In the jungle of Metal Gear Solid Delta: Snake Eater, survival requires more than just mastering CQC and camouflage. The codec, an essential tool for communicating with your support team, holds a powerful secret: hidden radio frequencies that can turn the tide of a mission. These frequencies, a beloved feature from the original game, make a triumphant return with the same iconic functions.This guide will provide a comprehensive list of all known secret radio frequencies, detailing their effects and how to use them effectively in your mission.

MGS Delta Snake Eater: All Secret Radio Frequencies

How Secret Frequencies Work

The secret frequencies are not given to you for free. To unlock them, you must get close to enemy guards and interrogate them. If you've never heard the frequency from a guard, Snake will get "no response" when you try to use it. Once a frequency is successfully used, the game will permanently record it in your radio menu for all future playthroughs.

Healing Radio Frequencies

These frequencies play soothing music that will restore your stamina, which in turn replenishes your health. Each song can only be used once per playthrough. Interestingly, listening to each song for the first time also provides a small permanent boost to your max health.

Fire Support Radio Frequencies

These frequencies will call in an airstrike on a specific location, but only after you have interrogated a guard in that area to learn the frequency. Airstrikes can be incredibly useful for clearing out enemy encampments.

Clear Alert Radio Frequencies

These frequencies are a lifesaver, as they can be used to cancel an alert phase and return the enemy to a normal state. However, they can only be used during an Evasion or Caution phase, not while you are in a full-blown Alert.
