Alright, major corrections! When you beat the game with Otacon surviving, he will give you the Stealth Camoflauge at the end, and when you save and load the new game, you will have it in your items menu. But if you beat the game with Meryl survivng, I think she will give you the bandana, but you save a new game and load it and it will be in your items menu at the start! The bandana is a thing that when you have equiped, any weapon will have unlimited ammo, ONLY WHEN YOU HAVE IT EQUIPED! And when you beat the game twice, you will get a tuxedo when Snake goes up the elevator and takes all his equipment off. You will also see the Red Ninja in the third game. CORRECTIONS were told by Forest Ivey and TRUSTNO176.
This is a rumor, and maybe not done yet(for me anyway). Beat the game three times in a row, only saving between games, not being found once, using no rations, complete it under three hours, and you will get the rating "BIG BOSS"! This is only a rumor though, not done. If you have done it, please e-mail me!
CAMERA:
Right before you fight Revolver Ocelot, you need to use C-4 to blow up a hidden wall to get into the room where you fight him. At the end of the tunnel, if you look closely, you will see another door that has been cemented over. Like the others you can use C-4 to blow it up and go inside. Inside, there are: two gun-cameras, a ration, a case of C-4, and two doors. One of the doors is security level six and the other one is level four. Behind the level four door is a small room with a few gun-cameras and a box containing a camera. The camera works just like the binoculars, and use the square button to take pictures. When you take a picture, you can save it to your memory card. The downside is it takes up two blocks. It isn't really a cheat, but it is fun to have.
CARGO TRUCKS:
There are three of them in the game, (One at the Heliport, one in the Warhead Storage Building, and one in the Snow field where you fight Sniper Wolf) if you climb into the back of anyone of them and cover yourself with a box, the truck will take you to where ever the box says to go. You can do this as many times as you want. It is a fast way to get around the base without fighting more enemies. It won't work if the box reads the name of the place you are already in. (I.E using the Heliport box at the Heliport) (Note: Don't worry if there are no enemies around, it will still work You need to be sure that the box is in plain sight, not hidden. Be still for a few moments for the trick to work.)
