How to crack the code on black ops

The Numbers Station Broadcast is a bit trickier, as it comes in the form of an audio reel tape. You'll find this during Brick in the Wall — once you get to the part in the mission that brings you to the prisoner, you should be able to find it laying nearby.

The front page of the Observer can be found in Redlight, Greenlight in the retro bar. It's the last piece of evidence you need before trying your hand at decrypting the floppy disk. This will pull up a prompt that asks you to enter a code and a passphrase for the inserted floppy disk. Unfortunately, the codes appear to be different for each player, so you'll need to do a bit of legwork on your own. First, examine the Coded Message you picked up earlier. It should include a bunch of red and blue numbers and letters.

It's your job to figure out what the missing numbers are in each string — examine the red numbers, find a pattern, and solve for the missing digit. Then do the same with the blue ones. Ignore the letters and symbols — they're only there to throw you off.

Next, check out the Numbers Station Broadcast and look for the two numbers you just found in the Coded Message. These numbers will correspond to a city — which will be used as your passphase for decrypting the floppy disk. The final step is to glance at the Observer paper. Some of the letters on the front page are written in red. To begin solving the puzzle, examine A Coded Message. Some numbers will appear and leave two question marks that you need to fill in.

The red numbers and blue numbers follow a set pattern, and you have to use this pattern to deduce what the missing numbers are. Everyone has different numbers and patterns , so you will need to do some math on your end. In my case, the red numbers added 6 every time, moving from 28 to 34 to 40 and so on.

The blue numbers increased by a larger number each time, adding 1 to the first number, 2 to the second number, 3 to the third number, and so on. Keep in mind, the patterns and numbers will be slightly different on your end. With that four-digit code in hand, examine the Numbers Station Broadcast.

Find which city corresponds with your numbers. This is the passphrase the computer will ask you for later. Next, examine the Front Page of the Observer. The headline will have a random group of letters highlighted in red.
