Automatic rations
Equip a ration icon. When your life reaches zero, the ration will automatically restore part of your life so you do not have to.
Avoiding detection
When a patrolling guard sees you, run into a room where the screen goes black and tells you where you are. The game will not go into alert mode, evasion mode, or caution mode.
If you have an a silenced USP/SOCOM, you can shoot at pipes. They are quite common in the game, and, when hit, shoot out steam. This will paralyze or distract an enemy, depending on their proximity to the pipe. Fire extinguishers have the same effect. With a silenced weapon, you can shoot a wall near a guard to make them turn and look at the wall for a few seconds. If you evade a guard's detection in hanging mode and they walk past, press [Action]. Your character will flip over the railing and knock the guard out with the impact. Alternately, you can fall on a guard from hanging mode. If you are out of ammo, unequip your weapon, run at a guard, and when close, press [Crouch]. Your character will either do a somersault or a cartwheel and the impact will knock the guard out. if all else fails, toss a chaff grenade, run and pop off all the guards before the radios work again.
Bird droppings
Complete the Tanker chapter with Snake. After that, get to the roof with Raiden. You will see a group of birds. Shoot one with the M9. The rest of the birds will fly around. If you see one go directly above your head, it should send some droppings on you. You have to be in first person view. The bird droppings will also come off the screen when you go back to third person view.

Choking enemies
A silent and reliable method for knocking out an enemy is to choke them until they lose consciousness. However, this technique has an extremely high chance of "accidental death" due to the enemy's neck breaking. It takes eleven chokes including the initial grab to eliminate the enemy. Therefore, choking the enemy nine to ten times will result in the enemy being "knocked out".
Codec comments
When playing as Raiden in the Plant chapter, go into strut C after the intermission sequence where Vamp kills the SEALS. Go into the women's bathroom, open a stall, then go into first person view. Look at the toilet. This may require a few times attempts. Call the colonel and he and Rose will be mad at you and Rose will not let you save the game. You can also go into the men's bathroom and call the colonel when looking at the urinal and he will excuse Rose.
When on the Plant chapter, after getting the Stinger Missiles find an area where there are seagulls . Lock on one of them and fire a missile. The colonel and Rose will call you on the Codec with a funny message.
When playing as Snake in the Tanker chapter, knock out an enemy then take a picture of him sleeping. This also works when you are being chased by the big heavy people with shotguns and take a picture of them. After you have the picture and put them into the computer, Otacon will say that this is not a game.
Collecting claymore mines
Get near claymore mines, then get into a prone position over them. The claymores will be placed into your inventory.
Collecting dog tags
Use this trick to collect dog tags from nearly all guards. The only drawback is that it may take some time, depending on where you are in the mission; knocking out all other nearby guards before starting and targeting reporting guards last is recommended. If you cannot get close enough to a guard to demand his dog tags without being spotted, begin by tranquilizing him from a distance. Run to where he falls. Pick him up from the shoulders to make sure he is facing up. Position yourself so that you are standing in line with his head (but not literally on top of him). Also, make sure that when he stands up there is enough room in front of him that you can run around and demand his dog tags. When he starts to get up, equip you M9. The moment he reaches a standing position, hold him up. The guard will not have time to turn around and see your character. To wake up guards faster, use either the Coolant Spray technique outlined elsewhere or prop the guard against a wall (feet first, preferably), enter first person view, and punch at the highest part of his body. Both ways will get them up faster, but make sure you are in a good position to hold them up in case they wake up faster than expected. This technique also works well to salvage failed attempts (i.e. you were spotted, panicked, and tranquilized him, which is a good reason never to have your USP or Socom equipped when first holding someone up as you do not risk panicking and killing the guard by accident.)
Go up behind a person and hold them up (point your gun at their back and saying freeze). Go up in front of them then point your gun at their face (the USP or SOCOM recommended). They will say something like "Don't shoot" or "No". They will shake and the dog tags will fall out. Then, shoot them in the head (optional). If they say "Go ahead and shoot me", shoot either their left hand or directly above their head. They will shake and the dog tags will fall out. If they do not shake after that, they do not carry dog tags.
When you are collecting dog tags and do not know if a guard has one, equip the 'Thermal Goggles'. If he has a dog tag, he will be wearing a necklace with a small metal plate on it. His body is red because it is warm, while the dog tag is blue because it is cold. The best way is to tranquilize the guard then turn him over. When he lays on his belly, and look at the body with the Thermal Goggles.
