Groznyj Grad Weapons Lab Door Frequency

The western door in Groznyj Grad Weapons Lab: East Wing 1F in Metal Gear Solid Delta Snake Eater (MGS3 Remake) opens with a specific frequency depending on the difficulty. Read on to learn the locked door frequency, the rewards you get inside, and alternate ways to enter the armory.

List of Contents

Groznyj Grad Door Frequency

Door Frequency is 145.86 on Normal Difficulty

The Groznyj Grad armory door frequency is 145.86 on Normal Difficulty. However, do note that it won't work until after you get tortured and return to the base. Also, there are easier ways to enter this room in all difficulties without having to use the radio frequency.

Enter Early Using Officer or Scientist Uniforms

Enter Using Special Uniforms
Mask Mask
Officer Officer 		You can get the Officer disguise after knocking out Raikov. Once you have it, wear it along with the Mask and you should be able to enter without needing a door frequency.
No Paint No Paint
Scientist Scientist
Wait for one of the 1F guards to go near the door. Once it opens, simply walk or follow the guard inside to get the armory loot. You can exit normally, after.

There are two ways to get into the officer-only room in Groznyj Grad without using the door frequency. You can either wear Raikov's Officer Uniform and Mask to simply walk in, or wear the Scientist Uniform and follow behind a guard.

Other Locked Doors Open with the Scientist Uniform

As for the rest of the locked doors in Groznyj Grad Weapons Lab: East Wing, they'll unlock automatically as long as you're wearing the Scientist uniform. Minimize the risk of triggering an alert by simply wearing this disguise if you want to get the loot in each of these rooms.

How to Get the Door Frequency

Get the Call from EVA

EVA Key Frequency Call

The western door on the first floor of the Groznyj Grad Weapons Lab: East Wing can only be opened with a key frequency known to the soldiers. To get the code, you must first approach the door of this officer-only room. This will trigger a radio call from Eva, who will explain the details.

Interrogate a Guard in the Weapons Lab

To obtain the frequency from the guards, you will need to interrogate one of them in the area. You can interrogate an enemy by grabbing them with CQC and then pressing the Interrogate button.

How to Interrogate Enemies
