PS3 | Submitted by Davo5000Best Way To Defeat Crying Wolf
Under The Tanker
The best way to defeat Crying Wolf is to hide under the tanker in the middle of the field and wait until she comes out and open up and then shoot her. Its best to have an sniper rifle with a silencer. In the process of waiting for Crying Wolf pick off the other people running around. It takes a while to defeat Crying Wolf due to the fact that she only comes out every so often, but it's worth the wait if no life is lost and everything is done undercover. Crying Wolf and or the other people will never find you.

PS3 | Submitted by metal gear rexGetting The Five Statues
In Act 1, when you have to fight the frog soilders, either don't kill any of them or use the MK II to make them fall asleep. If you did this correctly then there will be a frog solider statue inside the garage near where u get out.
On to the BBs, all you have to do is use the MK II on them (you can use the mantis doll on screaming mantis and you will still get the statue).
Location of Beast statues: LO's statues is on a bed in one of the rooms. RR's is on the top floor. CW's is near the bulding were you leave (on the right side of the building). And SM's is a the door where u game through.
You must get the statues before the three minutes end (except for crying wolf, you can get that statue after both battles.
Once you get the five statues and beat the game you will get the solar gun.
PS3 | Submitted by email@example.comLiquid Snake Strategy
when you face him you will have four rounds of him changing his "style" here is an easy way to win.
1. When the round begins he will charge at you. First combo punch him to knock him down, and then rush at him before he gets up. Hold L1, and when he gets up, press R1 twice and the first punch should break his guard. The second punch will get him down and do some damage repeat this until the cutscene.
2. This round is very simple, just dash out of the way when he winds up for the punch. after you dodge, you can either hit him with a combo or the L1 R1 method.
3. All you have to do is combo, combo, combo, and you will win.
4. This round you have to hit him 7 times. Very simple.
PS3 | Submitted by Makenna aka: YOOHOO LOVEREasy Vamp battle
Vamp is a total sucker for the solar gun. When the battle begins, charge the solar gun all the way, then when vamp runs toward you shoot him, he will immediately fall. You only have a few seconds before he gets back up, so hurry and unequip the solar gun and equip the syringe naomi gives you in the second act. Sneak behind Vamp and right when he's getting up hold R1 and get him in a CQC chokehold. Then press triangle and snake should inject vamp with the nanomachine suppressors.
PS3 | Submitted by seeminglysmartperitEven easier way to kill a Gekko
All you need is the .50 caliber sniper rifle and a keen eye. Maybe a little bit of good timing. Equip it, take aim at the head, and fire. I hope you like 1 shot kills...
PS3 | Submitted by someoneEasy Way To Kill Gekko
This hint only works after you have defeated crying wolf. All you have to do is to aim at a Gekko with the railgun, wait for it to charge full, pull the trigger and enjoy Gekko dying with 1-shot-kill. Note: aim for its head, not its legs.
PS3 | Submitted by EugeneLoads Of Batteries

PS3 | Submitted by GySgtAceBeating Screaming Mantis
First have the mosin nagute (the tranquilizer rifle), the M-14, and the syringe. First use the syringe so that she can't control you. Next shoot The Sorrow puppet with the M14, be careful because you don't want to kill Meryl. After the Sorrow doll falls pick it up so the frogs stop shooting. The shoot the Mantis doll with the mosin nagute until it falls, then shoot Screaming Mantis with the Mantis doll then shake the controller like crazy (If you want to finish her quick, then get the Mantis doll). To beat Screaming Beauty just shoot her with the tranquilizer hand gun. If you killed her by pysche you get her facecamo and you get any of her dolls that you shot out of her hand.
PS3 | Submitted by SmoresEasy Way to Kill a Gekko
Take out your tranquilizer pistol and fire it at the Gekko's legs then when it falls run to the front of it (it wont attack you) and shoot at it's head with an assault rifle.

MGS1 Otacon - To find the ghost of Otacon (which sn't technically a ghost since Otacon is still alive, but oh well), you must go into Otacon's old office. After putting in the password for the security, look above the desk with the monitor you put the code in. You should see a Policenaughts poster. Take your camera and aim slightly to the left (a couple of inches) and take a photo, if done in the correct place, you should see an image of Otacon from MGS1.
Liquid Snake - After entering the Snowfield/Comm Tower area and defeating Crying Wolf, head to the right of the Comm Towers from where you entered the area, before Otacon tells you to change the disc. You should find Liquid's Hind D you fought in MGS1. There will be a flashback to when you destroyed his chopper, which you can listen to for an easy 1000 DP. Then pull out the camera and aim at the cockpit, Liquid's ghost should appear. Because of the blizzard it can sometimes be hard to see the ghost, so it might be easier to look at the photo in the photo album and edit the photo to see it.