Coolant defense
When you are bombarded by guards, do not immediately shoot them. Take out the Coolant spray that Stillman gave you at the start of the game. Spray the Coolant at them and they will protect their faces. While they are doing that. Use the opportunity to shoot the guards and run.
Costume and weapon bonuses
Complete all of the Snake Tales twice. Complete 100% of all VR missions. Then, complete the entire game under any difficulty setting. Start a new game with the save file that was completed. You should now have access to Snake's Tuxedo and Metal Gear Solid costumes in the items list. The M4 and AK7 rifle will also be placed somewhere within the Tanker.
Deactivating C4 bombs
When deactivating the "Baby C4 bombs", the last one for the very easy and easy difficulty settings is under the submarine hanging from the ceiling in the bottom of Strut A Shell 1, where you started out as Raiden. The one on the hard difficulty settings always move around the room, usually in the caged area under the stairs or behind the computer controls.
Defeating Solidus
In the final battle with Solidus, before he sheds the tentacles from his suit, you can run off the side of the building and hang on the ledge. Solidus will come over and say "What are you doing?" and go for an overhead double sword strike. When he does this, press the button to climb back up and Solidus's attack will go through you, giving you a free shot at him. This can also be done to avoid his homing missiles, but you have to climb back up at just the right time to avoid all four.
Defeating the Metal Gear RAYS
Use the following strategy under the hard difficulty setting. In the first part, the organization of the machines allows you to win easier if it is done fast. Quickly hit the machine in the middle, then hit the machine in the right corner, followed by the one in the left corner -- always one leg and one head, so that it starts again. Do this three times and on the fourth quickly select which machine you want to fight and hit it. In the second part, run towards to avoid the machine's attack. Stay in the middle to prevent being attacked by homing missiles and getting stomped. If you get in position and can hit it, attack fast but concentrate on the head. The position makes it more difficulty but you have two chances. When the machine near attacks quickly escape from it. If you stay exactly in the front the others, the machines will hardly attack. During the beam attack, quickly avoid it and use the Stinger. To detect the beam, note that the near machine will face your horizontal line and nod before attacking. At that moment, avoid. After the near machine is defeated the two others will usually prepare to approach you. Try to guess your next opponent and take his life down and hit the other consecutively. Note: If you get far from the machines and go back, the near machine will usually launch horizontal homing missiles. Watch what the near machine is doing or wait for its attack to become safe to quickly avoid it. Do not run forward until you are safe or the machine will get you.
Defeating Vamp
As soon as the fight begins, run over to Vamp and get as close as possible to him without falling into the water. Quickly equip the stinger missile launcher and begin to constantly bombard him with missiles. Tap the button as fast as possible to defeat him in about fifteen seconds.
Under the extreme difficulty setting, at the beginning of the battle when Vamp bows, shoot him with the Stinger. You might be able to do this two or three times if you are lucky. As soon as he goes underwater, shoot the lights out quickly before he comes back up. When he first goes underwater, he will come back up after about one sixth of his oxygen is used, unless of course you shoot him while he is underwater (which will deplete his oxygen after a few shots). If you shoot the lights, you will most likely not have enough time to shoot him while he is underwater. Throughout this battle, Vamp will alternate between standing above you while throwing knives at you, and chasing you around on the catwalk trying to slash at you. He always starts the battle by going above you while throwing knives. When Vamp throws knives while above you, wait until he starts throwing them in rapid succession. When he does this, try to anticipate his movements so you will end up directly beneath him once he finishes throwing the knives. As soon as he stops, fire repeatedly with the Stinger. You should be able to hit him about three or four times. When he goes underwater after throwing knives at you from above, place a Claymore mine on the catwalk to the right as you enter the room. Then, stand on the southern-most catwalk in the room as you enter. Stand to the right of the line that is in the middle. When Vamp comes up, he will run directly into the Claymore, causing him to go back under. When Vamp's life bar reaches about one third, he will change his knife throwing pattern. He will throw two knives in rapid succession, then pause for a second or two before throwing a third knife. He will do this three times before going underwater. With this knife throwing pattern, it will be difficult to hit him. You may want to dodge his knives rather than try to attack him during this time. If you do choose to attack him, do so by getting your Stinger ready before he comes up. When he comes up, shoot him immediately when he lands. This can be dangerous because you will be open to attack from his knife-throw if you do not hit him. if you do not attack him, a good strategy to avoid getting hit is to run in circles while moving in a zig-zag pattern. Also, do not let him get close to you with your back to him. If this happens, you are very likely to be hit. Once Vamp's life is down to approximately one tenth, he will change his attack pattern. He will move around very quickly and occasionally throw five or six knives simultaneously. The best way to hit him during this stage is to track him with the Stinger and fire just as he is about to throw knives at you (or any other time when you think you can hit him). This last stage is the toughest; you will have to be very quick not to get hit. Try to make sure you have full rations for this battle (especially the last part).
