Codec Contacts & Frequencies

Your Codec is an indispensable tool for navigating Shadow Moses Island and uncovering its secrets. Maintaining regular contact with your support team and knowing the right frequencies for crucial information can mean the difference between mission success and failure. Always keep an eye out for new frequencies, as they often unlock vital hints, story progression, or even hidden gameplay mechanics.

Activating Your Codec

To use your Codec, simply press the START button to open your inventory, then select the CODEC option. From there, you can cycle through your known contacts using the D-pad or analog stick. To input a new frequency, select the "Frequency Input" option and enter the digits. Remember, some frequencies are only active at specific points in the story or after certain events have transpired.

Finding Hidden Frequencies

Some frequencies are not immediately obvious and require exploration or keen observation to discover:

  • The DARPA Chief's Frequency: After the DARPA Chief's unfortunate demise, inspect his body thoroughly. The frequency for the next objective will be subtly revealed.
  • Baker's Frequency: Similarly, after encountering Kenneth Baker, pay close attention to the environment around him. A crucial frequency for advancing the plot will be found nearby.
  • The Wolf's Frequency: During your encounter with Sniper Wolf, listen carefully to the ambient sounds and dialogue. A specific frequency will be mentioned that can be used to contact her, though the outcome of such a call is... unique.
  • The "Ghost" Frequency: There are rumors of a very specific, obscure frequency that can be found by listening to the environment in certain areas, particularly those with high electromagnetic interference. Experiment with frequencies around 140.00-142.00 in areas like the Communications Tower or the Snowfield for a potential surprise. This often requires a keen ear and patience.

Always remember to check your Codec regularly, especially after major events or when you feel stuck. Your team is there to help, and their advice is often the key to overcoming the challenges of Shadow Moses Island.
