Get the Infinite Bandana
To get Snake's infinite bandana get all the the dog tags in the tank chapter. To get dog tags you must first go up to a guard and stick your gun behind him. Then point the gun at the guard and you will say "freeze". Dont shoot the guard hold square and point the gun at his head or near his private area. The guard will say "dont shoot" or "dont kill me". Wait till you see the dog tag fall on the floor and put him to sleep or kill him. Some guards when you point a gun at them they will say "are you going to shoot me". This is when you need a usp.Shoot the guards leg then point you usp to his face and the guard will drop his dog tag. (supplied by: KrashG007)

Hear yourself
When you are talking to anybody press R2 and L2 then you will hear yourself talking back too.

To stick up a guard
Sneek up behind a sentry and point your weapon at him. (If you have stealth, you can just wait til he walks up to you) Snake/Riaden will say "Freeze!". Then lower your weapon and walk in front of them. Make sure you have your weapon out or they will attack you when they see it isn't out. Point your gun at either they're head or groin. The first thing they will drop is their dog tags. If you already have that person's dog tags they will drop ammo, rations, ect. If they get tough and say "Are you going to shoot me?" or "Who are you??", shoot your socom or usp at the ground or in their leg or arm. Then they'll cooperate! Be careful, though, if another sentry is nearby, they'll hear it and both of them will shoot at you!

Dirty Cheat
When you first enter the interior of the tanker, go right. You should see a door on the right side of the hallway. This is a locker room. If you open some lockers, you can see some pin-ups of some hot japanese chicks. Make Solid Snake crouch, then press against the locker and tap on the girls crotch. Then a little exclamation point should pop up above Snake's crotch!
