How to open bunker 11?
Bunker 11 is quite special, because the latter will allow you toobtain the legendary blueprint for the MP7 called "Mud Drauber". If you absolutely want to access it, prepare yourself as it should since it will require a lot of patience and several attempts.First of all, you are going to have to go to the different phone locations that are all over the map, and when you hear one ringing, interact with it. If a dial tone occurs, it means it is not the correct one, but if you hear a message in Russian, this indicates that you are on the right track.
