Call of Duty Warzone bunker locations


The map above shows all 11 Warzone bunker locations. The 10 red circles indicate the “normal” bunkers, in that you simply need a red access card to get inside. As for the blue circle at the top of the map, that’s the bunker 11 location. It’s north-west of Military Base and to get inside there, you need to solve the bunker 11 puzzle which we’ve explained further on.

Inside the Warzone bunkers you’ll find a plethora of top tier loot, all the cash in the world so you can buy extras from buy stations, and all the gear to kit out your full squad. If you can get your hands on a red keycard then you’re in a very good place for the rest of the match.

How to open Warzone bunker doors


First up are the 10 Warzone bunker doors that aren’t related to the bunker 11 puzzle. These are fairly simple to get inside the first level. You need to first get yourself one of the Warzone red access keycards. 

Warzone red keycard locations

There’s no easy answer here as you obtain the Warzone red keycards as a random drop from crates scattered throughout the map. Once you’ve got yourself one though, you can approach one of the 10 bunker doors on the map and open it. You’ll know it can be opened if there’s a green light. Inside these bunkers you’ll find lots of great loot that can help you win the match.

Warzone Bunker 11

Warzone Bunker 11 is an entirely different prospect compared to the others in the game. Opening that involves visiting different phones on the map, collecting Russian numbers and Morse code before you can game access to Warzone bunker 11. It’s less about the loot – although you will find loads of loot and an SMG blueprint – and more about the secret nuke you can find hidden there. Whether players will ever be able to launch it remains to be seen but for now here’s how to open Warzone bunker 11 and get at what’s behind that door.

Call of Duty Warzone bunker message phone locations


So you If you want to get into Warzone bunker 11 then you’ll first have to work out what to do with the phones. The map shows the location of five different phones – these are specific Warzone phones that can play the initial message you need to hear to kick off the first step. You can’t just use any old phone. 

The second you hit the ground you’ll need to head to these these phones and check them. If you hear a dial tone it’s the wrong phone, if you hear Russian talking… bingo! You’re found the right phone and need to listen for three numbers in Russian. The numbers start when you hear a short jingle, and are over when you hear that jingle again.

This is the main crib sheet people have been using to work out the numbers: 


When you’ve heard and deciphered the three numbers, it’s time to move on to the next step.

Call of Duty Warzone morse code phones


For the next step, you need to head to three Warzone phones throughout the map that correspond to the numbers you just heard. The map above shows all 10 phones (0-9), so simply head to the three numbers you heard in order. It has to be in the correct order, or the puzzle will reset.

When you interact with these phones, you’ll hear some morse code. This translates to the numbers you heard before, so if you’re following this guide, you don’t need to bring up a morse code translator. Once you’ve been to all three phones, head over to bunker 11 at the top of the map  marked with the blue circle on the map above.

As you approach, the light should be green, and you’ll be able to interact with the keypad by the door and open it. Head inside and you’ll be rewarded with so much loot, including the Mud Drauber SMG blueprint which will be added to your account.

In one room is a dual-screen computer on the wall, glitching out. Interact with it to reboot it and a timer will start in the next room along, counting down from 10 seconds. When it reaches 2, it will bug out and restart the countdown.

On the opposite side of the bunker, you can crawl through a hole in the wall to find a “Shiny Red Button”. Press it and the smoke will be cleared in the window, revealing a nuke being built. IF it ever does… anything, we’ll let you know.
