"Call of Duty: Black Ops 2 – Zombies": Decode the Cipher (Easter Egg Step)

Outside of my day job as a project manager for a construction company, I am an avid gamer with a great passion for "Call of Duty."

When completing the Easter Egg in Buried, there is a step where symbols appear on the second floor of the Gunsmith. In order to complete this step, you will need to determine what three signs to punch with the GalvaKnuckles.

The easiest way to decipher this code is to look for common letters in each word. I am going to give a detailed explanation below, but first I will give a quick overview.


  • Use the second letter of each line as the key.
  • Find the first symbol that matches the key.
  • Determine the location of that symbol.
  • Use the table or list to determine the sign.

The Cipher

You will find a Cipher similar to the one illustrated below. Each line consists of 17 symbols. Each symbol represents a letter in the alphabet or a space. Decoding a cipher can be complicated without the key. However, we know each line has to match one of the five signs in the tunnel.


The Five Tunnel Signs

You will find the following signs in the tunnels. Each is 17 characters long if you count the spaces as a character.

The Signs:


Matching Symbols

The easiest way to decode the cipher is to look for matching letters in each sign. If the letters match, then the symbols on the cipher will match.

Table 1 (below) breaks the words down by character. As you can see, each sign has a letter that matches the second letter of that sign. This makes decoding quick since you will only need to remember the location of the matching letter.

Table 1

Table 1

Look at one line at a time. The line below is the first line.

Figure 1.1 - The Key

Figure 1.1 - The Key

The second symbol in that line will be the key. Look for the first letter that matches the key. Counting the spaces, what is the position of that number. Figure 1.2 (below) shows the line with both the key and the matching symbol underlined in red. The first symbol to match the key is in the 12th position. From Table 1 (above), we can see that the sign with the matching letter in the 12th position is Ground Biter Pits.

To simplify this a bit more, let's look at a list of the signs with the position marked. This is all you will need as a reference when actually playing the game.

Signs by position of the first matching letter:

Example of Matching the Symbols

Looking at figure 2.1 (above) we can see all three lines with both the key and the matching symbol underlined in red. Now we just need to count the position of the match.

Position of the match:

  • Line 1 - 12
  • Line 2 - 8
  • Line 3 - 6

Using the list above:

  • Line 1 - Ground Biter Pits
  • Line 2 - Lunger Undermines
  • Line 3 - Bone Orchard Vein

Me and my buddies are doing all the Easter eggs and I always make detailed guides to help me Rene the steps, and I have had trouble finding the 5 names of the signs. Your guide is literally the only one with the names listed!! Thanks

Easiest way to decipher the code. Draw a tic-tac-toe sign, pound, or hashtag (whatever you know it by). Put three line in each section (the red lines on the cypher). Then lable each line starting in the upper left corner A through Z. Z will be in the lower right corner. It will be the center mark and the last mark in that section will be a space. I hope this helps

is the code the same every time?

How would you be able to figure this out just playing the game?? So dumb and unnecessarily complicated.

How do u decipher the code

You can literally just look at the first letter in each. You don't need any of this nonsense.

Thanks Pooky

Pooky on July 19, 2013:

This actually makes sense. Thanks. Saved me a headache.

It looks complicated, but using it I am able to figure out the code in seconds.

This is insane...
