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 until 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.
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
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
Cardboard Box B: Get shipped to Nuke Depot, works in Heliport and
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!
Secret Ghost Pictures:
After you get the Camera, take pictures of the following locations to see
hidden ghost figures of the development team. To view them, select the 'Album'
option at the main menu.
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.
