The Friendly Fire trophy/achievement in Metal Gear Solid 3: Delta – Snake Eater is a fun little secret you can unlock by making enemy soldiers accidentally give you the fire support radio frequency. Once you have the code, you can use your radio to call in an airstrike. The trophy can be earned in multiple areas, and it only works after you’ve actually interrogated a guard to get the frequency. This guide will show you how to do it step by step, along with a full list of all fire support frequencies in the game.
Friendly Fire Trophy Guide / Achievement Guide
You can earn this trophy in several areas, but the earliest place to do it is Bolshaya Past South. Here’s what you need to do:
- Sneak up quietly behind a guard by holding L1 to move silently.
- When you’re right behind them, hold R2 to grab them using CQC, but don’t push the left stick, or you will accidentally slam them.
- While holding them, press L3 a few times to interrogate them. One of the guards will eventually tell you the fire support radio frequency for that area.
Keep trying this on different guards in the same area until one gives you the code. Once you get the frequency, use your radio to call it; this will unlock the trophy. The frequency will only work after you get it from interrogating a guard. If you try to use it beforehand, it won’t work.
All Fire Support Frequencies in MGS Delta: Snake Eater
You can use these frequencies to call in air support, but only at certain outdoor spots. The codes are different depending on your difficulty, and you will need to interrogate a soldier first to actually get them. The first time you pull it off, you will even unlock a trophy.
