The following are cheats for Metal Gear Solid. For a complete walkthrough, click here.
Technical demonstration mode:
Beat the following modes in order - "Training", "Time Trial", "Gun Shooting", "Survival." Note: Completing each mode will unlock the next mode in the sequence. "Technical demonstration" mode will now be unlocked. Use it to watch the CPU demonstrate its best time with the gun.
When you beat the game, if you leave with Otacon, he will give you a prototype of an item called "Stealth." This allows you to walk near, through, and around guards, through trip lasers, and in the field of vision of cameras without alerting. This appears in your inventory when you start your second game.
First you have to get some C-4. Now sneak up behind a soldier and place it on his back. Try not to get to close or he may notice you and shoot you. This is is easier to do if you have the stealth suit. When you do get it on him, he will continue on his regular route. Find a good hiding place that is a safe distance from your intended victim, and press O to detonate.
When you beat the game, if you leave with Meryl, she will give you a prototype of an item called "Bandana." This gives you infinite bullets with any weapons you have. This appears in your inventory when you start your second game.
Beat the game twice and get both endings (one with Meryl and one without). When you play a third time, enter the elevator in the Cargo Dock. You'll remove your scuba gear and change into a tuxedo.
Beat the game twice and get both endings (one with Meryl and one without). When you play a third time, the ninja will be wearing a cool red and black outfit.
Beat the game and get the bandana. When you get the Fa-Mas, shoot all of your bullets except the last 2. Now put on the bandana and you will fire all tracers. You can now aim accurately with the Fa-Mas.
This is a cheat for those who feel they need to see the most ever bared on the Playstation. On the level where you try to save the Darpa chief in the cell, you will meet Meryl, who helps you shoot the intruders after the chief dies. You kill the gunmen and after the cinema sequence go back into the cell where you saw a man naked on the floor. Now get on the ground and take out your scope. You'll notice that the guy's butt is censored, but when you scope in ALL THE WAY you'll notice something the company never thought about. Eeech.
Every second time you play, the initial cut scene when Solid Snake emerges from the water is shown from a different angle. This alternate start is repeated back and forth with the original cut scene from the beginning onward.
Stats when Fighting Liquid:
When fighting hand to hand with Liquid at the end, hit the Circle button on the second controller and it shows the stats of the fight.
I See You Mantis:
When he uses his stealth put on the Thermal Goggles. This way when he uses his stealth you will be able to see where he goes.
Psycho Mantis Memory Reading:
Some of Mantis' reactions depend on the save games of other Konami games you have on your memory card. Try confronting him with a Castlevania, ISS Soccer, Suikoden or Silent Hill save game on your memory card for startling revelations.
After Mantis reads your mind, the screen will go black for a second before the battle begins. To make the fight MUCH easier, simply plug the controller into the "controller two" slot. He won't be able to read your mind anymore and will be easier to kill.
Fighting Mantis, the Alternate Way:
When the Colonel calls you (while you're fighting Psycho Mantis) about switching controller ports, don't do it. He will then call you and tell you to shoot the statues in the corners of the room.
See through Mantis' eyes:
While fighting Mantis, push the first person view button (Triangle). Now you are looking through Mantis' eyes instead of Snake's. This is a useful way to find Mantis while he's invisible.
Easy Metal Gear Rex:
After Ninja has died -When Liquid has turned and is searching for you, equip your PSG-1 (sniper rifle). Get far enough back that you can aim at his head. It will kill him in about 6 shots. Be sure to throw out a chaff grenade. Then run after each shot, or he will see you.
When you blow up all the walls needed to get to the room where you find Revolver Ocelot, go back and get more C-4. When the fight begins run straight to the wall to the left. Place one C-4 ON THE WALL. If it's on the floor too far it will trigger the explosions and kill Baker. Now, chase Revolver around untill he runs right up to the C-4. Detonate. BOOM. Takes off a lot of his power. Repeat this pattern two or three times and he's dead.
The first time you fight this crazy tank-drivin' Alaskan, the easiest way to take him down is to throw a chaff grenade, then run in close. Chuck a "real" grenade at him, then switch back to the chaff grenades, throw it, and do it all over again. Easy and simple.
Easier Raven #2:
Get as far away from him as you possibly can, then take out your Nikita rocket launcher. Shoot and, using your map, sneak up (with the rocket) behind him. When he starts running, just whip out your Claymore mines, and set them in his path. He'll soon be dead.
When fighting the ninja throw a chaff grenade and he will freeze letting you hit him. Once you hit him he falls to his knees and he won't get up until the yellow dust from the chaff grenade has all fallen. Repeat the process till the ninja is dead.
Easier LIquid In the Hind-D:
When fighting the Hind-D on the comm tower, damage the helicopter until it blasts the middle of the tower. After it does that, run to the very edge and corner of the railing and right beside the edge. Here one can get a lot of clear shots at the Hind-D and when the Hind-D fires at you, simply lie down on the ground and watch the bullets fly over you. Whooaaa feel good!
It's a Nikita Ms. Wolf:
When fighting Sniper Wolf in the snowfield, go to the far left where she can't hit you and stay standing. From here you can use the Nikita's guided missiles to take her out. You must send the missiles up over the banks on the side first so that the missiles have enough time to adapt to the ground height. Easy way of killing her.
