Drebin points with no effort..

Okay firstly put in the password in the extras menu for the patriot with infinite ammo (pkhhnwhsjt). Then play your way through the game until you reach Act 5 just before the corridor with the microwaves. There will be a series of metal platforms with some of the dwarf gekko things there..they will keep regenerating. Put on auto aim and equip the patriot..then secure the L1 and R1 buttons with some sticky tape etc...come back a few hours later and your D.P. Will have increased..although the dwarf gekko aren't worth much it's easy money for minimal effort. And because Drebin's prices are low in Act 5 it's a good way to get the bandana/stealth gear before the end of the game..enjoy.

No alert in shadow moses

When protecting the MK.3 a Gekko will appear and try to stop otacon's little robot from opening the door.IF you're going for the stealth suit and trying not to get any alerts then quickly move under the gekko while he's in the second floor and take cover by the big missiles.Take out any assault rifle with a lot of bullets and start shooting at it.Caution will appear in the top of the screen and the gekko will remain in the second floor trying to scan the area,looking for you.Stay in the same area while shooting at him so he doesn't spot you.Once otacon is done throw a chaff grenade and quickly head over to the door.

Naomi's skirt

When inside the research lab with Naomi,snake in one of the scenes will drop his cigar.He's going to bend down and pick it up.Before he picks it up,press L1 ,even though it wont tell you to,and look to the right and snake will look at her skirt.

Defeating Vamp

First, use the Tranq. Gun to reduce Vamp's psyche to zero. He should pass out. Then quickly equip the stringe/Anti-Nano shot and use CQC to grab Vamp then press Triange. You must be not holding anything but the stringe, otherwise it won't work. Instead of cutting the throat, Snake will 'give' Vamp a shot of the Anti-Nano, making Vamp mortal, which will make him able to die and to stay dead.

Good Hunting!

How to defeat screaming mantis

Ok here's how you defeat screaming mantis first you have to use the syringe to free yourself from her control if you don't do it your'e screwed then you aim at the glowing blue doll that stops her control over the dead frogs I know your'e thinking you must save meryl just us CQC and use the syringe on her she will go down and not get up for awhile you must focus on the bigger threat namely the dead bodies with guns they can't die so you must keep hitting the blue doll once she drops it you must pick it up then she can't control the dead bodies start firing on the gold glowing doll when you knock that down screaming mantis is almost defensless she only has two attacks and you must use the gold doll on her and you kill her

Shadow moses

If you are trying to get past the little black balls in shadow moses without getting an alarm just use smoke grenades as diversions.Throw them to a corner of the room you are in(wherever there are little robots)and they will automatically go to wherever the smoke is coming from.

Akiba (Johnny) Trademark Pose

When fighting with Meryl and her Rat Pat. 01 squad, try knocking out or tranquilizing the members of the team.

Both Ed and Johnathon go down normally, Meryl is unaffected by the darts, and as for Johnny, or "Akiba", he sticks his rear end high in the air, much like he did in MGS1.

Thought it was a cool little quirk.

Beauty Bosses Photoshoot

With all the B&B bosses, while in their beauty stage, if you wait around for about two minutes, you'll find yourself in an all white level, just you and the beauty.

As an added bonus, when you pull out your camera, the beauty will make different poses for your camera. Probably a quirk that the beauty bosses were modeled after actual models.

Easter (Egg) Island

In Shadow Moses, when proceeding through the now non-elctrified area, stop and look through one of the glass doors. You can see a Moai statue head on a file cabinet. Statues like this are scattered throughout most Kojima games.

M1911 Code!

The code for the M1911 has been revealed! It is 1aytmmymhk (use lowercase letters) The M1911 is the gun used by Naked Snake in MGS3. It's superior to the Operator and uses the same ammo. Unlocking the M1911 will also unlock M1911 suppressors for purchase from Drebin.

Half-Off Sale AND Exclusive Sale!

Half off sales are always at stage 5 at the Outer Heavens. Drebins' shop will be half off price. Also, on Wednesdays and Sundays, the sales will be 20% off. Some people might think being in the Outer Heaven on Wednesdays or Sundays will net them 70% off sale. But it won't, the most you can is 50% off. Just to help out people trying to get the bandana.

How to easily follow the resistance member

Use the beauty face camo and the resistance member wont recognize you as an enemy. The pmcs will just ignore you

How to beat Vamp

The trick to beating Vamp is rather simple, drop his health down to zero and run up behind him, equip the syringe Naomi gave you and inject him using Triangle.
