How to Open Submarine Doors in MW2 Atomgrad Raid

Modern Warfare 2 Atomgrad Raid Code Open Submarine Doors

Since Raids are co-op, there is no surprise that the three players have to work together for this. Once the code system for the Modern Warfare 2 Atomgrad Raid appears, you will understand the requirement for communication. You will have three machines in the room through which you have to decode a 9-digit code of three 3-digit sequences.

While it won’t be quite that difficult, your teamwork will adjudge how long it will take to get this done. The steps below will show you how to open Submarine Doors in MW2 Atomgrad Raid:

  • Firstly, one of you will have to press the red button so one of the players can go to the other room. The one who goes on the other side will have to access the Surveillance System and look through the camera for the numbers.
  • Now before you do anything, we will explain the three machines that will help you decode the MW2 Atomgrad Raid Code easily. Since you are looking to open the Submarine Doors in Modern Warfare 2, this is the most important part.
    • Russian Alphabet Machine – This is the red one you can find in the room. The three alphabets will represent numbers that can be decoded with the Surveillance System. There might be extra alphabets on it to act as decoys but they shouldn’t affect you that much.
    • Surveillance System – Once you use the Surveillance system, you will be able to use the camera and see the alphabet on the walls with numbers. These numbers represent the three-digit code and with the first machine, all that is left is to input the code.
    • Code Machine – Use this to input the code that you derive from the first two machines. Make sure that you keep rotating the role as each player must input one three-digit sequence.
  • Now that you understand the machine well, it shouldn’t take that long for you to decode the MW2 Atomgrad Raid Code.
  • As we mentioned, make sure that you rotate the roles and look out for the decoys. For instance, you might see five alphabets, but a couple of them won’t show up as numbers on the wall. That will help you rid out the decoys. If there are four alphabets with numbers on the wall, the first three seem to form the raid code sequence.

That’s all there is on how to open the Submarine Doors in MW2 Atomgrad Raid. While you are here, make sure you check out other Modern Warfare 2 guides right here at Gamer Tweak.
