Hint: Stealth Suit (MGS)
To get the Stealth, wich makes you invisible to all enemies except for Wolfs and bosses, play up until you get to Ocelots Torture Rack. Submit to Ocelot by pressing SELECT. After the game is beaten, you will get the bad ending where Meryl dies and you escape with Otacon. He will give you his Stealth suit. Watch the credits, then save your game. After you save, go to the Main Menu and load your game. Look in your inventory, you will find the Stealth Suit.

Hint: Defeating Sniper Wolf (MGS)
To defeat Sniper Wolf, you need to go all the way back to the Armory and go into the room with six mini-rooms inside of it. Go into the top-left room using your recently acquired level 5 key card. Inside is a PSG-1 and some ammo for it.

Now go back to Sniper Wolf. You should have picked up some Daizepam by now. This will allow you to aim your PSG-1 without it shaking. Go back to Sniper Wolf and shoot her with your PSG-1.

She may be hard to spot and times because she likes to hide behind things. Look for her breathe, and wait for her to come out. Equipping your thermal goggles will also help.

Hint: Shy Meryl (MGS)
When walking around with Meryl, if you 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
