Tanker chapter: USP Suppresser
After completing the game once and saving it, start a new game with the saved 
data. On the Navigation Deck after the battle with Olga, go up the ladder to where 
you would normally get the Thermal Goggles. On the middle platform, before the 
goggles, should be a USP Suppresser on the left. You can now equip the USP with 
it and muzzle the gunfire for the rest of the Tanker chapter. 
After you complete the Tanker chapter three or four times, you can find the USP 
Suppresser on the navigational deck after you defeat Olga. It is located on the 
second floor on the lookout, near where the thermal goggles are found.


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: Vulcan Raven action figure
Immediately when you enter the engine room, there is a small Vulcan Raven 
figure standing on the ground with a flashlight shining on it. If you shoot it, it will 
start shooting very small balls around and will repeatedly say "Raven!", or 
something similar.

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.


Beating Gurgolon
To beat Gurgolon use your stinger to hit one of his targets. Afterwards, pull out an 
AK74-U and shoot the little blue thing swarming around where you shot him. The 
target will get smaller making it more difficult to hit.Eventually you will destroy the 
target, repeat until all targets are destroyed. Also theres a funny bit to the level: 
put on the BDU (enemy outfit) and equip the AK47-U. Let him trap you with his 
soundwaves and let him fire his eyebeams.Before it hits you, an explanation point 
pops above his head, which changes into a heart. He picks Raiden up and walks off 
with him as love music plays. Unfortunately you fail the mission.

Make Rose annoyed :
At the beginning of raiden's chapter, when you are first looking for peter stillman, 
if you go into the women's bathroom and into one of the toilets, stay there for 
about 5 minutes not doing anything, if you have nothing equpied, call campbell on 
the codec, he will say something then rose will get angry, after this try calling rose 
and after a bit of speech you will see some funny choices. It's pointless but it's still 
funny!


Skipping codec in a fast way:
If you get a message on the codec and it opens automaticly you can skip it very 
fast. Just push in the four buttons (triangle+ circle + X + square) and you will see 
how fast you can play again, instead of repeatly bashing on your buttons.

How to know Hideo Kojima's exact date of birth:
At the beginning of the plant episode at the first node enter the name "Hideo 
Kojima" and the date of birth blood type and country will automaticly be set.