When the battle starts, shoot Vamp. When he goes into the water, run anywhere near an edge and plant a C4 bomb. Then, jump over the edge directly next to the bomb. When Vamp approaches, he realizes that he cannot hit you and jumps down. He will start to walk toward you, and when he steps over the C4, blow him up. He will jump back in the water. Repeat the cycle until he dies. Note: Act quickly, because if he jumps up before you are done, you will be knifed.
To make the battle with Vamp easier, simply shoot out the four lights positioned around the room. Vamp will no longer be able to freeze your shadow, as you no longer have one.
Run directly up to Vamp and throw a few punches and kicks. After three or four punch/kick combos he will be knocked out.
Digital camera
Successfully complete the game. The digital camera will be available when a new game is started. The digital camera is located in Strut E Shell 1. Go to the bottom of the screen and locate the platform with three red lights on it. Climb up onto it and equip the Z.O.E. Box. When the conveyor stops, press [Action] to climb on. You will be taken to another room. Press [Action] again to get off and retrieve the Digital Camera. Exit the room in the same fashion.
Domino effect with guards
In the holds, stand next to any guard and do the punch, punch, kick combo. They will go flying, knocking down almost half of the guards. Also grab the guards by the projectors and hold them up. Then, do the combo for longer distance.
Easier Pull-ups
Instead of doing half an hour of pull-ups, go to a place with two rails at the top and bottom, evenly lined up. Then, do the hang-drop-catch ten or twenty times to get a fast level 2 and 3 grip.
Easy radio shots
To knock out an enemy's radio easily, when you hold them up shoot it (on the belt to the right of their back). Also shoot an enemy's radio when they are knocked out to prevent them from calling for help if they wake up.
If you shoot at an enemy's radio when he is calling for backup, it will be destroyed and you will have a better chance to kill him. This also works if you throw a Chaff Grenade at a enemy's radio.
Emma and Snake's funny comments
When Emma is walking on the oil fence and Snake is in his sniper position, take your Directional Mic and point it at both of them.

Exploding poster
When walking through the engine room, you will eventually find yourself underneath a Russian guard that is standing on a ledge hanging above you. If you watch his pattern, you will notice that he is using binoculars to look at the wall. Look around the wall behind you. You will notice that he is looking at another one of the pictures of the Japanese girls. While he is looking at it, shoot it with one of your weapons (preferably the silenced USP if available). When you shoot it, it explodes. Note: Doing this sends you into alert mode; be prepared for the backups.
Fire extinguishers
If you shoot a fire extinguisher and are too close, your character will cough and your health will decrease.
Get Hideo Kojima's dog tag
Play the game on extreme mode. When you meet Snake in Arsenal Gear Ascending Colon to get your things back, knock him out. Unequip your weapon, drag him, and he will drop Hideo Kojima's dog tag.
Get Hideo Kojima's picture
In the Tanker chapter in Hold No. 2 where the Marines are located, take a picture of the right screen with the camera that Snake uses to photograph RAY. A face will flash on the screen when you take the picture. If you upload the photo for Otacon's viewing, he will be scared. The face is Hideo Kojima, the creator of the Metal Gear series.
Guard with red eyes
Whenever you kill a guard and shoot his eyes, they normally will not get bloody. However, there is a guard in the Plant chapter where this does not happen. After you have defeated the Harrier you will proceed to a path on the side of one Shell. You should find a guard on the roof that urinates off of it. Use your silenced AK to shoot him down. This is very difficult, but you can have a chance to shoot his head when he speaks about his urge to urinate. If you miss the first time, shoot the wall under him. He will walk to the noise, then return and begin talking again, giving you another chance. When he falls, approach his corpse and shoot his eyes, which still will be open. They will have blood in them.
