crates that drop around the map. If you can score a kill on someone in possession of a card, you'll be able to retrieve it and use it for yourself.
It's worth pointing out that once you enter a bunker, you might find another closed door - do not waste your time trying to open this, as they are currently unavailable for players. Dataminers found out about the existence of blue and green access cards, which could be tied to these entrances.
Once inside, players will be able to find high-end loot that could be key to their survival, cash to stock up on even more goodies, and more than enough gear to deck out an entire squad.
Now that you know your way around 10 of the 11 bunkers, it's time to answer what's inside that last one, and why it's so special.
How to open bunker 11 in Warzone
As we've said, bunker 11 is the one you'll find all the way up north in Warzone's map, specifically located to the northwest of Military Base. If you're up for the challenge, here's how to open this particular bunker.
First off, once you start a game, head to these locations marked below, and look up for a telephone, interact with it. If it gives you a dial tone, move on, you're at the wrong one. If you're lucky, however, you'll hear the voice of a Russian Commander that'll give you three numbers.
He speaks in his native language, so be sure to double-check with a translator in case your Russian is rusty...
Once you have the numbers, head out to the phones that match the codes the Commander gave you. You'll hear a morse code that's the same as the numbers you were given, no need to write anything down. After you're done with the phones, head to the bunker and you should be able to get in.
Among the many things you'll find inside the bunker are the blueprints for the powerful Mud Drauber SMG and a nuke being built, which many point out as a tease for a possible event further down the line.
Will you be trying your luck at cracking open one of the bunkers?