Pee on the Box!:
Just after trekking through the Caves for the first time, and before you and Meryl enter the Underground Passage to Comm. Tower A, stand facing Meryl with the wolf dogs yapping nearby. Slap Meryl roundly in the face. Meryl whistles and the dogs attack you for such an action. However, if you place a Cardboard Box over you immediately after slapping Meryl, the wolf dog puppy investigates the box. Cocking its leg against the side of it, a stream of wolf dog urine splashes you and the box. You now smell of the wolf dogs, and the hounds now leave you alone on subsequent trips through their lair as long as you're wearing the box they peed on. Sheesh.
But I Don't Want the Wolf to Pee on Me:
Wait until Otacon visits you in your cell after your torture session. He'll give you Sniper Wolf's handkerchief, which, as you'll note, "smells faintly of her". Walk through the wolves' den with the handkerchief equipped, and the wolves will let you past with no hassles at all.
Catching the Flu:
Sneezing every minute can attract guards. Combat this with medicine, but to achieve a sneezing fit every time, fail in Revolver's torture room and come into close contact with Sasaki in order for the cold to be transferred. It helps if you are rescued by the Ninja for maximum exposure to the Sasaki flu.
Meryl in her Undies:
In the Women's restroom where you meet up with Meryl prior to the Psycho Mantis confrontation, follow Meryl straight in and move up to the top stall within five seconds. Meryl will not have time to properly change, and spends the first part of the conversation without her combat pants on. Woohoo.
Meryl in her Undies 2:
When you go into the duct system to save the Darpa chief, look down at Meryl and go back out of the duct system. Then, go back in the duct system and look down at her again and she will be doing sit-ups. Then, go out of the duct system again and go back in. She will be doing leg presses. Go back out of the duct system yet again and the process will repeat. Only now she will be in her panties. Was it really worth it?
When walking around with Meryl, keep staring at her in first-person mode. Meryl starts blushing, turning embarrassed and tapping her gun to her leg. Keep looking at her, and she turns more and more red, whispering embarrassed little questions. How cute.
Cardboard box uses:
Tired of those long walks between the armory and every other part of the game? Well, here's what to do. Once you have a cardboard box, you can ship yourself to different locations from any transport truck in the game. Just get in the truck near the edge, put on your box and wait. Eventually a guard will come by and ship you out.
Cardboard Box A: Get shipped to Heliport, works in Nuke Depot and Snowfield trucks.
Cardboard Box B: Get shipped to Nuke Depot, works in Heliport and Snowfield trucks.
Cardboard Box C: Get shipped to Snowfield, works in Heliport and Nuke Depot trucks.
You're coming With Me:
When you grip a guard by the neck you can open doors with him. Just move him so that he is facing the door and walk into it. The door should open. You have to grip the guard by the neck first.
Shooting crows and rats will make Roy and Naomi upset. They'll contact you through the Codec and tell you how mean you are. Hehe!
The Snide Mei Ling:
If you contact Mei Ling on the codec and after she says "what can I do for you Snake?" you choose DO NOT SAVE and then repeat this about 9-10 times. She sticks her tongue out at you.
Piss-off the Colonel & Naomi:
After Meryl has been shot by sniper wolf and is lying on the ground; try to land a grenade directly on her. If it gets her you will get a message from an enraged Colonel and Naomi!

Talking in Your Sleep:
During gameplay, go up to a soldier while he is sleeping. Stand right in front of the soldier and press the "First Person View" mode button and hold the button
down. Stare at the soldier for a couple of minutes or so. After a while you'll hear the soldier talk in his sleep. He doesn't say much, the only thing the soldier
will say is "WHO'S THAT!?!". This scared the crap out of me the first time I did it. I actually thought he spotted me, but he didn't. He was just sleeping.
Don't Dodge It:
Were you enter the blast furnace for the first time you gotta walk along that ledge while dodging the crane. This part is down right annoying at times. So when you first come in silently kill the guard that's in that area (stealth helps here) then pull out your Stinger missile launcher and blast the crane once. You'll see it stop, lean to one side, and start smoking. You can now go across the ledge without worrying about the crane, but why stop there when you can blast it a second time and watch it fall into the molten metal. Before you fire the second shot, move as close the rail as possible. Now when it falls you can leave your stinger equipped and use it to get a better view of the melting crane.
Let's See If You Can Fly:
You can do something similar to the "Don't Dodge It" hint with guards that are on platforms or raised levels. The stealth is necessary to do this. Equip the stealth device and go up the stairs (the helipad is ideal for practicing this) and put the guard in a choke hold. Position and drop the unconscious guard so that they are laying stretched out next to the rail like this ===. Position yourself at the guard's waist with your back pressed against the rail. As the guard stands up he should be right in front of you. Move toward the guard and press Square at the same time. Snake should grab the guard and flip him over the rail. You'll here a grunt and a thud. When you do run down to were he landed, If you get there fast enough you may find ammo or rations. When you do this in the blast furnace they fall into molten metal and disappear in a hissing cloud of vapor.
Secrets to the Best Ending Rank:
-Resist the urge at all times, to kill a guard. To get the highest ranking you have to kill 0-3 guards. Bosses don't count.
-You also have to play through the whole game without saving... Yup, you heard me.
-The fewer rations you use, the better. 0- 5 is the most you should use, to get the best rank.
-The fewer times you get spotted by the guards the better. Your name is Snake, right?
-The last trick up your sleeve should be speed. If you're sneaking around the cheats page at Game Revolution, you should know your way around the game by now. Since you know what will happen and when, be one step ahead of the game.