Hostage comments
In B1 of the Shell 1 core, where all the hostages are found, you can get a good laugh by pointing the directional mic. at every hostage except for Ames and pressing Action. Some will be scared, some will get angry, others will simply turn their head away, and some may have something interesting to say. You will eventually find Jennifer, the secret service agent Snake rescued in the "A Wrongdoing" Snake Tale. It is recommend that you have stealth equipped while tying this, as the more racket you cause the more guards will be called in to patrol the area.
Kissing poster
When playing as Raiden in the big shell, find the Shell One mess hall. Enter the men's restroom. There will be a girlie poster on door of the stall on the left. Get in that stall and close the door. Enter first person mode and zoom in on the poster. Raiden will make a kissing noise.

Take out your tranquilizer and shoot his radio so he cannot use it. Wake him up by spraying him with Coolant. When he wakes up, run and hide somewhere for a few seconds. After that, run in front of him. He will be alerted and try to radio in. After two attempts to radio in, he will run to find another comrade to help.

Take out your gun and shoot him as many times as possible. Then, get a box in strut E, equip it, and call Snake. He will then talk about loving your box.
Select a ration and call Snake. Jack/Raiden will tell snake a secret about Rose.
Go to hostage room in Shell 1 Core and find Jennifer. Note: She does not have a gag. Use your directional microphone two times to ask her. The second time she answers "Stop don't touch me!", because she was violated by guards.
Tranquilize Jennifer her and crawl under a table. Take out your camera, take a picture of her crotch, and save it. Call the Colonel and they will protest.
Plant chapter: Bird talk
Go to B2 of the Shell 1 Core. Eliminate all guards and find the caged parrot. You can teach it to say "You must be Ames" by pointing the Directional Mic at it and pressing Action several times. Firing different weapons at the bird will also cause it to say new things. For example, Coolant Spray will cause the bird to say "This sucks".
When you are in the computer room on B1 of the Shell 1 Core with guards in it, if you shoot the bird, he will say "Enemy spotted, send reinforcements" and the game will enter Alert mode.
Plant chapter: Boxes
In the strut where the boxes are located, you can put on a box and go to the bottom. Once there, you climb on the box delivery port and wait for the conveyer belt to stop. Depending on what box you have on, the belt will take you to where those boxes are supposed to go. For example, the orange boxes will take to the cafeteria.

He picks you up and leaves with Raiden, and Raiden tries to get free. Note: This counts as a mission failure, but is funny to watch.
Snake Tales (External Gazer): Gurlugon kills himself
When playing through Raiden's variety VR missions and you reach Gurlugon, hide behind the tall box on the left closest to Gurlugon. When the box is destroyed, a magazine appears. Gurlugon will go crazy and ends up killing himself. This counts as a success in the VR mission.

You can knock on her leg about six times in a row and the guards will be confused for awhile.
Tanker chapter: Angry characters
Take three pictures of women, three pictures of the Marine Commandant, three pictures of Ocelot (in Hold 3; he is only found if you crawled under the ground), and a picture of two lockers just before Simtex Defusal. Otacon will have some funny responses.
Look at Olga and call Otacon.
Keep pressing the remote about twelve times in Hold 2.
When you pass Simtex and hear "Virazano bridge check point passed", run until you see a guard and press against the right wall. When the guard stops, peek through the corner. The pipe will fall and the guard will not notice you. If you keep still, look at the radar to see a second guard coming. He will save you.
Tanker chapter: Secret passage
In the Holds 2 room, go all the way to the left to find a hatch. Open it, and you will climb down into a small area. Crouch and go through the vent on the ground. You will eventually see a gun clip fall through and a man will start talking. His shadow will be on the ground. Wait there until his shadow leaves, then move through the area. After you get past that, you will reach an opening and an intermission sequence will begin. After it ends, crawl through a vent on the right side of the small room. After you crawl through, you will find a ladder. Climb up the ladder, and it will lead you to a small perch. Look down at the bottom of Metal Gear RAY, and you will see Ocelot standing there. He will then go away. You can keep doing this and experiment with things to do with Ocelot.
Tanker chapter: Snake laughing
While going through the rooms with all the Marines, stop in the second room next to the projectors. Look on the left hand side of the table that they are on. You should find a button there. Face it, and press [Action]. It should switch the screens that the projector is on. Repeat this, and eventually something else will appear on the blank screen. Continue pressing the button until it cuts to a sequence where Snake keeps pressing it. Note: Eventually something will happen and you will be caught and fail.
