Metal Gear Solid 2: Sons of Liberty Cheats

On the title menu hit L2 and the screen flashes now.

Take a cardboard box to Strut E: Parcel Room. Get in the box, and jump onto the conveyor belt, in the top right-hand corner of the room. You will be transported to a different area, based on the box you used. Try them all, and see where you go!

When Vamp's health gets low, he begins to periodically unleash a shadow attack that will prevent you from being able to move; however, if you shoot out the four lights in the room, Vamp will be unable to use the attack.

Do 100 pull-ups while hanging from a ledge (press the R2 and L2 buttons to do a pull-up) and your grip strength meter will increase.

After Snake Gives you the High Frequency Blade and Equipment, knock him out and shake him to get his dogtag.

If you shot enough seagulls with any gun, they'll come and either crap on you or come right up and peck you! Similer to the chickens in Zelda.

As you wait for snake in the Arsenal Gear corridor, a video will start playing on your radar- DO NOT answer your codec to see the whole video.

During the Ames search mission, the hostages change depending on the time Raiden meets Ninja after the Fatman battle and the internal clock of the PS2 console.
0:00AM ~ 0:59AM -> all Jennifer
1:00PM ~ 1:59PM -> all old man
10:00PM ~ 10:59PM -> all old lady

At the first node you log into in the Plant Episode, you're given a chance to input your name, birthday, bloodtype and nationality. If your birthday matches with the same date thats set in your PS2 (most likely you set it to the correct day) you'll be greeted by a Happy Birthday logo with a matching Birthday cake.

During the tanker mission, while the timer is running, you can temporarily stop it by knocking out one of the two guards running the cameras on the platforms in Hold No. 3.

If you don't have the mine dector, but would like to cross a minefield with receiving damage, just go over to the area where you believe mines are and crawl over the area. Not only will you be unharmed, but you'll also obtain any claymore mines that you crawl over!

use the BINOCULARS to identify the names of the person on the dog tag.the name will appear above the enemy.

When a guard spots you, either an '!' or '?' will appear above his head, depending on the distance between you and him. If you shoot this before it dissappears (It's really tricky), the the guard will become dazed for a while and some white bubbles float around his head, giving you a chance to run.

When first playing as Raiden in the plant chapter, enter the name Yoji Shinkawa into the first node. It will automatically put in all of his statistics.

You remember Raven from MGS. well in tanker when you first enter you see a shadow of Raven but you find its just a toy. shoot the toy and it will fire balls at you.

If you get the shaver at the beginning of the plant chapter (by jumping over the rail and going into the enclosed area with the space suit within) you will give it to pliskin when you first meet him. Doing this will have Snake clean shaven at the end of the game. This is vice versa as well if you want a "rugged" Snake do not pick up the shaver!

Enter Hold 1 or 2 on the ship (right after the first boss fight...the Hold rooms are where the Marines are listening to the Commander give his speech). Once inside of either one of the first 2 Hold rooms, creep past the Marines, and look back at them from the north end of the room, so you can see their faces. In each Hold room (or at least one of them), you should spot a few Marines without any pants on (don't worry, they still have some white boxer shorts, though).

Not really a trick, but a cool Easter Egg nonetheless. =)

In the shell 1 core, go to B2. In the main computer area, there are posters of previous Metal Gear games and other games by Hideo Kojima.

At the clear code screen, quickly press Up, up, down, down, left, right, left, right, X, O. You will then hear Snake yell to confirm the code. It does nothing, it's just funny.

When first playing as Raiden, enter the name ''Hideo Kojima'' into the first node. It will automatically put in Hideo Kojima's blood type, birthday, sex, and nationality.

You can do pull-ups a lot faster by doing a drop catch. A drop catch is when you are hanging from a ledge, and then drop down, catching the ledge below. A drop catch is a total of 10 pull-ups!

All you have to do is move the right analog stick and the background will move in the direction that the analog stick was moved. It also will change the color of the background. It is useless but it is fun.

In Tanker Hold #2, press the button by the projector in the back to change the screen that the image is on. Do it enough and a picture of a woman will appear.

While in the Computer Room, look at the walls in First Person mode. You'll see the photo of Charlie's Angels that happened to appear on the cover of FHM magazine.

While watching any Codec conversation, move the left & right analog sticks and the character's faces will move. Press on one of the sticks, and the faces will zoom in close. Press the R1 or R2 button while Snake or Raiden is listening to someone, and you can hear their thoughts! Some of the guys' secret attitudes toward the other characters are quite funny!

During a cut-scene, you can press R1 to zoom in, and use the right analog stick to move the camera around.

Beat the game once and the Extreme difficulty level will be unlocked.

Beat the game and load the same game. you should have the camera in your inventory

Beat the game once and the title screen will change.
