Easter Egg: Motion Capture Actors
During a cut scene, if you see the name of the character, the name in the parentheses is the voice actor. If you hit O, the name will change to the name of the character's motion capture actor.

See ghostly images of the developers during the fight with the Sorrow.

Using the camera, take pictures of the bosses you've killed as they walk towards you as ghosts. Sometimes you'll see the faces of the developers on the pictures you've taken.

Title Screen Change
After beating the game once, Snake will have an eyepatch on during the CQC fights he has with the Russian guard at the title screen.

Glitch: No Damage Through Torture
Hold [L2] during the entire torture sequence to not recieve any damage when Volgin punches you. It must remain held down until cutscene where he leaves otherwise any damage that would have been done is still dealt.

Dazing a Guard
Whenever the '!' or '?' icon appears above an enemy's head, and you shoot it, (this is tricky) the the guard appear to be intoxicated and have some white bubbles floating from his head, giving you a few seconds to either run away, or to attack the dazed guard.

Distract Voligin
Before you fight Volgin be sure to capture a living tree frog. When you are fighting him equip the tree frog as a weapon and throw it somewhere where volgin will see it. After he sees it he should say something then jump back he will then be vulnerable for a few seconds(until he kills the frog) allowing you time to get a few cheap shots in.

Find Secret Codec Frequency to Call Off Alerts
If you enter alert mode, capture any nearby guard and interrogate him. Sometimes, the guard will tell you a Codec frequency that can be contacted to call off the alert. These frequencies change after they are first used, but there will always be a new one available whenever you trigger alert mode.

Free Rations/Ammo in Original Metal Gear
If you die and choose "continue" too many times (approx 5- 10), you'll be given max ammo (only for weapons you have obtained) and full rations. Your maximum capacity for weapons and rations increases as your rank increases, which you increase by finding hostages.

Anger Volgin
When fighting Volgin the first time you can wear the Ivan's(Raiden's) mask and he will think you are the major and hesitate from attacking you. You will have a chance to shoot him a few times without him attacking. He will realize who you are after a while and become angry and attack more frequently.

Secret Gametype for Online: HEAD SHOTS
When making a room online type HEAD SHOTS as the title of the room to play a secret gametype. In this gametype you must get headshots on your opponents or your character will blow up.

Snake's dream
When Snake gets puts in the jail cell. Save the game and turn the system off. Turn it back on and go to your saved game file. Load it and you will see a mini-game were you are this Zombie hunter guy and you can go around and kill zombies.

Volgin's lightning
When fighting Col. Volgin throw a Russian glow cap and it will absorb his lightning attacks for a little bit.
