Call of Duty: Modern Warfare’s patch on May 19th changed a few key things about Warzone, like weapons in the Gulag, but it also added the ability to finally crack into the bunkers. Here’s how to get into Bunker 11, and what you’ll find there when you do.

Call of Duty: Warzone | How to Unlock MP7 Mud Dauber

This is one of those elaborate multi-stage Easter eggs that would never have been found at all if it was in an even slightly less popular game. The locked-down bunkers found throughout Warzone’s map have been driving people mad with curiosity since the game launched.

When players finally figured out how to open the bunkers, with a Red Access Card, they found a ton of useful loot. In the case of Bunker 11, however, found on the northern edge of the map above the Military Base, they also found another locked door. A couple of players have managed to glitch inside the next room, but it was only yesterday that the Warzone community figured out how to open Bunker 11 properly.

Opening the secret room in Bunker 11 is best done as a team effort, and will be easier with voice chat and in Plunder mode. You must first search the map to find which of seven phones is currently ringing. This changes from match to match. When you answer the phone, you’ll hear someone say three numbers in Russian, followed by three chimes.

Mystery Phone

Location

#1

In the Downtown area, just west of the building marked “Downtown” on the in-game map, there’s a building that’s kind of shaped like a triangle with rounded sides. Go inside it and down a few flights of stairs until you find this phone on a desk.

#2

Inside one of the buildings in Novi Grazna Hills.

#3

Inside a building on the southern end of the Boneyard.

#4

In an office at the BCH TV station.

#5

Look for a blue building north of the Atlas Superstore.

#6

Towards the back of the vacant building in the City of Verdansk Port.

#7

In the control room at the Gora Dam.

Those three numbers–this entire Easter egg is a blatant scheme by Activision to teach an entire generation of players how to count to ten in Russian–correspond to three other phones that are located throughout the Warzone map. Currently, the most efficient way to find the second set of phones seems to be using this helpful infographic on Reddit.

If you interact with each of the phones in the proper order, you’ll hear some beeps to indicate you’ve made progress. After you pick up all three phones and have completed the code, you can move on to Bunker 11. It’s probably useful to do so in force, as the new hotness since this was puzzled out was for lazier players to simply wait in ambush outside Bunker 11 for someone else to open it. Once you’ve managed to get there safely, you should see a green light above the door to indicate it’s now open.

Inside Bunker 11, you’ll find a treasure trove of loot, as well as the legendary MP7 blueprint, the Mud Dauber. If one player on your squad grabs it, it unlocks for everyone at once. There’s also another peculiar Easter egg in here, involving a nuke, that may lead to more hidden loot, or could be a hint at events to come. At this point, I think we’ve all earned the right to get a little anxious/excited whenever a nuke shows up in a Call of Duty game.

Call of Duty: Warzone doesn’t seem to be slowing down. I’m genuinely impressed that the community was able to figure this out at all, let alone this quickly. Keep us informed about any other incidental weirdness you’ve found via our official Twitter, @PrimaGames.
