For months fans have wondered what is behind the bunker doors in Call of Duty: Warzone. And with the big May 19 update for Modern Warfare and Warzone, fans have finally been able to unravel the secrets. Among loads of cash, killstreaks and weapons to loot, and unclassified intel to uncover, something that most fans didn't expect is deep inside one of the bunkers: a brand new blueprint.

Blueprints are usually unlocked via battle pass progress or through in-game store purchases. Hiding a blueprint in-game for players to find and unlock is certainly a new twist, and a welcome one. Now that the secret has been discovered, players all over will want to jump on the opportunity to snag this MP7 blueprint.

The MP7 Mud Dauber blueprint can only be unlocked Warzone and by opening up Bunker 11. It won't be easy, however, as surviving the onslaught of human enemies is also something that players will need to do.

How to Unlock MP7 Mud Dauber SMG and Open Bunker 11 in Warzone

To get the MP7 Mud Dauber blueprint, players will need to open up bunker 11 in Warzone and follow the specific set of easter egg-like instructions to do so. The guide for opening up bunker 11 points out the exact location as to where phones are, the bunker is, and more (which are all needed for the MP7 blueprint).

There are seven telephones scattered throughout the Verdansk Warzone map, and these phones will be ringing. Once a phone is picked up, a Russian voice can be heard saying any three numbers from one through ten. It will be important to jot down the numbers because players will then need to visit additional phone locations in the correct order throughout the Verdansk Warzone map. Once each phone has been interacted with in the correct order, a chime and more Russian dialogue can be heard, signifying bunker 11 can be opened.

Some fans on Reddit and social media have noted that the MP7 blueprint may be bugged, as people have reported that they are having issues with unlocking the item even after following the instructions and picking it up in-game. Additionally, some Modern Warfare and Warzone servers are done right now, adding to the confusion.

Still, once the dust settles on any server or bug issues, the blueprint being inside of the bunker is certainly pretty cool. Additionally, the bunker holds more secrets like a gigantic nuke that might make way for a new Warzone map. All of the bunker's secrets may not have even yet been discovered.

For now, the prize of bunker 11 is certainly the Mud Dauber blueprint. The MP7 is one of the best guns for Warzone, so it's awesome being able to laser enemies with a new variant of the SMG thanks to a new easter egg.

Call of Duty: Warzone is currently available on PC, PS4, and Xbox One.
