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.

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.

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.
