Metal Gear Solid 3: Snake Eater HD Edition Cheats

Fire Support
At any time during game play, on the second part, Snake Eater, go to your codec menu and tune to station 140.73, and call it. This will call in fire support but you will not be allowed to do this more than once. Because the station will not be used again. Believe me, I saved my game, then used it just to play around and then shut it off. Then I went to use it again later and it wouldn't work. So, do not use this unless in dire need.
